The Setting
Newlands has the tree canopies and quiet streets that feel like they've always been there. Boulder’s best trails are close enough for morning hikes. Meet friends for a walk around North Boulder Park or for coffee at Beleza, then be home in minutes. Foothill Elementary is at the end of the block. Pearl Street is close enough to feel like part of your routine, but the rhythm here stays residential and unhurried. This recently built net-zero home sits on a 10,761-square-foot lot, the kind of generous streetscape people move to Boulder hoping to find.
The Architecture & Finishes
The exterior blends modern lines with natural white limestone and custom steel. Inside, the craftsmanship tells a story: the great room's fireplace mantle was milled from a cottonwood that stood on this property, while shelving and the mudroom bench came from honey locust trees that grew here. Wide-plank white oak floors, exposed structural steel beams, floating vanities, Arhaus lighting, sleek cabinetry. The details are quietly luxurious. A net-zero solar installation means your energy footprint shrinks while your quality of life expands.
The Heart of the Home
The main level is where life gathers. Kitchen, dining, and living spaces flow without interruption. The kitchen centers on a ten-foot quartz waterfall island with storage on both sides and space for stools. Mornings start here with coffee. Informal dining happens at the island or adjacent to the kitchen, while the formal dining room at the front of the home handles holiday dinners and occasions that call for a more gracious setting. A walk-in pantry and butler's pantry with wine storage keep counters clear. A linear gas fireplace anchors the living room. The mudroom entry is generous enough for ski gear, backpacks, and grocery bags, with a pocket door that closes it off when company arrives.
The Desirable Floor Plan
Upstairs, you’ll find four bedrooms. The primary suite spans one end with a custom limewash fireplace, two walk-in closets, and a spa bathroom with soaking tub, glass shower, and double vanities. Two secondary bedrooms open onto separate balconies and share a bathroom. A fourth bedroom is en-suite, while the laundry room completes the upper level. On the main floor, a bedroom with en-suite bath works as a guest room, home office, or nursery. Downstairs, a spacious recreation room becomes whatever you need: playroom, media lounge, home gym. A wet bar and cork-floored wine room anchor one end. Another bedroom suite offers privacy for guests or extended family.
The Indoor-Outdoor Flow
Sliding glass doors connect the main living spaces to a generous backyard. The patio extends the kitchen and dining area outside with room for a grill, dining table, lounge chairs, firepit. Summer evenings and weekend mornings happen here. The lot is large enough that the yard feels like a true extension of the home, not an afterthought.
The Life It Offers
503 Hawthorn Avenue is turnkey: move in, unpack, start living. No compromises on finishes, no deferred maintenance, no wondering if the mechanicals will hold up. The layout gives you room to grow and adjust as life shifts. The location puts you in one of Boulder's most established neighborhoods, where the access to nature is near your doorstep, the walk to school is safe, and the sense of community is real.
