Occasionally a building emerges thai seems to transcend architecture's inherent limitations. Tokyo designer Junya Ishigami's Kanagawa Institule of Technology (KAIT) Workshop is one of those buildings. Articulated with minimal means—exterior walls of thin glass and interior clusters of slender white columns—Ishigami's ethereal structure is barely a building at all. While the transparent enclosure exposes everything inside, the delicate steel columns define scattered oases of open space, each one a different functional component. Awash in soil daylight admitted by glass bands overhead as well as the building's transparent envelope, Ishigami's meandering interior landscape creates the ambience of a tree-filled forest, not a college classroom.
A stellar debut, KAIT Workshop is the 34-year-old architect's first realized building after launching his practice in 2004
following a four-year stint working for Kazuyo Sejima. More recently, l/l he authored Japan's pavilion at this year's Venice Biennale (page 77). y
Like the pavilion, the 21,410-square-foot workshop is modest in scale. u
Yet this single-story glass box is the centerpiece of the school's 32-acre q campus, whose 40-year-old buildings are currently being replaced one by one. When this ambitious makeover is complete, the workshop will be visible from KAIT's main gate, where its 5,000 budding engineers and scientists pass each day. Located in Atsugi, an exurb 20 miles west of Tokyo, KAIT, like most Japanese universities, is a commuter school. Though Ishigami's parallelogram-shaped building gently challenges the rectilinear grid of pathways uniting the campus, it fits comfortably within the existing walkways encircling its site. The building has openings on all four sides, but its main entrance, indicated by an indented doorway and thin steel canopy, is closest to the campus gate.
Open to all KAIT students, the workshop accommodates nonacademic, creative pursuits ranging from molding silver pendants to assembling solar-powered cars. Daylight floods the building during school hours, while ceiling fixtures and task lamps enable the factorylike facility to operate long after classes end for the day. The one-room building contains 14 freely arranged, open spaces. These include a check-in area, denoted by an Ishigami-designed, donut-shaped counter, as well as specialized areas for pottery, woodworking, computer graphics, metal casting, and other media. There are also four multipurpose work spaces, a small supply shop, and an officelike alcove for the facility supervisors. Ishigami eschewed organizational devices, such as structural grids, proscribed circulation paths, and even walls (the closest lavatories are next door). Instead, he used rectangular columns, furniture of brown wood or white steel, freestanding HVAC units, and potted plants to modulate the whole 16-foot-high space.
"I wanted to create a building where it isn't clear if there are any rules at all," explains Ishigami. Yet it took a lot of work to reach this objective. In response to the client's request for many small spaces instead of one big studio, the architect started with a 13-foot grid of rectilinear columns but quickly found this framework too limiting. So he made incremental modifications to the pillars' positions, dimensions, and orientations. This enabled him to focus on qualitative criteria—such as the size and distribution of open areas and their relationship to one another—and to sculpt the space as if it were clay.

A labor-intensive process that went on for three years, Ishigami's rigorous design phase required endless iterations involving 1,000 study models of various scales and drawings—both CAD-generated and, especially, hand-drawn—that enabled the fine-tuning of multiple variables at once. The completed building's 305 columns appear randomly distributed and arbitrarily shaped—290 variations of a quadrilateral—but were, in fact, very deliberately designed.
"Due to the complexity of the columns, it was important to keep the structural system as simple as possible," says structural engineer Yasutaka Konishi, a contemporary of Ishigami's who worked on
