This house is situated in a compactly structured district where natural setting with ups and downs, multiple main roads, industrial lots peculiar to Hitachi and residential area mix within about 3 kilometers spanning in the east-west direction. Work places are in proximity to residences and a sea breeze can be felt near a mountain when climbing up little higher. Such ‘large area with real sense’ extends. On the other hand, commercial facilities scatter in residences in the neighborhood and almost half of the land use is occupied parking. In fact, largest parking lots in this area surround the house on three sides. A point of departure of the plan was to take in ‘large area with real sense’ into everyday lives through open space of the parking lots.

In order for a family of three to live on about 50 square meters small backyard, simple rectangular rooms are piled up. Living space resulted in narrow pieces in up and down was connected by staircases and voids. Large stair treads are built in the entire staircase and at the same time risers are shifted towards the back, so the whole staircase is as if open to below and is connected to the long side of a rectangle. The fan-shaped staircase is linked to the main building and adjusts privacy between the two houses, facing the utility zone of the main building. Also, it functions to regulate atmosphere by easing sunshine from the south and catching wind that blows to the east and the west. It resolves problems unique to addition on a 60 meter-long deep-shaped site. On the other side, rectangular rooms connect to the ‘large area’ through the open space of large parking lots on the north, and are ruled by the height from the ground, openings and the relation between inner rooms. Though having completely different contexts and sense of scale, the staircase gently covers the rooms like a veil and mutually and mildly permeates the outer space and stacked living space.
Wide treads connect various rooms and space up and down by curves in movement and give variety to rhymes and actions of everyday lives, from places such as a steep ladder to a sunlit loose-stepped terrace. The staircase prepares from tomorrow living scope that bulges out from three-layered square rooms by changing the quality from a staircase to louvers, fixture to rely bodies, responding to the depth of treads and different uses in rooms.
