Clay finds new purpose in Saudi Arabia’s sustainable construction boom

 

Clay emerges as a preferred finishing material for luxury landmarks in Saudi Arabia  

As Saudi Arabia accelerates one of the world’s largest construction programs under Vision 2030, an ancient building material is making a remarkable comeback. Clay—once the foundation of traditional Saudi architecture—is re-emerging as a preferred finishing material for luxury hotels, cultural landmarks and residential developments, offering a blend of sustainability, heritage and modern design.

The revival reflects a growing shift across the Kingdom’s construction sector, where developers are increasingly balancing rapid urban expansion with environmental responsibility. Alongside mega and giga projects, architects are embracing natural materials that reduce carbon emissions while preserving Saudi Arabia’s architectural identity.

For centuries, clay played a vital role in shaping the Kingdom’s built environment. Thick earthen walls naturally regulated indoor temperatures and humidity, creating comfortable living spaces suited to the desert climate long before modern cooling systems became commonplace. Today, advances in engineering and construction techniques are allowing those traditional principles to be integrated into contemporary buildings.

From the restoration of historic mud-brick neighborhoods to flagship developments such as Diriyah, Red Sea Global destinations and the Tuwaiq Heritage Tower, clay is increasingly viewed as both a cultural asset and a practical solution for sustainable construction. Designers are adapting traditional earth-based materials to meet modern performance standards while maintaining the distinctive character of Saudi architecture.

The environmental advantages are substantial. Unlike cement- and acrylic-based finishes, natural clay plasters require significantly less energy to manufacture because they are dried rather than fired or chemically processed. They also contain little to no volatile organic compounds (VOCs), contributing to healthier indoor air quality, while their natural ability to absorb and release moisture helps regulate humidity inside buildings.

Perhaps most significantly, clay supports efforts to reduce embodied carbon—the greenhouse gas emissions generated during the extraction, manufacturing, transportation and installation of construction materials—an increasingly important consideration as Saudi Arabia advances one of the world's largest development pipelines.

Majed Al-Qatari, a Saudi sustainability expert, believes the Kingdom's unprecedented construction activity presents an opportunity to rethink not only how buildings are designed, but also the materials used to build them.

"Saudi Arabia's boom in construction paves the way for a much-needed consideration of not just construction volume, but also construction materials," he said.

According to Al-Qatari, natural clay materials can significantly reduce embodied carbon due to their lower processing requirements, absence of petrochemical binders and potential for local sourcing, which minimizes transportation-related emissions while supporting circular economy principles.

He added that clay offers benefits beyond emissions reduction.

"Clay finishes naturally regulate indoor humidity, improve thermal comfort and are free from volatile organic compounds, creating healthier indoor environments," he said. "While clay is not intended to replace structural materials such as concrete or steel, it has significant potential as a scalable finishing material that combines traditional building knowledge with modern engineering."

Research also indicates that clay finishes generally have lower embodied carbon than conventional acrylic or cement-based coatings while requiring less maintenance over a building's lifecycle. Their breathable, repairable and recyclable properties further strengthen their environmental credentials.

Growing industry interest was recently highlighted in Riyadh, where Conmarble Atelier hosted British natural plaster manufacturer Clayworks for an interactive workshop that brought together architects, designers and construction professionals to explore traditional clay plastering techniques. Participants experienced firsthand how natural clay finishes can be applied to create a wide range of textures suited to contemporary interiors.

For Clayworks, the event reflected more than product promotion—it underscored Saudi Arabia's emergence as a rapidly expanding market for sustainable building materials.

"We started getting lots of specifications from architects and designers in Saudi Arabia about five years ago," said James Bryce, the company's representative for Saudi Arabia and the wider GCC. "The volume kept increasing to the point that we couldn't ignore it anymore, which is why we needed to be present here and tailor our designs to Saudi Arabia."

The company now supplies natural clay finishes for projects including developments by Red Sea Global and Diriyah, where designers are incorporating the material into luxury hotels, cultural venues and high-end residential communities.

Bryce believes the Kingdom's longstanding relationship with earth-based architecture gives Saudi Arabia a unique advantage in adopting natural construction materials.

"Saudi Arabia has a very strong tradition and relationship with earth and natural materials," he said. "Where we can show designs that are sensitive to that tradition while also making them contemporary for the future, we've found the right balance."

Unlike conventional paints, Clayworks' products are made entirely from natural clay, with different textures and finishes created through specialized application techniques rather than chemical alterations to the material itself. This versatility allows designers to achieve everything from smooth minimalist interiors to richly textured feature walls and moisture-resistant finishes using the same natural base.

As Saudi Arabia continues investing in tourism destinations, luxury hospitality, residential communities and cultural landmarks, demand for environmentally responsible construction materials is expected to rise. In reviving one of its oldest building traditions, the Kingdom is demonstrating how heritage can inform innovation—transforming clay from a material of the past into a cornerstone of sustainable architecture for the future.
