Hiroyuki Ito designed the apartments with an open structure, optimizing the upper and lower spaces radially thanks to the fact that their connection is made by means of a ladder, which allows the vertical communication space to be reduced to its minimum. The interior finishes leave the walls and slabs in their structural finish of exposed concrete.
Regarding the façade, the composition of the windows is organized differently for each floor, responding to both security and aesthetic factors. The arrangement of windows has been placed in different positions for each floor, responding to the evacuation requirements and maximizing the views towards the surrounding vegetation.

Description of project by Hiroyuki Ito
This project comprises a nine-unit housing complex overlooking an inner-city park. Within the margins of single floor height restrictions, a loft space was created on each floor.
Ordinarily, a loft is made by inserting an elevated area into a room with a high ceiling, as it is thought that such an integrated space is simple means by which to expand.
Conversely, in this project the upper and lower spaces can instead be considered to connect through a hole in the floor. Thus results an ambiguous situation in which the room is composed of a separate and distinct top and bottom, albeit while still constituting a continuous space. This spatial uncertainty is reflected in subtle, rather than contrasting, differences and a mirrored relationship in form generates a novel dimension of expansion and introspection.
On the façade, windows have been arranged in varying positions for each floor, satisfying evacuation requirements and maximising views out onto the surrounding greenery.
