Situated on a rare 10,724 sq ft lot in Newlands, one of Boulder's most cherished neighborhoods, 521 Hawthorn Avenue offers a quiet, walkable setting tucked between North Boulder and downtown, steps from Ideal Market, Pearl Street, North Boulder Park, and the Goat Trail. Freshly refinished ebony-stained floors span the main level, grounded by radiant heat and framed by oversized windows, with crown molding and millwork executed consistently throughout. Dual-zone air conditioning, built-in humidification, and high-efficiency mechanical systems round out an elevated set of home systems. The front living room centers on a gas fireplace flanked by shuttered windows, while the adjacent dining room flows naturally toward the back of the home where a family room, oversized island kitchen, and sunny breakfast nook create the hub of daily life. A dedicated mid-flight home office, mudroom with heated garage access, and an intuitive main-level layout complete the picture. Upstairs, the primary suite occupies its own corner with a curved bay of windows, freestanding soaking tub, floor-to-ceiling tiled walk-in shower, marble countertops, and polished nickel fixtures. Three additional bedrooms, including one en-suite, a full hallway bathroom, and a conveniently located laundry room round out the upper level. The lower level is a full height daylight level with substantial natural light and functional living spaces, anchored by a large flexible great room and a private guest area with its own bathroom and separate exterior entrance. Outside, the expansive and beautifully landscaped lot features a front porch, backyard patio off the French doors, and a brand-new hot tub, all sheltered and private. With meaningful scale, genuine warmth, and one of Boulder's most sought-after addresses, 521 Hawthorn Avenue is the kind of home people tend to stay in for a long time.
