Replacing a 1970's bungalow, this new eco house on the edge of a pond in East Meath is inspired by a visit to a Japanese Tea house on the Island of Shikoko; the sense of water within the space, including the reflected light onto the ceilings, brings a sense of serene calm. Even in deep winter the house is peaceful in its setting. A heat pump draws from a submerged array in the pond and a solar cabin oriented due south maximises gains for solar thermal panels allowing the spaces to be oriented square-on-diagonal to the south admitting available sunlight to all spaces, year round. The structure and fabric is eco logical.
