Description

Perched atop the exclusive Ptarmigan neighborhood in Silverthorne, 421 Z Rd is a masterfully designed sanctuary blending cutting-edge sustainability with elevated mountain luxury. Situated on 1.25 acres—with the option to acquire an adjacent 1.25-acre parcel for a truly expansive estate—this bespoke 4-bedroom residence showcases some of Summit County’s most awe-inspiring views, spanning from Lake Dillon to the Gore Range. Every inch of this custom-built home has been meticulously curated to captivate the most discerning buyer. The striking copper-clad exterior makes a bold architectural statement, while inside, rich walnut cabinetry and one-of-a-kind Blue Marine Granite countertops—sourced by hand from Dallas, TX—set the tone for refined individuality. The chef’s kitchen is a showpiece of design and function, boasting premium appliances from Wolf, Dacor, and Miele, along with motorized cabinetry for seamless modern living. Even the dishwasher responds with a simple knock. Overhead, a custom interlocking wood ceiling and sculptural chandeliers elevate the aesthetic experience. Three expansive La Cantina floor-to-ceiling sliding glass walls disappear to reveal an unmatched indoor/outdoor lifestyle, flowing onto a composite deck complete with a hot tub overlooking the peaks. Ideal for buyers who value environmental consciousness without sacrificing comfort, the home features owned solar panels that slash utility costs by 80–90%, a cutting-edge SIPS roof, an advanced water treatment system, and a dedicated EV charging station. A greenhouse allows for year-round gardening and sustainability. In the luxurious primary suite, unwind in a spa-like steam shower or a soaking tub that dramatically fills from the ceiling. Located just minutes from world-class skiing and four-season recreation, this home is not only a residence—it’s a statement. 421 Z Rd offers a rare blend of eco-luxury, innovative design, and natural beauty, setting a new standard for Colorado mountain living.
