Window is a private house designed by LADAA and is located in Valencia, Spain. The decision was to make the house in two unique stories allows us to rise and enjoy the views on the main floor without breaking the cornice height. In the same way and using the natural orography of the terrain we achieve that part of the piece which is embedded is totally exterior and can be considered as habitable space and used for guest bedroom and bedroom for the daughter of the family, adding a patio on the main facade as to achieve optimum ventilation and lighting of these rooms. The house appears as a large box in which everything is made of glass and where the indoor-outdoor boundaries are not know, as well as a perfect prism on top with one of the sides totally open, almost deceiving us as it not only harbors edification but also serves to generate outer space, habitable and protected. It is important to mention that the garage entrance is considered as the main entrance or and accordingly the patio which appears in front of this entry is always bathed in the water from the pool and on a garden.
