About 3945 Promontory Ct

In the sought-after Wonderland Hills community of North Boulder, this 4,093-square-foot residence has been extensively renovated and pairs a turnkey main home with a permitted, income-producing ADU. Backing to the protected City of Boulder greenbelt, the home enjoys open-space and foothill views, remarkable privacy, and trail access. At its heart is a lovely, light-filled great room, opened up and crowned by a wood-paneled vaulted ceiling, with a wall of glass framing the open space and a gas fireplace set beneath a picture window. The remodeled kitchen is a showpiece in custom copper, and warm Brazilian cherry hardwood runs throughout the main level. The primary suite is a true retreat, its modern Euro-style bath appointed with beautiful accents, an oversized glass shower, double vanities, and a wonderful soaking tub that looks out onto nature. Enjoy the built-in infrared sauna, plus several other beautifully finished baths. The walk-out lower level is a fully remodeled, permitted ADU of roughly 1,260 square feet, with its own kitchen, bedroom, bath, living area, a separate radiant heat system, and a private French-door entrance to a garden patio. Rented in the past, it is an ideal setup for guests, extended family, or income, especially timely with the Sundance Film Festival arriving in Boulder in 2027. A detached garage includes a finished office with its own entrance and a half-bath. The upgrades run deep, including a new roof, full exterior stucco, fire-rated Brazilian hardwood decks with glass railings, a pergola over the main deck, two new driveways, and a beautifully redesigned landscape. All just minutes from Wonderland Lake, the private swim and tennis club, trails, Lucky's Market, and Foothill, Centennial, and Boulder High schools.
