The Roost: A Passive House Retreat in Maine's Wooded Landscape

The Roost, a 232-square-meter residence designed by OPAL, sits on a wooded hillside overlooking a Maine lake with filtered mountain views. Built as a year-round retreat for a large family, the house maximizes a limited building footprint within a conservation easement. A two-story porch at one end provides a protected entry, screened porch, and sleeping porch. All bedrooms are upstairs, while the ground floor features expansive glazing for connection to the forest. Interior warmth comes from native ash paneling and cabinetry, plus two efficient wood stoves. The exterior palette includes a stone base, unfinished eastern cedar at ground level, and dark-stained cedar above to blend with evergreens and reduce visibility from the lake. Landscaping uses local stone to echo nearby ledge outcrops. The building follows Passive House principles: high insulation, energy recovery ventilation, airtight sealing, and triple-glazed windows. The compact form and simple roofline mitigate energy impact from large glazed areas. Porches add 46 square meters and feature exposed white oak frames, referencing traditional Maine seasonal cabins.
