The Leaf House, a marvelous piece of architecture designed by Mareines + Patalano Arquitetura (Architecture Company in Brazil) and is located in Angra dos Reis, close to Rio de Janeiro, Brazil. The design is quite unique as its inspiration is Indo-Brazilian in nature and this structure is built to neutralize the hot and humid weather of the area it is built in.

This beach home known as The Leaf House is actually covered by a giant roof which is in the shape of various leaves. These leaves cover the enclosed portion of the house and keep it cool.

No corridors are made and inside and outside of the house are fused together. Sliding doors are used those are glazed in order to allow the sea breeze inside the house.

Swimming pool is curvy in shape and it snakes into the house and while it passes below the dining room it converts into a pond having fishes and aquatic plants in it. It extends to the rear “veranda”. Veranda is the resting space having 5 of the Brazilian Indian style hammocks and this space is called “Brazilian Lounge” by the constructors of the house.

The leaf like structure of the roof is made of composite reforestation wood (Eucalyptus) which is capable of covering big areas as in this case 20 meters is the biggest one here and it is quite delicate and soft to the aesthetics. The roof is covered with small reforestation wooden tiles (Pinus Taeda) that has adapted beautifully to the complex surface of the roof. Rain water is also collected through the steel column placed in the center. This water is to be reused in gardening and toilet.
