Conservation of The Mercury Building, Weston.

Mendip Stonemasons were commissioned to restore the structurally compromised stone elements of the historic Grade II listed Mercury Building in Weston-super-Mare. Due to years of harsh coastal weathering, the gables and other exposed stone features had deteriorated significantly. Our work involved the careful dismantling and complete rebuilding of the gables in new stone, stabilising them with hidden stainless reinforcement, and completing targeted stone replacements throughout the façade and tower. Combined with protective limewashing and replacement of damaged balustrades, this restoration ensures the Mercury Building continues to stand safely and proudly as a landmark of historic craftsmanship and civic heritage.

Goals & Requirements

Restore the structurally compromised gables

We aimed to rebuild the front and rear gables using carefully selected new stone, replicating the original design while ensuring long-term stability. This approach preserves both the structural integrity and historic appearance of this landmark building.

Stainless steel straps and pins were integrated discreetly to tie the structure together and strengthen vulnerable areas. The goal was to provide robust support without compromising the visual authenticity of the historic masonry.

All fractured or weather-damaged stones throughout the tower and balustrades were replaced with matching materials. This ensures the building remains safe, durable, and visually consistent with its original architectural style.

Every element was restored with careful attention to detail, faithfully following Hans Price’s original Dutch Baroque design. This allows the Mercury Building to maintain its heritage significance while meeting modern safety standards.

Limewash and other protective finishes were applied to shield the stone from salt-laden winds and coastal rain. This preventative measure extends the lifespan of the restoration and helps maintain the building’s appearance over time.

Project Challenges

Severe deterioration of gables and tower stonework

The gables and upper tower had become loose, fractured, and crumbly due to decades of exposure. This made careful dismantling and rebuilding essential to prevent further damage.

Salt-laden winds and constant moisture from the nearby seafront accelerated stone decay. Working in these conditions required protective measures and weather-conscious scheduling to ensure quality results.

The building’s Grade II listing and historic Dutch Baroque style demanded that all repairs closely match original materials and detailing. Balancing this with structural reinforcement added complexity to the restoration.

Rebuilding the gables and replacing upper tower stones required precision at height, with careful lifting and positioning of heavy stone blocks. Safety and accuracy were paramount throughout the project.

Integrating stainless steel straps, pins, and lime bedding had to be done discreetly so as not to detract from the building’s historic appearance. Every intervention needed to provide long-term stability while remaining visually sympathetic to the original architecture.
