The Setting
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 sq ft lot, 521 Hawthorn Avenue sits near the center of it all: a short walk to Ideal Market, a quick ride to Pearl Street, and close enough to the Goat Trail and North Boulder Park that errands and trail runs can coexist in the same morning.
The Architecture & Elevated Systems
Inside, freshly refinished ebony-stained floors span the main level, grounded by radiant heat and framed by oversized windows that draw light deep into each space. Crown molding and millwork are consistent and thoughtfully executed throughout. The home is equipped with dual-zone air conditioning, built-in humidification, and high-efficiency mechanical systems designed to operate quietly and reliably in the background of daily life.
The Gathering Spaces
The front living room centers on a gas fireplace flanked by shuttered windows, a warm and inviting setting for evenings in. The adjacent dining room comfortably accommodates long dinners and full tables without feeling oversized. Toward the back of the home, the family room flows into the kitchen, where an oversized island, premium appliances, and a sunny dining nook create the natural hub of daily life. A dedicated home office sits mid-flight on the staircase, separated enough for focus while remaining connected to the rhythm of the house. A mudroom with direct access to the heated garage completes a main level that feels intuitive and well organized.
The Primary Suite
The primary suite occupies its own corner of the upper level, with a curved bay of windows that fills the sitting area with natural light throughout the day. The well-appointed bathroom features a freestanding soaking tub, a floor-to-ceiling tiled walk-in shower, marble countertops, and polished nickel fixtures.
Spaces That Adapt
Three additional bedrooms on the upper level are generous in size and filled with natural light. One bedroom is en-suite, while two others are served by a full hallway bathroom and a conveniently located laundry room. The finished lower level introduces a different scale, with a spacious great room ideal for media, fitness, or secondary living. 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.
Outdoor Living
The lot is a defining feature. Level, expansive, and beautifully landscaped, it provides breathing room rarely found in this location. The expansive front porch sets the tone, while a backyard patio extends from French doors off the family room. Complemented by a brand-new hot tub, the yard is private, sheltered, and ready for year-round use. Both attached and detached garages provide space for vehicles, gear, and storage without encroaching on the yard itself.
The Life It Offers
521 Hawthorn Avenue is a home with meaningful scale and genuine warmth, set on an oversized lot in one of Boulder's most sought-after neighborhoods. The layout is thoughtfully designed for how people actually live, with spaces to host comfortably, gather intimately, and work from home without compromise. It's the kind of address, and the kind of community, that people tend to stay in for a long time.
