This single storey extension project was completed on a Grade II listed building in Halse, on the outskirts of Taunton. The scope of work included a large extension using the footprint of an unused courtyard area. Access to the existing courtyard was restricted, which made the extensive groundwork all the more challenging. The extension created a large open plan space by using steel beams, which upon sat a roof constructed of both lead and a specialist triple glazed aluminium system.
