L’Envol is a shimmering new installation by Suffolk-based Giles Miller Studio, which captures the eye and imagination of visitors to the Champs-Élysées in Paris. While the vast vertical surface may initially conjure the rippling surface of a dark body of water, it is in fact made up of thousands of glazed ceramic discs. 

But much like water, the installation takes on a life of its own depending on the time of day, ambient light levels, and the viewer’s vantage point, making each visit entirely unique.  Known for their playful and often poetic movement of light across surfaces and objects, the studio set out to create a visually arresting artwork that begged to be touched. French for “the flight”, the installation is designed to elevate passersby’s experience, creating a moment of lift in their day that’s full of visual and tactile intrigue. 

Working closely with trusted Italian artisans, the team returned to ceramics for its enduring quality and opted for a mottled chrome finish, which both reflects and distorts the light and the surrounding environment. Each disc is handmade and therefore has its own distinct character and surface quality, which, when combined en masse at varied angles to one another, creates a monumental and ever-shifting artwork.

Those taking a stroll down London’s vibrant Redchurch Street recently have been treated to a new facade made from a very unique solid surface.

Luxury retail store UJNG plays host to an array of contemporary independent fashion designers, and now has a 3D exterior made from Oyster[crete]. The material is the brainchild of Matter Forms, a studio led by Mooka Srisurayotin, who researched and experimented with oyster shells over a 2 year period before launching the surface in 2023. 

Circularity is at the heart of the studio’s approach, with this innovative material transforming shells leftover from the food industry that would otherwise be discarded as waste. An alternative to concrete, Oyster[crete] consists of around 80% waste, and this latest iteration of the product comes in two cast formats. 

When joined together like here on UJNG, the U and J shapes create a relieved surface of undulating, curved and straight-lined extrusions. An eye-catching facade with a planet-positive narrative to tell.

This summer, Caesarstone has launched a new range of countertops that put beauty and wellbeing at the forefront of design. The ICON range represents a major new direction for the brand and industry as a whole, with the introduction of these patent-pending ‘advanced fusion surfaces’ extending an already expansive portfolio.

Known for their premium craftsmanship and use of natural materials, the design team behind ICON has spent considerable time developing the range, which utilises 80% recycled content, while containing no more than 1% crystalline silica. The harmful and even potentially fatal effects of breathing in respirable crystalline silica are long established and an ongoing concern for those sourcing and working with such materials - not least fabricators and installers. In almost entirely eliminating the use of the substance, ICON offers an unparalleled peace of mind, while at the same time aiming to reduce environmental impact.

Caesarstone MD, Edward Smith, explains the brand's rationale, “This groundbreaking formulation speaks to Caesarstone's deep-rooted commitment to innovation, meeting the growing demand for safer, more environmentally conscious products. With these new ICON surfaces, we invite designers and industry partners to look deeper at the possibilities available.”

As has become customary, the team has also given aesthetics the same rigorous approach, drawing inspiration from the organic forms and textures just beyond their workshop window. As Mor Krisher, Head of Product Design, explains, “We decided on a concept of transparency and multi-dimensional layers for the new collection, and the next step was to find inspiration in nature's materials and their unique transparencies. After some exhilarating research, we headed back to our workshop and started creating.”

The outcome is a range that mirrors marbled veins, flowing water, and opalescent stone, which, as Mor is keen to point out, is also thanks to the teams new, “advanced fusion technology, which creates intriguing layers and flowering textures, in a calming colour palette inspired by the transparency of mists, moonlight, seafoam and precious stones.” Products such as Moonlight and Ocean Sage do just that, creating a rich visual and textural experience and a timeless beauty.

Friday 12th September sees the launch of the Stone Library at Sheffield Hallam University. Located in the newly completed Redmires Building, the collection has evolved from an almost-lost resource first put together in the early 90’s.

Brothers Scott and Geoff Engering created the Triton Stone Library for their London-based company Triton Building Restoration Ltd as a way to show specifiers suitable materials for restoration, sympathetic extensions and new buildings. The samples range from the indigenous limestones, sandstones, granites, and slates, but having been of great use up until Geoff’s retirement in 2000, the collection was set to be thrown away - were it not for Scott’s intervention. With a keen desire to create a second life for the collection, Scott has been working with Professor of Stone Conservation, Elizabeth Laycock, and the stone samples now form the basis for the School of Engineering and Built Environment’s new library.

