2025 RDAA | Custom Period or Vernacular House | Slide by House | Estes Twombly + Titrington Architects

Light and a sense of ease infuse this modest New England house, qualities that turned the judges’ heads. Nautical views made this a beautiful place to live, and if the house had to sit in a subdivided former hayfield that had been farmed for centuries, Jim Estes, FAIA, was determined to honor that history. He preserved part of the hayfield by placing the long, low house on the edge of the lot and letting the grasses encroach. Behind the flat-roofed carport and porch, two 18-foot-wide peaked volumes “slide by” each other. Identical in section, the longer volume contains the entry/mudroom; open kitchen, dining, and living space; and office. It lightly touches the parallel three-bedroom volume at the end of a corridor, where full-height glass lets in light. 

Known for his understated distillations of New England building traditions, the architect grouped off-the-shelf windows to emphasize the house’s gabled forms. He also specified an externally fastened, 5-V crimp galvalume roof and locally grown eastern white pine siding that was milled nearby using old-style rotary blades. “It’s pretty rugged stuff, but that’s what has been used on barns and shingles around New England for years,” Jim says, “and it’s very inexpensive.” What’s more, the house achieves net zero energy without super-high-performance measures, thanks to 37 solar panels and smart but straightforward construction.
