Unique Spiral Shape House in Tokyo, Japan by Mount Fuji Architects Studio1

This Spiral Shape habitat comes from Mount Fuji Architects Studio and is located dominion Tokyo, Japan. intrinsic was built for a couple in a residential area of the city. The site is located at the top of a barrow connected with a narrow path leading to the actual building bevy. The ground smash is gradually climbing primary from confine of the site.

At the center of the polar coordinate is condensed with 32 pieces of the LVL columns, forming a large central jamb with the diameter of about 1.1 m. The interior is divided into four territories by this finance pillar, connections the twin arrangement found in the run-of-the-mill Japanese houses in apologize for shaped plan divided attentiveness four territories – although the hole does not occur in fixed 90 degree for the model is based on the polar coordinate. In addition, the money point is defined at the eccentric mark in the planar to differentiate the section from the circumference, while the rotation attribute of the column-beams is maintained in innate practice.

The site has particular sense of oppression and dusky feel, and the actual building lot is completely enclosed by the adjacent houses, we realized with the characteristic of the place as the depths of the urban condition without exposing to the outside, and secluded from the town.The geometry achieved through “Cartesian coordinates system” is typically applied in architecture since it has advantage in terms of the repetitive expansion in a fixed orientation.

However, this system is not suitable here as previously described. Rather, it is desirable to apply a geometric rule, which can pick up the subtle, close relationship and the balance between the site and its edge conditions. Thus, we decided to utilize the “polar coordinates system” as the geometry defining this architecture, which describes the location of an element by the distance and the angle from the center of the site.

In detail, the arch-shaped “column-beam” frame structure made by LVL/Laminated Veneer Lumber in 51 mm thickness is rotated in the regular angle of 11.25 degree (360 degree/32 frames) to form this architecture. Each frame gets 55 mm higher than the previous one, therefore there is the height difference of 1.7 m in frame as they go around 360 degree.

This system forms the fluent Hyperbolic Paraboloidal curve surface providing the entrance to the roof terrace, while it also functions as the high side light that brings in the only open sky toward the east and the greenery of the neighboring house as a framed picture.
