T he brief energy was to efficient build home an which was in keeping with the local surroundings. It was important to Mr and Mrs Orr to build a property that encompassed traditional values with a modern twist as the plot sits beside farmland. Budget was also a key factor for the couple, they wanted to build a house within their budget but with scope for expansion in the future. The property is situated in a rural location at Lomond Muir Farm, Wester Balgedie, Kinross-shire. DESIGN The clients brief was to build an energy efficient home within their budget but also to allow scope for expansion in the future. It was also important for the design to be in keeping with the rural location, however they did not want to house to be too traditional. As energy efficiency was a high priority for the client, we decided to use the Kingspan TEK SIPs system. The walls and roof of the property is constructed using structural insulated panels (SIPs) connected with a unique jointing system that minimises the amount of air that can pass through the joints. To allow for expansion in the future, the house is designed and constructed as 1.5 storey shell. However, to keep within the clients’ budget, at the moment the house only has 3-bedroom ground floor accommodation measuring 170m2. In the future there is scope for creating a further 80m2 first floor accommodation, which due to the Kingspan TEK roofing system will allow the rooms to be fully vaulted, creating a unique living space. For the exterior of the property, natural materials such as slate roofing and sandstone cladding were used alongside, wet-dash roughcast and maintenance free windows & weatherboarding. Due to the Kingspan TEK, SIPs system, the dwelling is highly insulated with an excellent airtightness level and incorporates underfloor heating, a wood burning stove & a solar thermal roof installation to supplement the energy demand for hot water. Passive solar gain is maximised with large South facing windows. All this combined with an MVHR system has allowed THCL to produce an A-Rated energy efficient house.
