Glass Extension to Listed Building in Somerset

This contemporary glass extension was added to the Grade II listed building in Somerset to help extend the living areas and connect the interior spaces to the spacious landscaped gardens.

The architect’s brief from the clients was to remove the old glass lean-to structure and replace it with a modern glass extension that was useable year round. The new glass extension provides a central and level route from the living areas to the garden outside.

With the brief for lots of light and an enhanced connection to the outdoors, the architects specified our minimally framed sliding glass door to create the moving glass walls to the rear of the extension. The glass extension meet son a corner with a large frameless pane of structural glazing which creates a glass wall, aiding with maximising natural light.

By using large, glazed walls for the listed building extension, the brick walls to the listing building and external flint garden wall appear to wrap around the glass extension. The use of glass to create the extension to the listed building was supported by Wiltshire Council who worked with the architects during the pre-planning application.

The use of ultra slim sliding glass doors to create the glass walls of the extension both satisfied the requirements of the planning officers but also satisfied the client’s requirements for natural light and a better connection to the gardens.

Smooth limestone floors flow from the internal living space within the glass extension to the external flooring outside, thus connecting these spaces even further. As the glass sliding doors provide a floor to ceiling glass elevation (with no visible framing at the base) the glass allows the interior space to unfold to the garden – even when the weather requires the doors to be closed.

The glass extension is south facing so the flat roof of the extension was designed with an overhang for solar protection. The overhang provides shading to the glass walls of the extension and minimises the solar gain. This was then covered with dark aluminium pressings to match the framing of the minimal sliding doors.

The building is Grade II listed detached house which was built in the early 18th century. It was formally the estate office for the local manor house and estate which was restructured in the 1980’s. The estate house remains and has been renovated throughout the years. The new glass extension was designed to be sympathetic to its listed nature and the traditional architecture of the building and its surroundings.

The listed glass extension is located in Somerset and managed by our dedicated regional team.
