Project Overview
Scope of Works
The building’s low-profile form and richly textured concrete echo the local sandstone geology. Using locally sourced aggregates and carefully layered, pigmented in situ concrete, the walls capture the earthy tones and strata of the surrounding landscape. Extensive material testing ensured a finish that will weather beautifully over time, while a reduced-cement mix significantly lowered the building’s environmental impact.
Designed with sustainability at its core, The Weston is naturally ventilated, uses low-energy environmental systems and incorporates innovative humidity control within its concrete structure, delivering a robust, future-ready gallery that quietly supports the artworks within.
Challenges & Our Approach
Challenge: Maintaining stable humidity for sensitive artworks
The gallery required precise control of temperature and humidity to protect sensitive artworks, while reducing reliance on energy-intensive mechanical systems.
Solution: Pioneering humidity-buffering system
To address this, the gallery adopted an innovative humidity control strategy integrating heating, ventilation and heat recovery with a buffer of 10,000 unfired clay bricks.
The bricks naturally absorb excess moisture when humidity levels are high and release it when levels drop, helping to stabilise both temperature and humidity and create favourable environmental conditions for the collection.
The unique structure, constructed by William Birch, earned the 2018 York Guild of Building Craftsmanship Award and was only the second of its kind to be built in the UK at the time.
Sustainability
The LED lighting includes daylight compensation and occupancy detection to further reduce energy loads. To maintain comfortable conditions, solar control glazing and a sedum roof help reduce summertime overheating, in conjunction with natural ventilation to the café through glazed openings and roof lights. Rainwater runoff is retained on site and runs to a swale, improving local biodiversity and reducing flooding risk.

Outcome
The Weston seamlessly integrates into the park’s rolling landscape, providing a calm and inviting entrance while completing the visitor journey.
The building’s low-profile, textured concrete responds to local geology, achieving a durable, weathering façade with reduced environmental impact.
With naturally ventilated, low-energy systems and innovative humidity control, the gallery offers a sustainable, future-ready environment that protects the artworks and enhances the visitor experience, demonstrating a sensitive balance between architectural presence, environmental performance, and landscape integration.
