Complete refurbishment of a 250 m2 house on the fourth floor of a listed building in the Chamberí neighborhood of Madrid. The house is demolished in its entirety except for the load-bearing walls and the new program requirements are adapted to the existing openings in said walls, as well as to the damp cores of the house. The kitchen is located in a central position and is designed as an element of passage and separator between the public and the most private areas of the house. All the old moldings as well as the wood windows are respected and restored. The selected materials and furniture seek to renew the space without losing its essence and character.
