This gorgeous monolithic house in Portugal, designed by Filipe Saraiva Arquitectos, uses modular design to stay true to the simplicity of a child’s drawing of a house. Its geometry and materials not only reflect the archetypal image of a home– they also allow for optimal energy performance and lower maintenance costs.

The house sits on a sloping piece of farmland in Ourém, Portugal, with a difference in height of approximately 15 feet (4.5 meters) from one end to the other. It is surrounded by natural landscape and overlooks the historic Castle of Ourém.

The design of the residence mimics a child’s drawing of a house, composed of five lines that represent walls and roof, while rectangular shapes represent doors and windows. In line with this simplicity, the main approach to the construction is based on prefabricated elements such as black concrete panels.

The black concrete panels not only help the project blend into the surroundings, but it also reduce maintenance costs.
