Located to the west of Madrid, this contemporary horizontal structure is the design of the Spanish practice of Inaqui Carnicero Architects. Completed over a five year period, the two semi-detached homes are built as one, although not symmetrical, they share many design features as well as having a single electrical system. The project was built on a budget with a view to sustainability both during the construction period in the future maintenance of the homes.

The two huge granite rocks which pre-existed on the site have been incorporated, structurally and as part of the entrance, creating a striking contrast between the modern concrete and the organic ruggedness of the rocks. Throughout the interior the concrete has been left exposed to form a backdrop for unusual feature of the double height bookcase and the elegant lines of the furniture, combining design classics such as the Barcelona chairs and artichoke pendant with the bespoke pieces with linear lines which link the spaces. Light polished limestone floors ensure the coolness of the interior in the summer months and underfloor heating warm the large spaces during the winter.

The main volumes of the building are above and below the panoramic view of the skyline through the elongated glass expanse which connects the two homes which could easily become one single dwelling perfectly designed for a southern climate.
