A private guest area with its own bathroom and separate exterior entrance provides added privacy for long-term visitors, extended stays, or flexible living arrangements.

The lot is a defining feature. Level, expansive, and beautifully landscaped, it provides breathing room rarely found in this location.
Complemented by a brand-new hot tub, the yard is private, sheltered, and ready for year-round use.
Newlands is one of Boulder's most cherished neighborhoods, a quiet, walkable pocket tucked between North Boulder and downtown where tree-lined streets give way to front porches and longtime neighbors.
Positioned on a rare 10,724 sqft lot, 521 Hawthorn Ave sits in the center of it all: a short walk to Ideal Market, a quick ride to Pearl St, and close enough to the Goat Trail & North Boulder Park that errands & trail runs can coexist in the same morning.

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.
