Coastal Co-Housing Community > In this small co-housing development, three couples, committed to environmental stewardship and intelligent retirement housing, have realized their dream of aging gracefully and creatively together. The project is located on a 16-acre coastal site on which a standard subdivision with five separate houses was permitted by zoning. However, the zoning ordinance also made it possible to construct a zero-lot-line subdivision if 40% of the land remained open space. The tight clustering of this project ensures that 80% of the property will remain open. The main building is a unified composition of three homes and a commons, the latter complete with living and kitchen area, library, media room, workout room, art studio, roof deck with kitchen garden, shared HVAC systems, central garage, and an apartment for a future caregiver. The separate guesthouse has a living area, five bedrooms, and a basement playroom. Both buildings are sited and designed to maximize views, cross-ventilation, and opportunities for natural light and solar collectors. The design preserves individual privacy while encouraging interaction. A wood pellet boiler and solar collectors provide heat and hot water. A 25 KW solar array provides electricity; more is possible. Maximizing space for collectors was one determinant of building form. While each unit has a unique plan and character, the complex has a unified aesthetic and scale that reinterpret indigenous New England architecture.
