The restoration of the Seafarers’ Chapel floor at Bristol Cathedral has been recognised with a Church Transformation Award, highlighting a project that combines sensitive stone conservation with improved accessibility within a significant historic setting.
Delivered by Cliveden Conservation in collaboration with Nick Cox Architects and the Cathedral team, the works formed part of a wider programme aimed at making the building more welcoming and accessible while preserving its historic fabric. The award will be formally presented at the 2026 Church Transformation Awards ceremony in May.
 

The 14th-century Seafarers’ Chapel contains an important collection of ledger stones and wall monuments, but decades of wear had left the floor uneven and difficult to navigate. The project sought to resolve these practical challenges without losing the character and historical integrity of the space.

A spokesperson for the Cathedral said improving access was central to the scheme. “Transforming access in the Cathedral is a key priority for us as we work to ensure the building is open and welcoming to all,” they said. “The Seafarers’ Chapel floor was the first step, and we were really pleased with the result.”

Cliveden Conservation was appointed to undertake the principal phase of stone repairs alongside the conservation of marble memorial tablets. The approach prioritised retention wherever possible. Large historic ledger slabs were conserved in situ, while decayed Pennant sandstone paving was carefully lifted and replaced using Forest of Dean Pennant sandstone sourced from Barnhill Quarry to match the original material.

Each replacement stone was set out and cut precisely to align with the historic floor pattern, ensuring continuity across old and new work. According to Tom Flemons, director and Bath workshop manager at Cliveden Conservation, maintaining that balance proved central to the project’s success.

“This was a collaborative process involving masons, conservators and the wider client team,” he said. “The challenge was maintaining the character of the floor while renewing well over one hundred individual stones.”

The dismantling phase was carried out under an archaeological watching brief, revealing previously unrecorded burial vaults beneath the chapel floor. The intervention also allowed the discreet installation of new acoustic and audio cabling, demonstrating how conservation projects increasingly integrate modern infrastructure within historic environments.
Accessibility improvements were also a driving factor behind the project. The floor was levelled and new stone, steel and oak ramps introduced, including a new ramp providing step-free access to the Lady Chapel and improved circulation routes between the North Choir aisle and Choir.

Kathryn Harris, Cathedral Architect at Nick Cox Architects, said the scheme required “expert craftsmanship to sensitively level new stone slabs around existing monuments, which were conserved in situ”. She added that the permanent access routes represent “an important step forward in the Cathedral’s vision to make this historic building accessible for everyone”.
The award recognises not only the quality of workmanship but also the evolving role of conservation projects within ecclesiastical buildings. Increasingly, heritage stonework schemes are expected to deliver inclusivity, functionality and long-term sustainability alongside traditional repair.

For Bristol Cathedral, the Seafarers’ Chapel restoration demonstrates how careful material selection, skilled masonry and collaborative conservation can renew historic spaces while ensuring they continue to serve contemporary congregations and visitors alike.

As we’ve been reporting, the industry has been moving into a period of increased scrutiny of fabrication environments, particularly around dust management, workforce protection and demonstrable operating standards.

The Worktop Fabricators Federation (WFF) has introduced a new Quality Mark scheme intended to raise professional, operational and health-and-safety standards across the kitchen, bedroom and bathroom (KBB) fabrication sector.

Developed through industry collaboration and informed by occupational hygiene research, the initiative establishes a structured framework through which fabrication businesses can benchmark working practices, demonstrate compliance and pursue continuous improvement.

During a recent WFF industry meeting, Kevin Bampton, chief executive of the British Occupational Hygiene Society (BOHS), addressed members on the importance of embedding occupational hygiene principles into everyday fabrication processes, highlighting the role consistent standards can play in improving safety outcomes across the sector.

WFF operations officer Nigel Fletcher underlines that the Quality Mark is intended to provide a clear reference point for clients and specifiers assessing fabrication competence. He said the programme establishes “a clear benchmark for professionalism, safety and operational excellence,” while rewarding businesses that invest in best practice and workforce protection.

The federation is encouraging KBB designers and specifiers to work with fabricators able to demonstrate recognised standards and independent assessment, reflecting wider industry moves towards transparency and accountability within supply chains.

