North-oriented duplex apartment located in a housing block in the upper side of Barcelona. In order to maximize the incoming light, more windows were added in the façade and 2nd floor slab was partially demolished, creating a new living room with a height of almost 6 meters. While the common programme and the parents’ bedroom are located on the ground floor, the first floor is used for the children: two bedrooms, a shared bathroom and the study room, open to the double space of the living room.

We decided to use materials with a light colour to reinforce the light reflection in some areas and to reverse the lack of natural light. The use of the same tropical wood on the floor for the inside and the outside spaces allows creating continuity on the horizontal plane, from the interior to the terrace. On the vertical plane, white walls and pale yellow stoneware glazed tiles are used. The staircase, the balcony and all furniture elements are made in reticular sheet in order to make them more transparent and facilitate the light entrance in every corner of the house.
