na house sou fujimoto
HOUSE NA was designed in 2010 for a couple on their early forties,  it is located in a quiet neighbourhood of Tokyo and is around 592 square feet.
HOUSE NA is compared with a tree because the tree has many branches, all being a setting for a place, and a source of activities of diverse scales. This house proposes living quarters orchestrated by its spatio-temporal relativity with one another, akin to a tree. Associated with the concept of living within a tree, the spacious interior is comprised of 21 individual floor plates, all situated at various heights, that satisfy the clients desire to live as nomads within their own home. The steps between the plates at times will become seating and desks, at times as a device segmenting a territory, and at times each akin to leaves of the foliage filtering light down into the space.                                                                                                                                                         Stratifying floor plates in a furniture-like scale allows the structure to serve many types of functions, such as providing for circulation, seating and workings spaces. The loosely defined program and the individual floor plates create a setting for a range of activities that can take place at different scales. As a result, every horizontal plane becomes a generic surface. Without a specifically defined function, they can be used as a desk, shelf, bed, chair, etc., extolling the Japanese custom of sitting and sleeping on the floor in a manner that is so pervasive and clear that, while requiring no lengthy description, gives free reign to the imagination. Elements from furniture scales come together to collectively form scale of rooms, and further unto those of dwellings, of which renders the city.
Structure: The short-spans of the house allow the usage of this thin white steel frame .For the cold days of the winter some of the floor plates are equipped with in-floor heating and the glass panes are strategically to maximize air flow and provide source of cooling for the hot days of the summer. At the north wall, back side of the side, are located the plumbing equipment, as well as storage and lateral bracing.
Levels : The house is comprised of 21 individual floor plates of various heights. There is a range of activities which take place on the individual plates at different scales. It’s divided into three basic floors and each one of them is subdivided into different levels of the plates. The plates are not isolated, but they are connected with one each other, just how it happens on tree branches .Also the plates are linked together by a variety of stairs and ladders, including short runs of fixed and movable steps. The structure serves many types of functions like seating and workings spaces, while various activities are held at various scales. The hole house acts like one individual room but at the same time as a collection of rooms. The absence of WALLS raises a number of challenges to seamless flow from one level to another.
The populous capital of Japan develops the concept of verticality. Local codes do not require a minimum distance between buildings, but require that buildings will not be in contact with each other. Naturally, it follows that the space between two buildings can be less than half a meter for this and reference our architect uses the limits of the site and not those of the house. With these adjacencies, this difference cannot be used to collect light, but only to ensure minimum ventilation.
Moreover, these windows provide plenty of natural light, which is diffused in the house throughout the day, not in all cases in which the kitchen and bathroom use fixtures. During overnight home reverses status and radiates outwardly like a small light source within the huge city of Tokyo.                                                             The few walls that exist are mostly glass, making some areas safe, except the security of privacy. Transparency and visual continuity is typical in this building where the facade is almost inexistent. The windows and curtains from floor to ceiling reign. The curtains in addition to partial privacy and offer protection from solar radiation.                                                                                                                                               Besides the great potential of the visual are the residents of NA HOUSE, the undeveloped distribution of sound throughout the house is another possibility of construction. Also the absence of isolated closed room offers full and inevitable communication.
However this building becomes expensive and inaccessible to the public and represent choices made predominantly from the elite. It can be a bit of a category of houses because is a unique example of options specific eccentric people. With this building tested a new beginning that is away from the term civil (freehand drawing as a living space, as dreamed by the Farnsworth).
