The project involved the conversion of a redundant, concrete water reservoir that was buried in the ground to form a family house. The design allowed for the tank to be partially uncovered and then extended above with a roof form which followed the terrain. The tank form was fully expressed and complemented by the weathered steel eaves fascias. The roof covering was finished in sedum to help blend in with the landscape and encourage local wildlife. By thinking imaginatively about the reuse of an existing structure that would not normally become a house, the team were able to transform the setting and provide a high quality residence for the client.
