Oyster House sets a new standard for entry-level housing in Wellfleet, Cape Cod. Developable land in Cape Cod is at a premium since much of the open space is now protected natural landscape. By building smaller, Oyster House achieves more density with less impact on Cape Cod’s precious landscape. Oyster House uses less; less energy, less building material, less building area. Simultaneously, the house does more. Its pentagonal plan makes for easy siting in multiple orientations, maximizing privacy, permitting views, and responding to the sun’s path through the southern sky. The house is conceived of as a repeatable unit that can be deployed across multiple sites in the town of Wellfleet—as a single unit and as a community of houses.
