Extension of a home addressing the seafront at Clontarf. The previous alterations and extensions left the large house with a series of poorly lit and poorly connected rooms, the living spaces being disconnected from the north facing rear garden. One feature that the clients were keen to celebrate was an original stone wall that defines the long and narrow garden. The existing alterations were removed and a new north facing rear extension was inserted, designed to maximise daylight using clerestory glazing and high-level mirrors. Internally, the cantilevered form is carved out to create a high-level light box and planter, echoing the external planting that has formed in the rustications of the old stone garden wall. The glazing addressing the wall not only places the stone wall at the heart of the home but gives a feeling of width and generosity of space which was previously absent. Externally the cantilever structure helps frame the existing wall while providing a covered seating area. The extension is clad in a charred timber which is complemented by dark internal panelling which links the old and new as well as the internal and external materials. Timber panelling is also reintroduced into the existing house to create a welcoming hallway and a contrasting dark green snug at the heart of the house.
