160 S 36th St, Boulder, CO 80305

Welcome to The Tree Door House, a one-of-a-kind, net-zero home in Martin Acres backing directly to open space, with a private gate from your backyard onto the Bear Creek Greenway. No street behind you, just mature catalpa tree shade, green apples, a pear tree, a sturdy play structure with Flatiron views, and rare quiet. Inside, thoughtful details reward a close look: interesting angles, warm wood accents, fresh paint, and a light-filled living room with high ceilings. The office sits behind the home's namesake: a charming tree door with built-in desks and shelving. The remodeled kitchen pairs an Italian Bertazzoni induction range with Energy Star appliances, pine cabinets, a breakfast bar, a 3-stage water filter, and a tile detail that carries throughout the home. Both baths are modern and fully remodeled in Porcelanosa tile, and the primary suite adds a Bain Ultra jetted tub, a walk-in closet, and direct access to the backyard deck. A window seat in the second bedroom, a secluded third bedroom, and a private adobe courtyard straight out of Santa Fe. Over $180,000 in upgrades make this Boulder's rare turnkey net-zero home: large solar power system with two Tesla Powerwall battery backup that have kept the lights on through multi-day outages, heat pump heating and cooling, a heat pump water heater, an EV charger, smart irrigation, and a 50-year Class 4 hail-resistant roof. All-electric comfort with little to no energy bill. Steps to the Bear Creek path and Martin Park, near Creekside Elementary, and minutes to the University of Colorado. Homes like The Tree Door House don't come around twice.
