Longacres House, designed by Damien Murtagh is a coastal dwelling on the Burrow Peninsula in Portrane, North County Dublin in Ireland. Nearby, a natural bird sanctuary, a marina and an island make up the landscape that is a sand and gravel ridge of salt marshes and dune grasslands.
The client requested that the house be designed as an element that was of the rural and coastal and environment, developed through its form, scale and appearance. An emphasis was placed on daylight, nature, the elements, tangible materials, textures, spatial interaction and energy awareness.
The composition of the house includes a two story spine with two perpendicular arms that form a private courtyard. With so many surface areas exposed to the house surroundings the architect was able to take full advantage of the views offered by the landscape. The social spaces of the ground floor, with full views to the exterior provide daylight and a panorama throughout the year. The layout consists of an open plan with sliding walls that provide flexibility and a playful interaction between the spaces and members of the house.
The palette of the material is of a natural stone quality: exterior dry stone walls, patina copper, slabs of travertine and cedar cladding all of which blend within the palette of the landscape. The home is designed to meet a Grade A Building Energy Rating, the highest as per Ireland rating system for a dwelling. The house incorporates geothermal heating, photovoltaic solar panels and a heat recovery system.
