Ogrydziak prilling Architects have designed a design house in Piedmont, California. This project involved major renovation and transformation of a 1974 cast iron and concrete brick house for two in a house for a family. Unaffectionately known in the neighborhood as “the bunker” when the new owners bought the house in 2001, the original house has turned its back on the street, and from appearances was very private. In the free plan supported an agreement fluid program that has not led to spit the original dedicated private house 7,000 square feet was built by and for a concrete magnate whose company has supplied concrete to Highway 13 nearby. As such, the manufacture of cast in place vaults existing concrete barrel was exquisite – a clear testimony to the original client and love the museum’s architect Kimbell Kahn. However, because the house was built as an arrangement of interconnecting rooms set around a central courtyard, privacy was at a premium, the only sources of light from the courtyards and rear. The challenge of the project was to help new owners understand how the house could be made habitable for a family without sacrificing the positive qualities offered by the original intent architecture.The redesign was to make a home for practice Family and upgrade finishes and feel of the house while remaining true to its original spirit of large areas of exposed materials and visual openness. The primary living areas, kitchen, bathroom and all have been reconfigured to maximize the flexibility of space – the improvement of spatial continuity and openness of the existing house while creating opportunities for private enclosures. All jobs were coded by the material to emphasize the difference between concrete, brick, moose, and travertine shell and the new decision space interventions.Modifications the hull are in wenge, travertine, blued steel, hot rolled, or Bronze anodized aluminum, while new interventions are white oak, etched glass, white marble, white plaster or sheetrock painted white. In the lounge, a glass enclosure houses a home on the axis with the pool beyond. Fully functional sliding glass doors open to perceptually expand the interior space in the yard. The new kitchen can be opened to engage fully in the life of the house or can be closed for formal occasions through the device of oversized folding doors. Three new rooms – developed as pieces developed for processing cases that are “embedded” in the existing masonry shell – were also added to the house, each requiring the windows in the walls solid from outside.