Under the new scheme, WFF members will be classified across a three-tier membership structure:

• Provisional Status –  Businesses working to improve processes, build standardisation, and develop operational capacity, supported by WFF mentoring and guidance.
• Approved Member – Companies demonstrating strong systems, proactive management, and reliable performance metrics.
• Audited Member – Best-in-class operators demonstrating continuous improvement and industry-leading practices, independently inspected by a BOHS auditor in addition to WFF assessment.

While only audited companies will be permitted to display the official Quality Mark, WFF says the tiered approach is designed to encourage progression rather than create barriers to entry, allowing businesses to improve processes while working towards independently verified best practice.

Several member companies have contributed to the development of the framework, including PWS Distribution Ltd, Bellagio Stone Ltd, Natural Stone Surfaces Ltd, Granite Tops (UK) Ltd, The Quartz Worktop Company Ltd and Stone System of London Ltd, which collaborated with scientific and industry stakeholders during development.

The federation believes the Quality Mark will help improve consistency across fabrication businesses while supporting safer working environments and strengthening confidence among specifiers and clients commissioning KBB worktop installations.

For some, olives are not a food group that the palate ever quite grows to appreciate. 

For those of us who can’t get enough of them, there is that slightly peculiar trade-off, where intense flavour and enjoyment are offset by the need to dispose of the hard stone within. And perish the thought of accidentally biting down on one.

As the search for lower-impact surface materials continues to push designers beyond convention, one ingenious Cypriot company has seized on those surplus pits as a means to produce a solid surface for the built environment.  

Pit-To-Table reframes the by-product at an agricultural scale with its bio-composite, Pit Board. The panels come in a standardised 18mm-thickness, and are manufactured without the need for a secondary substrate. The company states that at least 60% of the material content comes from agricultural waste, positioning it within a growing category of plant-based construction products aimed at reducing reliance on petrochemical binders and virgin resources.

The olive pits are graded through an industrial sieve into four sizes, producing a varied surface texture that reads differently depending on light and distance. Up close, the material reveals a dense, tactile field of fragments. Rather than treating waste as filler, the pits themselves become the visible aggregate, giving the board a granular, almost terrazzo-like appearance, but with a softer, more organic feel.

Developed in Cyprus, Pit Board draws on the by-products of olive cultivation, a long-standing agricultural industry across the Mediterranean. By redirecting what would otherwise be discarded organic matter into construction, the material connects local waste streams with global design supply chains.

Stone façades at two prominent buildings within Durham’s UNESCO World Heritage Site have undergone extensive conservation and repair following the completion of a major heritage project led by Classic Masonry.

Appointed by main contractor Vest Construction, the specialist masonry firm carried out façade repairs to Cosin’s Almshouses and the neighbouring Pemberton Building at Palace Green, addressing significant weathering, structural cracking and long-term water ingress while preserving the historic character of the Grade II listed buildings.

Constructed in 1666 by Bishop John Cosin on the site of a former 15th-century grammar school, Cosin’s Almshouses were originally created to house clergy widows. The adjoining Pemberton Building, designed by W.D. Caroe and completed in 1929, is home to the Durham Union Society, one of the world’s oldest student debating societies. 

Commissioned by Durham University as part of its Non-Residential Refurbishment Programme, the £1.8million scheme included stone repairs, sensitive repointing of eroded masonry and the replacement of three carved entrance plaques. Archaeological monitoring undertaken during the works revealed 17th-century foundations and a probable medieval culvert, underlining the complexity of working within a historically layered site.

Gavin Vest, managing director at Vest Construction, said: “We were delighted to have been appointed again by Durham University to deliver such a significant heritage project. Cosin’s Almshouses and the Pemberton Building are not only central to the city’s historic skyline but also hold deep cultural and academic importance.” He added that Classic Masonry’s conservation expertise was “invaluable to ensuring the façades are returned to their former glory, preserving their architectural detail for generations to come.”

The masonry package involved careful repair of deteriorated stonework alongside targeted replacement where decay had become irreversible. Classic Masonry managing director Mike Moody highlighted that the entrance plaques required particularly specialist intervention. “The three existing entrance plaques were in such a poor state of disrepair that… replacement was required for various sections of these historic features,” he said. “Classic Masonry undertook extensive traditional hand carving at our workshops… showcasing the exceptional craftsmanship and talents of our carver masons.”

