About 8270 Se 31st Street
A rare offering in new construction: true one-story living + a full daylight lower level in Summerwell, a bespoke community of custom homes designed by McCullough Architects. Truly an architectural masterpiece of incomparable fit & finish, bathed in abundant natural light from sunrise to sunset. Soaring 10-14' ceilings + clerestory windows crown the open concept main level, where the dramatic great room w/fireplace + gracious dining flow seamlessly into a chef's kitchen w/pro Miele appliances, Poggenpohl cabinetry + walk-in pantry. An entertainment deck extends the main level outdoors, ideal for effortless hosting + everyday relaxation. The main floor primary suite + second bedroom/office deliver the single-level ease so rarely found in new homes - perfect for those right-sizing without compromise, multigenerational flexibility, or simply planning ahead. The lower level is made for guests + gathering: 2 private guest suites (both ensuite) offer comfort + autonomy for visitors, while a generous rec room, dedicated media room + versatile flex room stand ready for movie nights, a home gym, hobbies, or work-from-home days. Step out to the covered outdoor living area w/its own fireplace + savor true year-round indoor-outdoor living, rain or shine. Wonderfully integrated spaces, sophisticated finishes + a floorplan that simply works: single-level ease up top, room for everyone to spread out below. A one-of-a-kind residence designed for you to love where you live.
