The 11-story hotel is built on a narrow site with only 6 meters frontage width, located in Taito, Tokyo.

The pillar used in an 11-story building are usually 800mm square with economic span. However, by subtracting the size of the columns from the frontage of 6 meters while securing the minimum effective evacuation route width of 1.2 m on the legislation, the leftover space that can be used for the hotel rooms will be extremely limited.

Therefore, we set the pillar span to about 4m pitch of the general economic span and finely arrange the pillars, so that the size of the pillar become 250 mm square, which usually used in building under 3 stories. By adopting this ultrafine pillar design aligned with guest rooms, the room width is kept to the maximum for the narrow frontage.

In business hotels where economy is regarded as important, it is difficult to introduce a decorative or directive design in terms of cost and space size. Although the space between each pillar are extremely narrow while using 250 mm square pillar depth, we are aiming for effective interior design.

To utilize the dead space of the depth of the pillar, we use soft lighting to create a floating lightwood along the corridor. The guest room utilizes the depth of the pocket, and by applying wall storage that can store TV and amenity, it makes it a clean and functional design that the column will be concealed.

The rooftop restaurant added wooden panels to the pillars and beams, while keeping the lightness of the top light, enhance the warmth of the tree. By adding our design to the solution of the building structure against a narrow area, we aim to be a compact and comfortable hotel, unlike an ordinary business hotel.
