Channeling Mother Nature into built form, Mexican architect Javier Senosiain designed a peanut-shaped bespoke home with nary a straight line in sight. Appropriately named Casa Orgánica (or Organic House), the home stands out from its suburban surroundings near Mexico City with its curvaceous shape, hobbit-like entryway and a semi-submerged construction. The home, which was built in 1984 and expanded upon a few years later, is the first organic architecture project by Senosiain.

Spanning an area of 1,873 square feet, the Organic House was constructed with a rounded rebar skeleton filled with mortar, coated with sprayed polyurethane for insulation and waterproofing and covered in grass to disguise the building as a green dune that blends into the rolling lawn landscape. Taking inspiration from the shape of a peanut shell, Senosiain organized the home as two ovate spaces — one for the living room, dining area and kitchen and the other for the bedroom and bathroom — unified by a curved hallway.

The entrance is attached to the living area and marked by a hobbit-like round door framed by a dense fringe of foliage. The interior feels distinctly cavernous with its rounded surfaces. Yet despite the cave-like, semi-underground interior, the home is full of light thanks to the insertion of large, curved windows that frame a variety of outdoor views.

“The original concept is defined in two large spaces: one day and one night, looking for the feeling that inside the person will enter the land, that was aware of the uniqueness of this space without losing integration with the exterior green areas,” Senosiain said. “The green dune is the envelope of the interior volume that is almost invisible. From the outside we only see grass, shrubs, trees and flowers. Walking on the garden is walking on the roof of the house without realizing it.”
