The Kylemore House Strategic Housing Development (LRD) scheme received planning for a 259-unit scheme, centered around the historic Kylemore House (Protected Structure) in Killiney, Co. Dublin, with Part V provision to the front of the site. It was an extremely challenging site to achieve compliance with BRE 209 Daylight/Sunlight requirements whilst maintaining existing mature trees throughout the site, and Metec undertook the following roles in this high-density development – Daylight/Sunlight Assessment, Building Lifecycle Assessment, Energy/Part L compliance, Site Lighting (Bat-sensitive) and Mechanical & Electrical Plant Space provision.


Achieving the Client’s requirement for compliance with BRE 209 calculation criteria for a minimum 96% of all Living/Kitchen/Dining and Bedrooms whilst maintaining trees on this mature site was an incredible challenge for Metec and the Architect. We worked closely with the Architect, suggesting changes to layouts, depths of rooms and aperture sizing where required to achieve this challenging target.


The project was subsequently the focus of a Judicial Review, however none of the points used for the Judicial Review related to Sunlight/Daylight which had been the case for most previous Judicial Reviews.
