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. Discover sophisticated design, sustainable living, and Boulder's most coveted lifestyle at 503 Hawthorn Avenue. Natural white limestone and custom steel compose the exterior, while wide-plank white oak floors, exposed structural steel beams, and bespoke details define the interior-including a fireplace mantle milled from a cottonwood that stood on this property. The main level flows seamlessly from kitchen to dining to living spaces. A ten-foot quartz waterfall island anchors the chef's kitchen, with walk-in and butler's pantries providing wine storage. Casual and formal dining spaces accommodate every occasion. A linear gas fireplace warms the living room, while a spacious mudroom handles active lifestyles. A main-floor bedroom with en-suite bath offers flexibility as guest quarters, office, or nursery. The primary suite commands one wing with custom limewash fireplace, dual walk-in closets, and spa bath featuring soaking tub, glass shower, and double vanities. Three additional bedrooms include two with private balconies sharing a bath, plus one en-suite bedroom. The lower level offers a versatile recreation room, wet bar, cork-floored wine room, and sixth bedroom suite. Sliding glass doors open to a private backyard with a generous patio, ideal for al fresco dining, fire pit gatherings, and Boulder's 300 days of sunshine. Open House Sunday, Feb 1 from 1-3pm.
