House Extension in Killeen Road, Dublin

Killeen Road Extension

The project brief was to renovate and extend the existing protected structure and to provide a high quality open plan living space.


The main house had survived from the late 19th Century with its exterior and interior spaces relatively unaltered. The original windows, doors, staircase, joinery and four cast iron fireplaces remained intact in this house. These were all protected and refurbished during the build. Remedial works were required to the internal lath and lime walls and ceilings, which were carried out in line with conservation guidelines.

Aesthetically, the extension was designed so that it stood on its own as a contemporary element and thus respects the integrity of the existing house. Externally the glazed light-well creates a visual and physical break between the old and the new and it maximises the sunlight coming from the south and flood the light down into the space below to create light filled living spaces. The new extension is wrapped in a cedar cladding softening the impact the extension has on it’s surrounds. A light well was designed between the first floor bedroom and living area below. The novel feature adds an element for fun and surprise to the house.