Sustainability formed part of the conservation strategy, with sound roof flags salvaged and reused to minimise material waste. What’s more, close collaboration between conservation officers, consultants and construction teams ensured minimal disruption to university operations while maintaining strict heritage requirements.

The project marks the fourth Palace Green scheme delivered by Vest Construction over seven years, with Classic Masonry engaged on two projects requiring specialist stonemasonry expertise. It’s proving to be a busy period for Classic Masonry, having carried out extensive restoration of churches in the North East, as well as helping Sunderland City Council to landscape Riverside Park.

Once home to more than 1,000 people, The Cabrach’s population has dwindled to less than 100 today. Located on the high boundary between West Aberdeenshire and Speyside, at the heart of Historic Banffshire, the rural estate has experienced decades of decline.

But one recently completed architectural project represents a visual indicator of change in the area, led by a group of passionate local residents. Having come together in 2013 to create The Cabrach Trust, the team has produced a portfolio of projects including cultural events, nature recovery initiatives, rural skills and wellbeing workshops, as well as employing the services of Scottish practice Collective Architecture to design The Cabrach Distillery.

The development transforms the ruined 1849 steadings at Inverharroch Farm into a working single-malt whisky distillery — the first legal whisky production in the area for more than 170 years. Nestled on the edge of the Cairngorms National Park, the area was once a hotbed of Jacobite rebels and smugglers, as well as local farmers, many of whom sought to supplement their minimal livelihoods by producing ‘Uisge Beatha’, or ‘ Water of Life’...also known as Whisky.

Rather than operating solely as a visitor attraction, the distillery forms the economic centrepiece of a long-term strategy to stabilise and repopulate this remote Highland community.  The architectural approach begins with repair rather than replacement. Existing stone steadings, deeply embedded in the agricultural history of the landscape, were carefully retained and adapted, allowing the project to grow directly from the site’s inherited fabric. Weathered masonry walls were consolidated and reused wherever possible, maintaining the character and layout of the original farm buildings while accommodating contemporary production requirements.

Reclaimed stone from nearby derelict structures supplements retained masonry, which provides thermal stability well-suited to distilling and maturation processes. But the decision is an aesthetic one too, ensuring continuity of colour and texture, which visually anchors the distillery within the surrounding landscape. Sustainable timber sourced from local forests complements the stone construction, reinforcing an approach rooted in local resources and traditional building knowledge rather than imported systems. The resulting architecture feels grounded, its mass and permanence responding naturally to the exposed Highland environment.

Operated as a community-owned social enterprise, the distillery reinvests future revenues into local housing, employment opportunities and environmental initiatives, ensuring the building functions as long-term infrastructure rather than a singular architectural gesture. What’s more, extensive landscape works, tree planting and new walking routes extend the project beyond the building itself, positioning the distillery as part of a wider ecological and social regeneration effort.

The Cabrach has a long association with whisky production, both legal and illicit, and re-establishing whisky making in the area, therefore, reconnects the community to its cultural history rather than introducing an entirely new industry. Jonathan Christie, Chief Executive of The Cabrach Trust, describes the emotive impact: “The idea of a Single Malt Scotch Whisky distillery, operated as a social enterprise, housed within a once ruinous historic steading, anchoring the regeneration of a proud rural community, is an idea that’s easy to get misty eyed about.”

For Collective Architecture, the project demonstrates how reuse-led construction can support both environmental responsibility and social resilience. Working within an existing stone framework allowed the architects to prioritise longevity, repair and material continuity over novelty. The architecture avoids spectacle, instead achieving presence through restraint: repaired masonry, robust agricultural forms and carefully judged contemporary interventions.

Further phases, including a heritage centre and café, will expand the site’s public role, but the distillery already illustrates a wider lesson for the industry. Low-carbon construction is often less about new materials than about recognising the value of those already in place. At The Cabrach, stone functions simultaneously as structure, memory and future investment — a material capable of carrying both history and community forward. Slàinte to that!

While the exhibition What Lasts Doesn’t Always Hold Shape may have drawn to a close following a run at Hypha Gallery, 1 Poultry, London, the impact of the work on display and the rousing presentations and debates it stirred can still be felt. 

