Portuguese firm Atelier 1111 has unveiled a gorgeous home designed to strategically blend into the rural region of Grândola in southern Portugal. The Cottage House is an angular design embedded into a small hillside, putting part of the home underneath the arid landscape. This technique provides the house with a strong thermal envelope, which — along with additional passive cooling strategies such as a green roof and thickened stone walls — boosts energy efficiency. Using the idyllic setting as inspiration for the design, the exterior of the home is clad in a rammed concrete, which gives the exterior a textured, neutral color that blends in with the arid soil.
