A modest, low-budget rural home in County Down, Northern Ireland, has been named House of the Year 2019 by the Royal Institute of British Architects, beating out a stellar shortlist of creative builds as featured on Grand Designs House of the Year.

The single-storey house, known as House Lessans, cost just £1,425 per square meter to build, a total of £335,000. To do this architect Kieran McGonigle of McGonigle McGrath used rough, low-cost materials such as concrete bricks, finished to a domestic standard. He also kept the floor plan simple while maximising the sense of space and light with high ceilings and huge fixed windows, a cheaper alternative to bifold doors.

House Lessans consists of two perpendicular blocks overlooking a sheltered courtyard. Built on the site of a former farmstead, it takes its cues from a neighbouring shed, using white rendered concrete walls and zinc pitched roofs.

Inside there’s an open-plan kitchen/dining/living room, as well as three bedrooms and one bathroom. A mezzanine study has been fitted in above a pantry. Pared back interiors follow a soft grey colour scheme. Grey walls follow a consistent height throughout the house, tying everything together, with roof spaces painted a reflective white.
