How long does it take to erect the timber frame and at what stage is the house at when the erectors leave site?

The installation of a standard 3/4 bed house will take on average 7-10 working days. When the erectors leave site you will be left with a complete structural shell including wall panels, floors and roof trusses that are braced. The first job for the client to do after the erectors leave site is to bring in the roofing company to felt, batten and tile the roof to make the structure watertight and put a loading on the frame. Various trades can then be brought in to work both inside and outside the structure at the same time.