Indeed, while the event has reached its natural conclusion and ended, one standout discussion organised by Material Index underlined the importance of responsibility, reuse, and, notably, permanence within the built environment. 

Set among the sculptural works, which explored material memory and impermanence, the discussion extended the team’s ongoing work and brought together architects, engineers, artists and material specialists to consider an all-important but seemingly overlooked question within the industry: what happens to materials when buildings reach the end of their lives?

Following an introduction from curator Rebecca Jak, Olivia Daw, Product Lead at Material Index, framed the evening around this central question, while adding another drawn from the exhibition: what is allowed to last? The prompt shifted discussion away from demolition as an endpoint and towards the decisions, knowledge and detailing required to enable reuse.

The conversation was led by Bora Malko (Material Index), Katie May Boyd (Studio Tip), Tom Hesslenberg (Elliott Wood Engineers) and Laura Mohirta (Barr Gazetas). Participants reflected on the increasing emphasis placed on retaining structures in situ, while acknowledging the practical challenges that emerge when materials must be removed, assessed and reintroduced elsewhere. What appears straightforward conceptually quickly reveals structural, contractual and logistical complexity.

Another recurring theme was visibility: can reclaimed material be recognised as such, or does reuse remain largely invisible within finished architecture? The question highlighted how aesthetic expectations often sit uneasily alongside circular ambitions. Data and accountability also surfaced repeatedly, with perhaps more questions asked than answered, reflecting a broader issue within the industry. Who holds accurate records of what a building is made from? Who signs off on reused components? The key problem that remains being that without a clear transfer of material information, viable elements risk becoming waste. As Malko asked the room: “When you design something, how often do you think about specifying something reclaimed instead of something new?” 

For Material Index, the event reflects a wider ambition to normalise reuse within everyday specification practice. Through its construction marketplace for reclaimed materials, the team hopes that conversations around deconstruction are no longer theoretical but become fundamental to changing industry behaviour. As Daw explains, the organisation “is actively bridging the gap between buildings coming down and buildings going up, making it easier for designers and specifiers to sell, donate and source reclaimed materials and put them back into new projects.”  

The conversation around deconstruction isn't abstract for the team and is what informs how Material Index builds the tools and relationships needed to make reclamation viable at scale. As Daw stresses, “the more the industry can be brought into honest conversation about these friction points, the closer we get to a built environment where more is saved, more is reused, and less is lost.” 

The Stonemasonry Company is a specialist contractor focused on advancing the use of natural stone in contemporary construction. Working across restoration, new-build and research-led projects, the company combines traditional craft skills with digital fabrication and engineering collaboration to deliver complex stone structures. Its work increasingly explores stone as a low-carbon structural material, and plays a central role in the Stone Collective, contributing to industry research, prototyping and education around all things stone construction. We asked CEO Alex Betrand for some insights into the work that goes on behind the scenes.

What are the biggest lessons you have taken forward from your original training? 

My training with the Compagnons du Devoir du Tour de France in France gave me a strong foundation in stereotomy, geometry and the structural understanding of stone. The key lesson was that stone must be understood as a structural material first, not just a finish. That education instilled precision, discipline and respect for the material, which still guides my approach today.

Which project/s are you most proud of being involved with and why?

At The Stonemason Company Limited we focus on highly bespoke and technically challenging work, particularly sculptural staircases. I’m most proud of the development of pre-stressed stone systems that allow extremely slender stone structures while maintaining safety and durability. These projects demonstrate that stone can be innovative and contemporary, not only historical.

How integral are materials to your day-to-day?

Materials are central to everything we do. Stone is not simply a surface for us; it defines the design and engineering of a project. Every day we discuss stone with architects, engineers, quarries and fabricators—covering structural performance, sourcing, fabrication and installation. Even with digital tools, direct contact with the material remains essential.

What do you feel are the main challenges facing the stone and surfaces industry today?

One challenge is perception. Stone is often seen as either decorative or expensive, rather than as a durable structural material. Another challenge is the gradual loss of specialised knowledge and skills within the industry. Finally, the industry must communicate more clearly the environmental advantages of natural stone compared with many manufactured materials.

In your opinion, what are the positives of using stone in the built environment?

