Standing in a row of traditional townhouses is the long and narrow House in Lisbon. Designed by ARX Portugal, this modern beauty is comprised of two main materials: limestone and concrete. The front facade is enveloped in limestone, one of the most common materials used in Lisbon. The limestone is set in a modern design yet still links the home with its conventional neighbors. The rear of the house focuses on the outdoors: giant windows and several balconies overlook a secluded backyard garden.

Almost the entire interior of the house is made of raw concrete. This material twists and turns to define the walls, floors, stairs, and furniture. The house is arranged with the public areas on the lower floors and the more private rooms above. An outdoor refuge is located on the roof: limestone walls hide the user from the street below while a lone tree brings life to the space. Overall, House in Lisbon is a lovely design which uses simple materials to create a harmonious space.
