the insidehouse & outsidehouse, designed by takeshi hosaka architects, is a private residence
in tokyo, japan. the two-storey wooden structure consists of two independent units which
complete the home. the house is constructed in a way which allows fluid movement from
indoor to outdoor spaces, as well as between the two structures. the smaller structure is
considered the ‘outdoorhouse’, while the ‘indoorhouse’ is the larger unit of the two.

the outsidehouse has a small study which opens up onto a roofless courtyard which can be
accessed from the insidehouse via the open walkway which runs between the two buildings.
using a built-in ladder, one can climb to the outsidehouse’s second floor which consists
of two open balconies.

though the home isn’t physically connected, large glass windows and cutouts in the courtyard wall
facing the insidehouse provide transparency within the home, allowing one to easily look
from the insidehouse to the outsidehouse.
