Concrete walls in the ground level protects the building from the dominant northwest winter wind. That being said, this straightforward box-shaped structure house is reinforced with polycarbonate panels on all sides including its funnel-shaped roof. On one side, the translucent facades and roof are to extend cultivation season in colder months by capturing sun light for the plants and keep its warmth; for hotter months, sliding panels in the facades and roof open to facilitate air movement, creating a natural ventilation. On the other side, the sloped shape of the roof eases rain water collection that is used to irrigate the plants via pipe system. The rather simplistic shape of the building comes from traditional Japanese language of the “house/roof as a structure”. The polycarbonate roof extending seamlessly as wall panels can be seen as a modern adaptation of their traditional structural composition. The abundance of wood in the building is an attempt to recreate an symbolic larch forest amid, from which a treehouse would be in its heart. This tree house serves as a semi-enclosed private space from which occupants could enjoy the tea ceremony, a cultural ritual in Japan. 9.250 10.100 2100 2100 2100 2100 2100 2100 2100 2100 450 450 1020 1020 2400 2200 2200 2200 850 CIRCULATION SPACE HARVEST / GROWING SPACE PRIVATE TEA SPACE PUBLIC COOKING SPACE OLIVIER DUCHARME JENNIFER JIANG ARCH 303 - U2 INSPIRATION .

Nest We Grow with the 3 previous winners of the same design-built competition, all sit on a fairly flat topographic area, nested in Memu Meadows' local farms and food cultivation. Built with different professionals, including the usual structural engineers and contractors and the unusual composting toilet manufacturer, this project incorporates Californian approach on heavy timber construction to Japanese traditional expertise on minimalist wood connections (joints). The main structure of the building is composed of a 3 x 3 grid of 9 imposing larch glulam timber columns from locally sourced larch wood by Japan-based Takahashi Construction Company. The structural beams are then seamlessly connected to module the different horizontal spacing arrangements, and thus forming, in itself, a larch communal forest using a post-and-beam timber construction method. The building is organized with its largest open area for food preparation on the ground level; with its elevated semi-enclosed platform accessible through a staircase on the second level for tea ceremonies and spiritual gatherings; and with its catwalks corridors of comestible garden on the third and fourth levels accessible through ladders.

DESCRIPTION
On the south-east end of Hokkaido, the largest northernmost island of Japan, stands a porous communal platform for its local people’s enjoyment and collective identity reinforcement. Nest We Grow was brought to realization around the same concept of community—under the melting pot of harmonious collaborations. In response to the 4th Annual LIXIL International University Architectural Competition, the winning proposal was designed in partnership with Kengo Kuma & Associates by a team of UC Berkeley College of Environmental Design (CED) students. The competition calls for innovative architectural students centering on sustainable development and housing technology; resulting in the creation of a “Productive Garden” – A Space for Enjoying Hokkaido with All Five Senses. Working closely with local resident needs and concerns, the architects were able to produce a holistic environment for the community to gather, prepare and enjoy food in a shared atmosphere accessible all year long. In other words, the building supports all stages of food production—ranging as early as growing and harvesting to the enjoyment of cooking and dining—and provides a resourceful cycle with its composting and storing abilities. These key concepts were conceptually designed, smoothly executed, and programmatically translated into the physical building.
