The site locates in the center of the town with 300,000 habitants and, since it is surrounded by the buildings, it is impossible to see the scenery. The region is one of the regiones with heaviest snow, at maximum 3 meters depth.
concept of design
In the site, the cleaning factory of the family buisiness is left. Due to the building regulations that prohibit to connects the old building with the new construction to avoid the problem in the earthquake, both buildings are separated. Between both buildings, the passage as a connection space is planned and is covered with big eaves that avoids the heavy snow.
The main space of the house is the 1st floor in consideration with the old grandparents and, on the first floor is a big loft.
The big loft with large windows connects house in the various phase.
The first is a loft as a storage space that is a memory of the family. The second is a space from that each room on the 1st floor is taken via openings in the ceiling at the heavy snow season. The third is that the family is softly connected according to transmitting the sign of each room via the opening of the ceiling.
On the ceiling above the loft, the lights of each room that leaks from the openings are reflected and the sound of the activity is transmitted dimly. Family's sign mixes indirectly at the height of the loft, and a new type's communication that is different from the usual house with private room or the house of one big room type generates. The sign is also overlapped with the sign of the family on the time according to the things put on the loft.
