This is a facility that intensively combines various functions of information dissemination and exchange associated with the Green Culture Zone, newly opened within the Showa Memorial Park.

The basic concept was for a “growing architecture”, in response to the developing activities of green culture, and for “parkitecture”: architecture integrating with landscape, in which interior and exterior are connected. Our intention was for a space as comfortable as in the shade of a tree that would provide support for park activities.

The building consists of 15 cylinders varied by size, structure and materials, supporting an undulating roof covered by green. Under a large overarching roof, the interior space is defined by a glass enclosure, and visually connected with the exterior space. Every cylinder contains a different room for a specific purpose, and is treated as an independent building. One feels like they are walking in a city where only circle buildings exist. Workshop, exhibition, café, library; the use of space between cylinders can be defined and reorganized by a series of furniture.

Floor materials and the finishes of the cylinders were chosen based on assumed uses of training, workshops and other activities appropriate to an external plaza, and in each activity zone natural materials were employed that could mediate exterior and interior. Similarly to the way the gallery spaces provide an interior that feels similar to an exterior.

During good weather, the operable elements can be opened up, using sash devices to enable an unhindered connection to the exterior.

The roof trusses are formed by radial extended T-bar from the cylinders, and are synthesized in the manner of a spider’s web. The trusses become higher at the connection with cylinder due to its moment diagram, producing a crater topography like on the moon. These craters receive a thick layer of soil to implant large trees, and the overall roof becomes green floating garden.

    The building was given for the public use in early spring 2006 as far I remember…
    Shinkenchiku or GA magazines, might be helpful…
    I would add that the project is special by its landscape, if you approach from the garden side-Showa Memorial Park, you don’t recognize borderline between ground and build body, the roof is on the same level and grass merges surface. Suddenly you arrive to the edge where you watch big grass field (the entry from Tachikawa city). Roofs works as a view point where are formed soft hills and placed benches, so people can stay in there…really active public space (!) or smoothly go to the ground level on the escalator, then you have occasion to look at the detail into roof structure and land on the entry courtyard…
    Some of these internal cones are build from mixed corals and ocean sand so in fact these forms are “breathing” by its porosity…in many aspects it is environmentally friendly building…
    Viva Tsukamoto San !!!!