Elizabeth and her team will continue to add to the unique installation with low-carbon geomaterials and composites that are used in building conservation and in new-build construction. Students and professionals from Architecture, Geography and Construction disciplines alike are all invited to use the resource, with each sample in the library supplemented by an evolving online library.

For more information about the launch and the library visit:

Back in 2018, passersby of St Andrew’s Chapel near Maidstone in Kent would have been forgiven for dismissing the ancient building as a ruin, or missing the derelict site amongst the overgrowth altogether.

Now, seven years on, the Society for the Protection of Ancient Buildings (SPAB) are proud to present the fruits of an outstanding regeneration program, with stone at the heart of the project. 

Founded by William Morris and his fellow campaigners in 1877, SPAB is the UK’s oldest conservation charity, and bought this ‘sleeping beauty’ for as little as £60,000. Recognising the value in the medieval building, with it’s rich and varied history, the team have painstakingly transformed it into a luxury three-bedroomed home which now hits the market at £950,000. The project underlines SPAB’s ongoing dedication to giving old buildings a future, which involves casework, technical research and advice, education and training, awards, outreach and events across the UK and Ireland. 

As Matthew Slocombe, CEO of SPAB explains, "The SPAB approach involves understanding the building you’re dealing with to work out its story and structural development. By asking the questions: who, what, when, why, and how, the best conservation solution can be identified.  Ultimately that is the way to ensure an old building is treated sympathetically."

The outcome of the Old House Project demonstrates a sensitivity to the historic fabric of the building, while bringing it up to date for contemporary habitation. As such, future generations will be able to share in its observable history, creating a sense of connection and place that goes well beyond the beautifully textured surfaces. Indeed, the building truly hums with a past well lived - even if the space has remained empty for the past 50 years. Originally believed to be a gatehouse chapel for nearby Boxley Abbey, the chapel prospered from its locality to the Pilgrims’ Way, receiving donations from devoted wayfarers as far back as 1484 (indicated by tree ring dating of roof timbers). Built during a time of mulitplicite religious relics, the chapel house actually housed a silver clad finger of St Andrew. While built to last using the finest local ragstone and oak, the building suffered at the hands of political …with the dissolution of the monastaries some 50 years after it’s completion. However, having been passed to Tudor poet and courtier Sir Thomas Wyatt of nearby Allington Castle, the chapel remained in safe hands until it was later turned into a cottage in the 18th Century, and more recently used as a grocery in the late 20th Century.

Over the last seven years, SPAB has worked closely with Kent Archaeological Society, Historic England, local people and the council to uncover the building’s story and, even more importantly, to bring St Andrew’s back to life. It’s another stunning example of the teams ongoing aim to turnaround the decline of traditional building craft skill, with repairs to the wood and stone elements being carried out with local material and craftspeople. Lime for conservation work was burnt on site using chalk from the North Downs; stone and aggregate came from Maidstone’s Hermitage ragstone quarry. The impressively crowned and charmingly irregular Kent peg-tiled roof was provided by a local roofing firm and specialist manufacturers, who replaced damaged tiles with new handmade clay ones. The brickwork was conserved by Lynn Mathiasat, known for their work at Hampton Court and Chequers, while the conservation team from Owlsworth IJP, led by mason-turned-site-manager Jim Whitbread, under the direction of architect Mal Fryer were central to the entire process.

Given that around a fifth of the UK’s housing stock is classified as historic (pre-1919), and more often than not, made using stone, this project offers a shining light in how older buildings can be beautifully restored and given a new lease of life.

East Yorkshire-based stone fabrication tooling company, Stonegate Precision Tooling Ltd, have made senior structural changes within the business as they look to capitalise on growth opportunities in the UK, Europe and USA. At senior executive level, former Managing Director, Graham Hazell, will move to the newly-created role of Chief Executive of Operations, while Commercial Manager, Clayton Worsley will take on the role of Managing Director.

In further changes, the business announced the addition of a new Head of Operations. Mark Dennis joins Stonegate from F.Jones Cleveland t/a Gemini. As the company looks to streamline its operational and technical teams, the recruitment of a new Head of Operations will be bolstered by the support of new Technical Team leader, Duncan Collie, who has been with the business for over five years.

