Create an arch forest.
This space is a support facility for children with developmental disabilities.
Children who have difficulty walking walk in wheelchairs.
Children who cannot play freely outside.
For such children, I wanted to create a refreshing space like being in the forest while staying inside.

Existing buildings have many windows that allow enough natural light to penetrate the interior space.
The outside environment passes through the window and changes the interior space according to time and season.
The arch frame is composed of a simple grit plan to gently divide the functional space.
The space created by the arch became an external space with forest-like properties.
As if exploring the forest, children walk in search of a cozy place.
Repeat the discovery and search and decide where you are.

A space where children can breathe together with the natural environment while in the inner space, feel the four seasons of Japan and develop their five senses. Aiming for such a place.
