A-House is a single-family house located on a mews lane in a Victorian suburb of Dublin city. The house is an exploration of diagonal space within an orthogonal form and the possibilities of integrating environmental concerns at a fundamental level.
The site was chosen for its proximity to schools, local shops, recycling facilities and work, allowing a daily life independent of the car or public transport. The house itself is large enough to support a family over a lifetime. Located in the former back garden of a three storey Victorian terraced house, the house is accessed from a lane to the south with the garden to the north.
A concrete tube provides the structural and spatial organisation for A-House, enclosing the public areas of the house. Divided by joinery elements, the tube of space is twisted between ground and first floor to allow a relationship to the garden and daylight from above. This diagonal spatial relationship between the two floors allows a simultaneous experience of all dimensions of the house - length, breadth, height and extending into the surroundings in unexpected diagonal glimpses.
In common with its neighbours, the exterior is restrained, choosing a formal expression of the relationships between internal spaces and elevation. Drawing on the Georgian tradition, windows are floor-to-ceiling allowing daylight to penetrate deep into the plan.
A-House has been designed to achieve an 'A’ Building Energy Rating, with a particular emphasis on the use of passive systems. The concrete exposed internally contains GGBS Portland replacement cement, a low carbon product, and is sandblasted to accentuate the liquid nature of the material and to record the process of construction.
