‘portico’ by aida atelier, tokyo, japan photography by tatsuya noaki

japanese practice aida atelier has completed ‘portico’ a single-family residential situated in a suburb of tokyo, japan. the site is adjacent to six different properties which are built very close to the boundary lines leaving the positioning of the project with a condition that limits the amount of street frontage onto the river.

in order to create an architectural language that expresses an undulating sense of peripheral density, the team set rules for the exterior spaces. the first was to not confine the building from its surroundings and to create an environment with diverse adjacent scopes to allow for a transition room that circulates the air, is exposed to natural light and is spatially open. the second was to avoid the creation of a cul-de-sac and have an outdoor area free from stagnation. where the interior is not residual but an active part of the house that simultaneously exists as an integral section to the neighborhood. and thirdly, to conceive the outer shell as a volume and not a plane. re-conceiving this area left a zone on the upper floor with a conceptual ‘garden’, that materializes another invisible chamber within the property.