Stone offers exceptional longevity and durability. Properly designed stone structures can last for centuries with minimal maintenance. It is also a natural material with relatively low processing compared with many modern building materials. Architecturally, stone brings a sense of permanence and authenticity, connecting buildings to geology and place.

How does sustainability shape your thinking and decision-making, and how do materials fit into this?

Sustainability is central to our thinking at The Stonemason Company Limited. We prioritise sourcing local stone where possible, minimising waste and designing structures that maximise the natural strength of the material. Because stone can last for generations, it offers a strong long-term sustainability argument when considered over the life of a building.

Natural stone will form the focus of a dedicated programme of talks, films and case studies at the Stone & Surfaces Show, taking place at ExCeL London from 12–14 May. As the UK’s only trade exhibition with a section devoted entirely to natural stone, this year’s edition expands its educational offer across three venues. The Main Stage, Surfaces Cinema and Architects’ Theatre will examine stone’s role in contemporary construction, specification and low-carbon design.

Proceedings open with two Main Stage panel discussions moderated by George Clarke, exploring the growing interest in stone as a structural material. The first centres on the Stone Demonstrator at Earls Court, with contributions from Justin McGuirk of the Design Museum’s Future Observatory, Marcus Paine from Hutton Stone; engineer Eleonora Regni from Webb Yates; and Pierre Bidaud from the Stonemasonry Company. A second session examines the barriers to specifying structural stone at scale, bringing together architects, developers and researchers to discuss challenges around regulation, cost and industry knowledge.

Interior specification is also addressed through a panel led by Athena Stonecare, highlighting common issues around stone selection and maintenance in residential interiors. Case-study discussions then turn to recent projects advancing structural stone construction, including Trehus in Maidenhead, a timber-framed office building clad in natural stone and targeting a 40% reduction in embodied carbon compared with conventional steel construction. Amin Taha will also discuss Groupwork’s Finchley Road development, along with Steve Webb from engineers Webb Yates, and Ben Ayling from stone supplier Lundhs.

Trehus

The newly introduced Surfaces Cinema presents architectural photography and documentary film exploring the cultural and environmental narratives of stone. Photographer Chris Hopkinson will open the programme with a curated projection and short film documenting Portland stone quarrying. 

Milestone

Feature documentaries Milestone and Unlocking Indigenous Stone continue the theme, tracing the journey of stone from quarry to contemporary architecture while examining craftsmanship, material heritage and the potential for locally sourced stone in low-carbon construction.

Architect-led presentations further demonstrate stone’s versatility across scales. Fieldwork Architects will discuss Wishing Well in Jersey, where locally quarried granite and limestone define a contemporary domestic interior, while Studio Folk founder Edward Powe and Hawkins\Brown partner Marko Neskovic present recent projects exploring stone detailing, materiality and urban landscape design.

Klaas De Rycke

At the Architects’ Theatre, engineers and designers focus on technical innovation and reuse. Speakers from Webb Yates present lightweight stone grid structures, while Bollinger+Grohmann partner Klaas De Rycke examines expanding structural applications for stone. CSK Architects will discuss projects centred on stone reuse, challenging conventional assumptions about lifecycle and permanence in construction.

Wishing Well

The expanded programme reflects a wider shift in how natural stone is understood within the built environment. “The programme highlights how this ancient material is increasingly vital to the future of low-carbon construction,” says Sam Patel, Divisional Director of the Built Environment Super Event, which brings together the Stone & Surfaces Show alongside UK Construction Week and Futurebuild at ExCeL London. 

Together, the co-located events aim to position natural stone not only as a traditional craft material, but as an active contributor to contemporary sustainable architecture.

“Every child deserves to learn in a classroom that feels warm, dry and healthy.”

For those of us who attended school in the 20th Century, it might be a surprise to read that this statement is not one dredged up from the last millennium, but in fact one posed by the team behind a new retrofit initiative.

Build With Hemp aims to demonstrate how bio-based insulation can play a role in addressing issues cold, damp and mould in schools during the winter, along with the reverse problems in the warmer months. The team has announced a scheme to deliver a targeted insulation upgrade to a UK school, supplying materials and installation at no cost up to £25,000. 

It has been shown that, along with poor sound insulation year-round, such conditions affect not only the performance of the building but those of students and staff alike. The chosen project will act as a case study, highlighting the potential of industrial hemp-based systems to improve building performance while supporting healthier internal environments.

