The ICF Home


GMJ were commissioned by a private client to construct a new build property in a remote part of rural Wales. The Client of this bespoke project wanted a modern, high performance building with low running costs and intelligent systems embracing future technology whilst ensuring that the building integrated in to the surrounding landscape. The building was to be a 3 bed room home, with open living areas, large glazed areas for natural light and high quality fixtures.

The remote location of the property meant that it had no services available, we therefore had to address the method of construction, the carbon profile of the design and the efficiency of the resulting building, whilst ensuring that the new building was in keeping with the natural beauty of its rural position. The ICF, insulated Concreate Formwork, system was a simple solution that addressed all of the requirements. As an innovative, sustainable, high performance building system, Integraspec ICF enables the fast construction of creative, flexible buildings with low running costs and a long life and the ICF home at Dolwyddelan is an excellent example of this.

With the property totally off grid, no mains gas, water or electric or any possibility of future connections, alternative systems had to be implemented for this state of the art home. The building promotes the use of alternative energy sources. Solar Panels have been installed to the adjacent barn, charging a series of batteries to power the electrical requirements of the property. The combi boiler has been installed with a buffer vessel to maximise efficiency. There is a Rehau heat pump to maintain the building circulation without compromising the efficiency of the building.


Energy Efficiency Rating: A+ | Estimated Energy Cost Per Annum: £1200 | Contract Location: Dolwyddelan |
