4.5.4 The private house
The private house is located at the innermost point of the project site, being also the most private space; the building is thought to be the home of the family that will take administrate the area, taking care of the greenery and managing hostel and multifunctional building.
The private house is composed of a courtyard-building system very similar to that of the hostel, therefore the 120 m2 open courtyard and the 42 m2 veranda placed along the entire south side are again present, thus becoming an additional space external; in this case the morphology of the court varies.
The courtyard is designed to have two functions: additional outdoor space and garden (cultivable or not), usable by tenants.
The flat roof is also in this case designed as a green roof, creating together with the garden space of the courtyard a system of cultivable green; on the roof there are also repaired common areas for users, which in case of need can be converted into green space.
The private house, like the other two buildings, has the same structure and the same envelope, but inside it is divided into three zones, such as the hostel:
day-zone, service-zone and night-zone.
The day-zone is arranged along the south side of the building, and being the best exposed side, it includes the most used areas: the kitchen of 17.4 m2, the living room of 23 m2 and the study of 17.4 m2. In this case, in winter it

is possible in winter it is possible to make maximum use of the solar gains, which allow to have higher temperature values and daylight factors inside.
The day-zone has the widest fixtures positioned on the south side, and are 3.20 m wide, 4.10 m and 3.20 m; their height is 2.70 meters. Then it has two symmetrical entrances to each other, one on the east side in the kitchen and one on the west side in the studio, 1.00 m wide and 2.70 m high.
The service-zone is located in the central part of the building and consists of all the service areas; starting from the east side: a bathroom of 4.15 m2, an aisle of 4.2 m2, a storage room of 5.07 m2, an additional working space of 7.83 m2, the second bathroom of 8.45 m2, an aisle of 4.20 m2 and the technical room of 7.3 m2. The Technical faces on the external walkway, so as to have a window, 0.50 x 0.50 meters, to ventilate it in case of occurrence, as the generation systems, both heating/cooling and ventilation are located inside it.
As it can be seen, the distribution space is reduced to the minimum, in order to increase as much as possible the spaces for the other rooms and create linear and simple interior spaces.
The night-zone, instead, is arranged along the north side of the building and is composed of three bedrooms: the side bedrooms designed to accommodate one or two people, depending on the family, occupy an area of 17.40 m2; the central room, which is the largest, is the parents bedroom, and has an area of 23 m2, with a wardrobe room inside.
The two side bedrooms have two entrances from the outside through a glass door, one on the short sides, 1 m wide and 2.70 m high, and one from the north side, 0.8 m wide and 2.70 m high. The windows instead, also symmetrically

arranged, are much smaller due to their exposure, 1.50 meters high and 0.50 m wide. The parents bedroom instead has a glass door of 0.80 x 2.70 m and two symmetrical windows of 0.50 x 1.50 m.
With this internal distribution it was possible to divide the spaces according to their functions, with the bedrooms, separated from the “representation”
areas and the services arranged in the central block.
Doors and windows are positioned in axis to facilitate cross ventilation, in the case in that those on the same axis are simultaneously opened, as in the day-zone with windows and doors between kitchen and study; or along the three axes that are formed between day-zone and night-zone, i.e. kitchen-bedroom 1, living room-parents bedroom, study-bedroom 2.
The main shading system of the building are the verandas composed by a steel structure with recycled beams and bamboo lamellae: on the east and west sides it protrudes 1.40 meters and is inclined at 15 °; on the south side it has the same inclination, and photovoltaic and solar thermal panels are installed above it, and protrudes 2.8 meters. In the latter case the fixed shading system serves to create an additional external space sheltered from bad weather and sunrays: in summer it help to repair from the strong solar

radiation, not allowing it to enter the building, while in winter the sunrays are lower and penetrate for the whole length of the day-zone. In addition to the verandas, every window and door-window, except for those on the north side, has sliding screens in steel and bamboo that offer additional protection from sunlight and an additional tool for privacy and security.
Lastly, outside the building, in the east side, there is a staircase, made of steel and wood, which allows access to the green roof, 0.90 meters wide (tread 0.29 m, elevation 0.175 m), reaching a height of 3.50 meters, i.e. the roof decking.