Build With Hemp is inviting nominations from local authorities, architects, contractors and education estates teams for a suitable project. The selected building will undergo a monitored intervention, with findings shared more widely across the construction and education sectors.

Michael Walker, CEO of Build With Hemp, says the initiative is intended to demonstrate practical, scalable alternatives to conventional materials. “We believe healthier buildings should not be a luxury. If a classroom is cold, damp or acoustically poor, that has a direct impact on pupils and teachers. Through this project we want to make a tangible difference, while showing what is possible with modern, certified, bio-based construction materials.”

Hemp-based insulation systems have been used in parts of Europe for several decades, particularly in education and residential settings. Walker adds: “This material is already proven in large-scale projects across Europe and is well suited to public buildings such as schools, where durability, compliance and measurable performance are essential.”

As pressure grows to decarbonise existing buildings while improving user experience, the project offers a small-scale but practical test of how natural materials might be deployed more widely within the all-important education sector.

Nominations for the scheme opened on 11th March and close on 17th April, with the chosen project due to be announced at Futurebuild 2026 in May, where the company will also be exhibiting at stands F82 and G40.

While having only formed some seven years ago, Goldstein Heather has already established itself as a studio built on timeless design and enduring forms. 

In Stamford Brook, their recently completed project, West London House, once again galvanises this status. Reworking a narrow end-of-terrace Victorian property through a substantial lateral extension, they have combined restored brick fabric with a contemporary masonry with an elegance and attention to detail in keeping with the properties surroundings.

Having bought the original house a decade ago, owners Rowan and Angelina Bamford seized upon the chance to purchase the neighbouring Expedition House, a former 1930s Territorial Army building. This offered the rare opportunity in London of allowing the architects to extend the original house sideways. What began as a refurbishment evolved into a four-storey intervention that almost doubles the usable footprint, creating nearly 500m² of internal space across old and new structures.

For the clients, the move was driven as much by spatial quality as by family dynamics. Not only did the original house’s tight plan and fragmented layout limit daylight, but the multigenerational household were finding that social interaction was being hindered too. The answer: a new extension that reorganises the plan around volume, light and material continuity.

At the heart of the scheme is a double-height space that draws daylight deep into the interior, supported by an east–west orientation and a green outlook to the front. Openings are carefully positioned to frame views of the street, treetops and rear garden, while maintaining a sense of enclosure. The result is a sequence of interconnected spaces that balance openness with domestic scale.

In terms of materials, the project juxtaposes the restored Victorian fabric with a fresh and contemporary palette that emphasises permanence and tactility. The original façade has been stripped back and repaired, with brickwork repointed and historic details reinstated. In contrast, the extension adopts a lighter-toned yellow brick and lime-based render, establishing a distinct but complementary identity.

Tasteful curved masonry forms are a defining feature throughout, appearing both externally and internally. Arched openings and sculpted surfaces catch light and soften transitions between spaces, lending the building a sense of weight and continuity. The upper level includes an accordion-like façade, which juxtaposes the smooth arcs, yet still manages to subtly soften the exterior through fractured light patterns.

Inside, natural materials continue to shape the spatial experience. A long marble island with pronounced green veining anchors the kitchen, paired with bespoke ash joinery by Sebastian Cox. The detailing extends to cabinetry with a textured finish that echoes the articulation of the upper-storey façade, reinforcing a consistent architectural language.

The all-important circulation is organised around a curving timber staircase that widens as it rises, increasing the sense of openness and access to daylight on upper levels. The layout accommodates both shared and private uses, with interconnected children’s rooms spanning old and new sections of the house, and a more secluded top-floor suite.

Client Rowan Bamford highlights the social transformation of the house: “We were able to create a light-filled, connected home that suits the way our family lives… a space designed with the future in mind.”

From a construction perspective, the project integrates a number of low-impact strategies, including high levels of insulation, hemp-based building materials and solar panels, contributing to reduced operational energy demand and near carbon-neutral performance during summer months.

For the architects, the scheme represents a consolidation of their design approach. “The West London House crystallises the design ethos of our studio,” says director Giles Heather. “The geometrical forms that articulate the exterior continue through to the interior, where intimate spaces connect with more expansive communal areas, filled with light from both east and west.”
