The dwelling is located on the top floor of a multi-family property between party walls with a ground floor and four floors, built at last of the XIX century in the Gracia district of Barcelona. The top floor is set back from the façade plan and, therefore, the dwellings are smaller than those on the lower floors. The support system of the building is made up of load-bearing walls and floor slabs of wooden joists with ceramic laps. As it is a later construction of the rest of the estate. Above the last horizontal roof there is a gable roof of wooden beams from party wall to party wall and a roof of fibre cement boards, covered with sheet metal in a later refurbishment.

To improve the quality of the interior space of the flat, the maximum of partitions will be eliminated, leaving only a living room-kitchen, a bedroom and a bathroom. The position of the bathroom and kitchen will be changed to make the most of the facade of the living room. For all these reasons, some partition walls will be demolished and a new minimal partition will be erected to maximise the space of the hall as much as possible. The ceiling will be made of plasterboard panels, taking advantage of the available heights, which vary a lot between the centre and the facades, but always leaving an air chamber between the roof and the ceiling.

To the south, the gallery is left open as sun protection. The exterior carpentry will be renovated and the gallery will be fitted with traditional exterior roller blinds of light wood, providing solar protection in summer without sacrificing luminosity. The interior carpentry will also be completely new, as will the original flooring, which will be replaced by a new parquet floor and porcelain stoneware in the bathroom..

Hot water is produced by a gas heater and thermal comfort in winter is provided by the warm air produced by a split system. In summer it is hoped that this will be sufficient with the facility to generate cross ventilation and a ceiling fan in the centre of the room, leaving the split unit for peak heat and humidity.
