This project is an extensive retrofit and extension to a 200-year cottage stone structure (originally a cowshed) as part of a larger regeneration of a larger estate. The stairs are moved out of the original cottage into a new extension with a grass roof. A small timber dormer (as a small shed) covers the stairs. Removing the stairs from the cottage creates space for an extra bedroom. The entrance also becomes a small viewing point over the landscape and to the other side of the cottage. The cottage has been detailed according to Passiv Haus standards.
