This glass box extension was installed onto a listed brick home in Hampstead, London as part of a rear refurbishment. The structural glass box was created using low iron structural glass. This ensured that the frameless glass box maintained its clarity and transparency against the listed building. The low iron glass was utilised across the frameless glass walls, roof as well as the structural glass beams.
Due to the listed natural of the building, the connection of the glass box to the brickwork was a highly sensitive area of the project. The brick was not to be covered with plasterboard post installation therefore, the fixings themselves had to form part of the glass box design.
In the end, we worked with the architect to develop a fixing and connection detail with brushed stainless steel brackets and channel work. This ensured that the glass extension was firmly connected to the listing building while creating an attractive combination of glass, brick and stainless steel.
