São Paolo-based firm Steck Arquitetura has just unveiled the Julieta House, a concrete home that spans nearly 7,000 square feet.

Located in the city of Piracicaba, the house is comprised of a concrete shell that provides a strong thermal envelope along with a bevy of sustainable features such as solar power to help the home reduce its energy needs to a bare minimum.

Surrounded by a low-lying concrete wall, the three-story home is located on a sloped lot that creates extra space for its large volume. The partially-embedded ground floor houses the garage, storage space and maintenance equipment.

The main living area is located on the first floor, where high ceilings with sunken spaces add a sense of whimsy to the atmosphere. The main social areas, along with the private bedrooms, all boast a modern, minimalist design. Sparse furnishings bring out the warm palette of wood and concrete that is further enhanced by an abundance of natural light.
