Key Operation Inc. Architects | Flat Double Decker
Renovation of a 20-year-old condominium unit, single bedroom and kitchen, 30m2, aimed for creation of a common living and dining area together with individual space for privacy for two residents: a single parent and child. The existing room partitions were removed to create one large space, and a lime-green bunk bed for the residents was placed towards the back as vertical sleeping quarters.
Between the walls and this “double-decker “bed box,” as it were, a full perimeter of corridors maintains 60 cm of clearance. The bed box has privacy doors that are normally closed or stowed. When opened, the doors close off the corridors and block the view from the living area. Moreover, the ladder for ascending to the upper bunk and the hidden lower bunk become accessible. When the large doors to the closets located at the back are opened, they provide quick privacy between parent and child. These types of privacy doors are installed at four locations, and can also create a number of different, small spaces.
For instance, the doors can close off the sleeping quarters from the living and kitchen areas, partition a study nook to the right back of the desk, or close the front and back of the parent’s bedroom for a quiet reading space by the window. Even when the doors close the corridors, the bed box is not flush to the ceiling, which remains entirely open. This arrangement allows each of the spaces to avoid a constricted feeling. To secure height for the bunk bed on this ordinary, higher condominium floor, flooring beneath the bed was applied directly to the concrete with sound-absorbing material, and the ceiling was left with structural concrete exposed.
Opening the doors to the bunk beds causes the neighboring space to close off. This change in ambience can unfold over the day: family time, study time for the child, private time before sleep, etc. The sense of distance traveled around the bed box provides more spaciousness than the actual physical dimensions.Location: Shibuya-ku, Tokyo Architect: Key Operation Inc.
