Tucked behind mature trees on one of North Boulder's most private streets, 800 Kalmia Avenue sits on a half-acre lot and is a newly transformed modern retreat that blends warmth, precision, and timeless design. Thoughtfully reimagined in a 2024 total renovation, this architecturally rich property features elevated finishes, refined materials, and foothill views throughout.

Step inside to discover a welcoming entryway with custom built-ins and hidden storage, setting the tone for the meticulous craftsmanship found throughout. The heart of the home is a light-filled great room where wide-plank white oak floors and radiant heat underfoot create a sense of grounded luxury. A soaring paneled fireplace anchors the space, while skylights and full-height glass doors dissolve the boundary between indoors and out.

The chef’s kitchen is equally compelling, outfitted with a Bluestar range, Thermador refrigeration, marble-topped island, and unlacquered brass hardware. A walk-through butler’s pantry with additional prep and storage space—including an ice maker, beverage drawers, and wine storage—ensures seamless entertaining. From the kitchen, a Dutch door and sliding glass doors open to a lush, secluded backyard with foothill views. Flexible main-level spaces include a stylish powder room with black paneled walls and marble sink, and a guest bedroom with an adjoining bathroom that also connects to a flexible room that can be used as a private office, music room, or den. 
Upstairs, a spacious landing overlooks the main living area and leads to three en suite bedrooms. The vaulted primary suite captures southern light and views of the foothills and includes a spa-like bathroom with a soaking tub, steam shower, dual marble vanity, bidet toilet, and a generous walk-in closet. Two additional bedrooms feature bespoke details, including Zellige tilework, custom vanities, and built-in bunk beds in one of the rooms.

The newly constructed detached three-car garage doubles as a multifunctional extension of the home and includes a large recreation room with a kitchenette, a separate laundry and gear-washing area, and a powder room. The backyard is surrounded by mature trees and curated landscaping, offering privacy, flat lawn space, and foothill views. A stone patio just off the kitchen is plumbed for an outdoor fireplace—ideal for quiet evenings or gatherings under the stars.

Set in a quiet enclave just minutes from North Boulder’s most beloved trailheads and shopping, 800 Kalmia Avenue is a rare opportunity to enjoy refined living with privacy, versatility, and enduring design at its core.
