The owners of this residential protected structure required additional ‘family orientated’ living space within their Georgian terrace home, situated in Dun Laoghaire, Co. Dublin. Consequently, the existing dilapidated lower ground floor was completely renovated, and a single storey rear extension added, providing a spacious and bright open plan living/kitchen and dining area, along with a separate playroom. Working with older buildings such as this requires thoughtful planning and attention to detail. The interior is contemporary, open and bright; however the existing historic fabric has also been respected.
