Details &
Description

Perched above Lake Dillon in the prestigious Summerwood Ridge community of Summit County, this extraordinary 13,765-sf mountain estate presents a remarkable opportunity. Offered as an unfinished shell, the home invites its future owner to complete the vision of a true legacy property. Designed by renowned Charles Cunniffe Architects of Aspen and constructed to the highest standards by Kendrick Olson Construction—one of Colorado’s premier builders—this home is already an architectural masterpiece in the making. Situated on a rare 2.14-acre double lot adorned with old-growth trees and striking moss-covered rock outcroppings, the property boasts panoramic views that stretch across the Tenmile Range and Buffalo Mountain.

The home is framed in white oak and centered around a great room with a large two-sided fireplace and floor-to-ceiling windows offering stunning alpine vistas. Expansive cantilevered decks and stone patios complement the surrounding landscape and create seamless indoor-outdoor living areas. The primary suite floats above the cliff’s edge and boasts 270-degree views and a spa-like bath. Current plans call for seven bedrooms, six full bathrooms, two half baths, a media room with a wet bar, a wine display, a gym with a sauna, and a private in-law suite. Additionally, plans include infrastructure for two 3-car garages, a heated driveway and integrated smart home systems.

Every element of this home reflects a commitment to quality and envisions custom fine finishes—from Deinesen wide plank flooring to natural stone slabs. The home represents the pinnacle of modern, mountain living, combining contemporary elegance with organic materials and bold architectural gestures. Only a handful of properties in Summit County offer this level of privacy, scale, and design pedigree. Charles Cunniffe Architects and Kendrick Olson Construction, longtime collaborators on some of Colorado’s most celebrated high-country estates, have once again partnered to bring this exceptional retreat to life. Located within 10 minutes of Keystone, 20 minutes of Breckenridge, Copper, and A-Basin, and just 40 minutes from Vail.

Nestled in the heart of the Rocky Mountains, Summit County, is a destination defined by its alpine beauty, world-class recreation, and quintessential mountain-town charm. Encompassing the resort communities of Breckenridge, Keystone, Copper Mountain, Dillon, Silverthorne, and Frisco, the county is known for its dramatic peaks, pristine lakes, and year-round outdoor lifestyle. With elevations ranging from 8,000 to over 14,000 ft, Summit County offers breathtaking scenery in every direction—from the shimmering waters of Lake Dillon to the snow-capped summits of the Tenmile and Gore Ranges.

Outdoor enthusiasts find endless opportunities here, with four major ski resorts located within 30 minutes of one another. In the winter, the region transforms into a paradise for skiing, snowboarding, and Nordic sports. Summer brings hiking and mountain biking along hundreds of miles of trails, sailing and paddleboarding on Lake Dillon, and golfing on award-winning mountain courses. The county’s central location along the I-70 corridor also makes it easily accessible—just about 75 miles west of Denver—while maintaining a sense of privacy and exclusivity. Beyond its recreational offerings, Summit County is home to a thriving year-round community. Festivals, concerts, and cultural events add vibrancy throughout the seasons, making Summit County as dynamic socially as it is geographically.
