The moving part of this remarkable sliding building by DRMM is a whopping 50 tons and nearly 100 feet long. Gliding on rails, this enclosing exterior element with its own walls, roof and opening can be adjusted to selectively reveal and conceal spaces within the home.

The sliding roof structure is a steel frame with timber infill. It is also clad in natural larch on the outside with the same red weatherproof membrane underneath. As well as providing shade in the summer, the roof acts as an insulating layer in winter, giving the possibility of solar gain during the day but heat retention at night.”
