This project involved the extension to the rear of a two storey semi-detached period house with a long garden plot, the majority of which occurs at a half level above the existing ground floor. Existing brick lined steps, paths and planted terraces lead from a lower court to the upper garden. The house’s existing two storey annex was partly demolished/ reduced down to the half landing level to accommodate the new extension.
The extension takes the form of natural slate clad, prefabricated and preinsulated, structural timber framed roof and walls,as a continuation of the roof of the house, that pitch to form the complete enclosure and volume of the extension. This slate storey sits on a sand blasted, in-situ reinforced concrete slab, which partially cantilever’s over the garden. The Sapele lined openings, with mirror coated low emissivity double glazing result from and emphasize the form of the slate storey, creating a separation from the existing house, a view to the spire of Chapelizod church from the dining area and views of and access to the garden and the Magnolia tree. Roof lights provide a variance in day lighting and separation of the structure from existing adjoining conditions. Artificial lighting is provided by 35W slim line fluorescent tubing with integrated ballast and follows the pitch/angles of the volume. The fitted out storage units create / screen the bathroom, utility, kitchen and dining areas and are set at height that allows the overall volume to be perceived.
