Minimalist home in the Brazilian countryside is made from mining waste

Brazilian architectural firm Gustavo Penna Arquiteto e Associados (GPA&A) has unveiled a tiny, minimalist home with a small stature that conceals a powerhouse of sustainable design. Located in a former mining region, the architects decided to build the 484-square-foot Sustentable House out of bricks manufactured from mining sludge waste. The family home is also installed with solar panels and a wind turbine to produce energy and heat water. Additionally, the residence is almost completely zero-waste thanks to an integrated waste water treatment system and organic waste incinerator.

The small home is located in the pristine, mountainous area of Ouro Branco, once an important base located on the transportation route from the mines of Minas Gerais to the coast. Paying homage to the region’s history, the architects were able to construct the Sustentable House with bricks made out of the byproducts of mining.

Tucked into an open lot surrounded by forest, the house sits on a small, flat plot of a sloping hill. The volume has a cube-like base topped with a slanted rooftop. The sloped roof was an important factor in protecting the interior from direct sunlight. The roof was also installed with a small solar array that heats water for the residence, although it will eventually power the entire home.

At the front of the building, a wall rises up past the slanted rooftop. The cutout space in this section is outfitted with a wind turbine that generates energy for the home. The design also incorporates an organic waste incinerator that produces energy through hot air and an integrated, state-of-the-art wastewater treatment system that can be used as an additional power system.

All of these sustainable features are wrapped up in one gorgeous design. The two-bedroom house’s brick walls wrap around the exterior and interior, except for the front facade, which is made out of floor-to-ceiling glass panels. The wide glass doors slide open completely, opening up the living room to the great outdoors. This allows the homeowners to enjoy unobstructed views of the mountains and valleys that stretch out across the horizon.
