Godwit House
Download
as PDF Godwit House is a one-off house on the edge of Warkworth, Northumberland, designed as a response to both the client and the place.The clients life is captured by creating places for her collection of objects picked up through work and travel. The place is captured in the orientation of windows to key views and the materials which are familiar to the agricultural structures found locally.Bedrooms are on the ground floor, clustered around a courtyard garden, the upper floor is a large living, kitchen and dining space with windows splayed to the views across the Coquet estuary.Materials are low in embodied carbon and the house needs very little energy to heat, it also generates electricity through a PV array on the roof. The project increases local biodiversity, with a green roof, rainwater harvesting and a pond to accommodate visiting wildlife.The house is built from high quality materials, it achieved exceptional airtightness and is a certified Passivhaus.
