Construction racing ahead on ultra low energy home

Mill Race, Wiltshire

WDA are proud to be involved with this exciting energy efficient form of construction for the new house at Mill Race, Donhead St Andrew in Wiltshire.


The client has successfully built with this material on a previous Western Design house (Hers n Mine). BecoWallForm system was chosen because it is so energy efficient that additional heat required from the ground source heat pump is minimal.


The construction process is quick, tidy and precise. BecoWallForm system consists of large hollow lightweight blocks components that lock together without intermediate bedding materials to provide a cavity into which concrete is poured. Once set, the concrete becomes a high strength structure and the formwork remains in place as thermal insulation. The wall is so strong that major beams can be placed directly onto the wall without padstones.

Go to project

This house is being built by only two people due to the simplicity of construction. Stone masons follow on with an external skin of Shaftesbuy Greensand stone on the main house. The garage annex will be clad with timber.
