The proposal was for a two-storey extension to a house in Aghalee.
The client required two bedrooms with a double garage below. A dominant feature was the use of hempcrete in the walls, which is a mixture of Hemp shiv, lime and water, surrounding a timber frame. Other natural building materials were used also such as wood fibre board and sheep’s wool insulation in the roof, clay pellet insulation in floors and natural paint. Natural materials have low embodied energy as well as providing a well-insulated building that is naturally breathable.
