Sliding House – Suffolk, England

This traditional farmhouse was created by London-based dRRM Architects with one major mechanical surprise. The 20-ton outer shell of this home can be retracted in six minutes, revealing a second, mostly glass, inner shell. Power comes from four 12-volt batteries that run a motor that pulls small wheels, built into the timber shell, along an old set of railroad tracks. This feature gives the owners control over how the house interacts with the surrounding environment, allowing them to make adjustments as seasonal temperatures and light cycles change.
