The house is situated on a quiet plot within the orderly urban development of Santo Domingo in Madrid where a compact existing housing occupying the center of the plot was the starting point, and that for economy is decided to use the existing basement which was decisive for the location of the new house. The new proposal, more extended than the compact original dwelling, clearly organizes the parcel into two areas: the first and most representative, geared towards access, and the second, more private and fragmented volumetry, endowed with activities such as swimming pool, tennis games, trampoline, outdoor dining, garden, etc..
