About This Property

Situated in one of Breckenridge’s most prestigious neighborhoods—Shock Hill Landing—this like-new end-unit duplex offers exceptional mountain living with convenient access to the Gondola Mid-Station. Just steps away, the Mid-Station provides effortless access to world-class skiing without the long lines in town, while historic Main Street and the Breckenridge Nordic Center trails are also within easy reach. The end-unit location offers exceptional privacy and additional surrounding green space. High-end finishes include granite countertops, designer tile, distressed wood flooring on the main level, and two striking stone fireplaces. Southwest exposure fills the home with natural light while capturing expansive views of the ski area and Tenmile Range. Interior highlights include a wet bar, built-in mudroom off the garage, boot dryer, and a custom chairlift cable handrail on the staircase. The primary suite features an Altitude Control Technology oxygen system and a steam shower in the ensuite bath.

Outdoor living is enhanced by a spacious slope-facing deck and private hot tub, ideal for après-ski relaxation, along with an attached two-car garage. The property also features a new roof installed in 2022. This is a rare opportunity to own in Shock Hill Landing—where convenient Gondola Mid-Station access, privacy, refined finishes, and Breckenridge’s iconic alpine beauty come together.
