Background

After working with traditional earth materials in different regions, they established the company in Cornwall around 2010.
Their goal was to combine traditional clay construction knowledge with contemporary architectural and interior design needs.
Products & Features
Interior Clay Plaster
Clayworks produces a range of clay plaster finishes focused on wellbeing, enhancing interior atmosphere.
Their finishes are available in a wide range of colours and can be customized for different project types and scales.
They offer both classic finishes with balanced texture and refined aesthetics, and custom finishes that explore more innovative and expressive surface effects.
Exterior
Clayworks’ exterior finishes combine clay and lime to improve durability in outdoor conditions, offering both classic and custom solutions, including rammed earth finishes, for flexible and high-performance applications.
Custom Clay Finishes
These custom finishes explore unique textures and effects, tailored to meet the specific vision of each project. They emphasize innovation and experimentation, creating distinctive surfaces that enhance both aesthetics and function.
Rammed Earth
Clayworks’ rammed earth finishes reinterpret traditional rammed earth construction, which is typically heavy and difficult to use in urban contexts.
Instead of thick structural walls, they offer a thin 7–10 mm surface layer that replicates the layered appearance of rammed earth.
This makes it a lightweight, customizable, and more accessible solution for contemporary construction.
Projects
Clayworks is used in hospitality, retail, restaurants, commercial and residential projects.
Across these spaces, their clay finishes create warm, tactile environments,
strengthen material identity, and improve indoor comfort.
Retail
Designed in-house and supported by sustainability, interior, and built environment specialists, the COS Flagship store in Mexico combines the country’s rich artisanal craft traditions with more sustainable design. Their rustic interior and exterior finishes draw inspiration from Mexico’s golden cornfields, adding depth, texture, and a strong sense of place.
Commercial Projects
On’s London office uses Clayworks’ rammed earth clay plaster to create a strong, natural material presence within the space.
The hand-applied finish forms a sculptural staircase and layered surfaces inspired by local geology, enhancing both texture and atmosphere.
