The Hollow Box House – A Forest in the City
The project is a multifunctional urban housing complex, including spaces for working, exhibition, commercial activities, and living.
The building is organized as a “hollow box” — a continuous spatial structure generated from voids. Hollow walls, hollow floor slabs, hollow staircases, and vertically connected spatial layers increase connectivity and natural light throughout the house.
The house is defined by only two solid side walls, while partitions at the front, rear, and central areas are minimized, creating an open and flexible structure adaptable to a wide range of functions.
Surrounding the building is a multi-layered vegetation system, envisioned as a “forest within the city.” The greenery is arranged through different layers of light and shadow, allowing it to naturally grow as a small ecological system, while reducing western solar radiation, improving the microclimate, and creating visual depth from the interior. Nature is not an additional decorative element, but an integral part of the architectural structure.
The Hollow Box House proposes a model of multifunctional urban housing: open, flexible, connected to nature, and adaptable to contemporary living conditions.
