The site was an existing derelict rendered house at the end of a brick terrace in Drumcondra, Dublin. The program was to renovate the existing house while extending to the rear. Due to the house’s location at the end of the terrace with a laneway running to the North side, we had the unique opportunity to allow a soft North light into the length of the entire extension above the height of the existing lane wall. The design for the extension developed out of this desire to cantilever the upper floor to allow for a continuous window over this wall. We were interested in developing an expressive tectonic solution to this structural idea.
The structure is one of frame and infill with a structural frame of black stained glulam timber and a brick infill to match the neighbouring terrace. The structure is expressed externally and internally with the black bands carrying across walls and floor creating a spatial complexity of layered frames. The structural dimensions are derived from the size and proportion of the existing reception rooms creating a rhythm of repeating volumes from house to extension to garden. The building is detailed to be expressive of its construction with finger jointed timber, exposed steel flashing, and corners which reveal the brick’s usage as thin infill screen rather than load bearing masonry.