New Managing Director, Clayton Worsley commented:
“Over the past two years, we have looked to build on our position as UK market leaders with stone fabrication tooling and solutions, as well as capitalising on previously identified opportunities in newer markets in the United States and Europe. Mark joins us with over 25 years of experience in the stone industry, and his specialism in Operations will allow us to elevate our service and support to customers both here and abroad.
Duncan has been a vital part of our growth to where we are in the UK, and his elevation to this new role will allow him to further optimise processes within the technical team, delivering the ultimate level of service to our customers.”

The stone and hard surfaces sector in the UK is undergoing a significant transformation, shaped by growing demand for sustainable materials, heightened regulatory scrutiny, and a renewed focus on modern applications of both natural and engineered stone. In the past two weeks, a series of developments, ranging from industry relaunches to health concerns, have underscored the sector’s evolving importance within the wider built environment.

A key milestone is the recent announcement of the relaunch of the Stone Show and Hard Surfaces, now set to co-locate with UK Construction Week in 2026. This move places stone and surface technologies at the heart of the UK's largest construction event, reflecting growing recognition of their strategic role in delivering on net zero, safety, and design quality. The integration is also timely, as developers, architects, and local authorities increasingly look for practical, low-carbon materials to meet tightening environmental standards. In this context, stone, long viewed as a traditional material, is being rediscovered for its resilience, thermal mass, and low embodied carbon when sourced responsibly.

One area gaining particular traction is the use of massive-precut stone. This method involves large, pre-dimensioned blocks being craned into place with minimal mortar, allowing for rapid assembly and high structural integrity. While historically associated with heritage buildings, the method is now being explored for modern housing, office, and civic projects in the UK, especially where fire resistance and lifecycle performance are critical. As the industry responds to stricter carbon targets, the simplicity and durability of load-bearing stone offer a compelling alternative to conventional steel and concrete systems, if cost barriers can be addressed through scale and innovation.

Alongside this revival in natural stone, engineered stone remains a major part of the UK interiors and surfaces market, particularly for kitchens, bathrooms, and commercial finishes. However, it is facing intense scrutiny due to a growing health and safety crisis. In recent weeks, reports have confirmed multiple cases of silicosis in UK workers handling quartz-based surfaces, leading to renewed calls for tighter regulation. A number of fabricators have already introduced bans on high-silica products, and the Health and Safety Executive (HSE) is under pressure to follow Australia’s lead in imposing a full prohibition on certain engineered stone types. The implications for UK suppliers are substantial: dust control measures, wet cutting systems, and strict PPE protocols are now essential, not optional, for businesses wishing to remain compliant and protect their workforce.

The industry is also seeing renewed investment in UK-sourced materials and fabrication innovation. Smaller quarries are reviving lesser-used native stones, while workshops are adopting CNC and digital tooling to improve precision and reduce waste. This resurgence of interest in local sourcing aligns with broader government priorities on regional development, heritage conservation, and net zero delivery.

In summary, the UK’s stone and hard surfaces sector stands at a pivotal moment. Those who can balance design quality with environmental responsibility and regulatory compliance are well-positioned to lead. As market conditions evolve, stone is no longer just a finish, it’s a future-facing material redefining how Britain builds.

The final 2024 statistics processed by the CONFINDUSTRIA MARMOMACCHINE Studies Center showed a double-digit downturn in exports of Italian technologies for extracting and processing natural stones, after average annual growth of more than 7% in the three years post-pandemic. Last year the foreign sales of the Italian techno-stone industry – which account for some 75% of the sector’s total revenue – in fact decreased in value by 14% from 2023, going from 1,127.3 to 969.4 million euros.

Negatively influencing export performance was the heavy drop in orders from some of the sector’s main reference buyers, especially the United States – always the top market for stone-working machinery, installations, equipment and tools Made in Italy – whose 2024 imports lessened by 22.5%, to worth of 137.5 million euros. Turkey rose to second place in buyer ranking (+7.1%, to 68.6 million) and France took third (+24.6%, to 58.3 million).

As for the rest of the top ten importers of stone technologies Made in Italy, purchases by the United Kingdom held steady (+7.6%, to 42.9 million) as did Brazil’s (+3.6%, to 30.4 million), while unfortunately there was a decided downturn in sales to other leading European and North American markets: Spain (-19.5%, to 53.1 million), Canada (-12.4%, to 52.5 million), Germany (-24%, to 42.2 million), Poland (-23.9%, to 31.9 million) and Portugal (-13.8%, to 31.2 million).
