Birds-eye photograph of ICF house

Built from scratch using the Nudura ICF system, this home is sunk partially into the surrounding hillside. A roof constructed of Op-Deck, concrete and fibreglass finished with astro-turf helps the building maintain a constant temperature, whatever the weather.

The OpDeck concrete is used as a diaphragm to support the angled beam across the structure. The building sits on insulation and all areas of possible bridging are insulated both internally and externally.

The owners wanted to build a solar energy fed house in Devon’s maritime climate with the aim of zero input for water and space heating. They avoided heat pumps due to their power requirement.

We have delivered an energy efficient, high mass house with internal block walls while 17 tons of floor screed assists in moderating the temperature changes. Both east and west walls are covered with earth which helps maintain a constant temperature of between ten and 12 degrees.

Although the project took five years to complete, the owners Peter and Helen were able to retain full-time jobs while working as Nudura- trained installers in their spare time.

A construction professional himself, Peter said: “We already knew we wanted to build in ICF because of its proven reputation on energy efficiency and comfort levels that it delivers. Our home achieved an SAP A rating of 97 out of 100 and thanks to Nudura’s Sound Reduction Index of 51 the house is so silent, we won’t know if a gale’s raging outside.”
