Featuring a panoramic view across the San Francisco Bay, from San Jose to the Golden Gate Bridge, Pitcher’s Prow, an architectural landscape emerges prow-like from a hillside in the Oakland, CA hills. Nestled against the existing house, a plunge pool and upper and lower seating and entertainment terraces cascade downward as a series of concrete and cedar planes. A steel pergola pinwheels its cantilevered triangular arms outward to shade the built-in grilling and upper seating area at the top of the site.
Seeking to re-establish a California meadow along the re-claimed slopes of the now-defunct Leona Stone Quarry, which once supplied crushed 140 million year old rhyolite rock for use in macadam and concrete for Bay Area projects such as I-580 highway, Oakland Airport, the Coliseum, berths of the Port of Oakland, and BART, the hillside plantings are a matrix of purple grasses and native plantings.
Designed for an owner with an appreciation for crisp angularity, the cedar decks, a white-steel clad pool volume and concrete prows anchor into the earth as durable monolithic forms, harkening back to the site’s stone quarry history. In much the same way that the owner’s pitching skills are based on a technical expertise of speed, spin rate, axis and elevation, the kit-of-parts pergola takes its position atop the mound, the panoramic view unfurling in front of it as the hill slopes away.
Taking a page from Jean Prouvé's kit of parts designs and loosely influenced by the steel frame house kits of the mid-1950s, the Pitcher’s Prow pergola shade structure is envisioned as the first iteration in a series of Deployable Structure Kits, seeking to utilize today's manufacturing capabilities of 3D modeling, waterjet CNC cutting, and bending tools, in a deployable kit of parts structure. Deployable Structures push aesthetic structural aspirations via long spans, inventive column design/layout, and emphasis on utilizing various steel thicknesses and shapes. Designed as readily deployable kits, the pergola kit components were trucked, hoisted, and bolted in place after columns were set.
