House in Goshikiyama / Tomohiro Hata Architect and staff
Text description of the architects. This house is on a very small plot of land by the railroad tracks. In order to plan a house for five family members in this place, it seemed necessary not to close oneself physically in this place, but to establish a connection to the city, also to fold every living space three-dimensionally on a small area and in a compact way.
I wonder whether we can derive a unique mathematical form from such a background of this house and develop it as a small but universal spatial framework like a new grid?
Initially, we focused on the staircase, which is not only connected to the upper and lower floors, but is also an indispensable link between the steps of the retaining wall and the street. Because the footprint is so small that it seems filled when the stairs are arranged, I added several functions and meanings to the spiral staircase that swirls from the city to the sky.
This spiral is an approach that connects inside and outside, a staircase, a staircase that connects the places, a space that rationally folds the place inwards and outwards, a window that guides light and wind inwards, and a central one Pillar in the structure.
Positioning the architecture as a bridge connecting the overwhelming city and the sky creates the image of a huge house. It is the skeleton of the room itself that loosely folds the room.
