Roof House is a minimalist house located in Fredensborg, Denmark, designed by LETH & GORI. The existing house is occupied by a family with three children and the specific needs of the family formed the basis of the project. Planning restrictions on the site called for a careful and minimal approach and this lead to the idea of extending the house by upwards by adding a series of roof buildings. This way the project adds a new bedroom and a workspace as well as skylights and sleeping platforms for all the childrens bedrooms. In addition the project includes redesign of the facade making it more energy efficient and adding new and larger openings. The roof construction and skylights is wrapped in asphalt roll roofing.
