    Nestled in the quiet beauty of Boulder Heights, just 15 minutes from downtown Boulder, this mountain home offers the perfect balance of privacy, design, and breathtaking views. Perched on a 5-acre lot surrounded by mature ponderosa pine trees, it combines natural serenity with thoughtful craftsmanship. Designed by renowned architect Steve Sparn, best known locally for the Dairy Center for the Arts, this home is filled with character and clever details. The three-story sunroom faces southeast and acts as a passive solar system, keeping the home warm in the winter and reducing utility costs. It’s also prepped for a hot tub, and the basement is wired for a sauna, giving you future options to create your own retreat. Inside, large windows frame sweeping views of the Front Range while flooding the rooms with natural light. Hickory floors and oak kitchen cabinets add warmth and timeless charm. The primary suite features a rare piece of Boulder history: a clawfoot tub from the iconic Boulderado Hotel. Practical updates ensure peace of mind, including Hardie Board siding with a Class A fire rating and durable ArmorShield II impact-resistant shingles. This home offers both function and flexibility. Whether you’re relaxing on the decks, soaking in the views, or enjoying the energy-efficient design, this is mountain living at its finest: close to Boulder, yet worlds away.
