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.

5/10GreatSchools RatingParent Rating AverageThe quality of classes and teachers at this school is exceptional. The classes are thoughtfully designed, engaging, and promote active learning. The teachers are not only knowledgeable in their subjects but also go the extra mile to ensure every student comprehends the material. Their dedication, approachability, and willingness to support students outside of class truly enhance the learning experience. It's evident that the school takes great pride in maintaining a high standard of education through its outstanding classes and dedicated teaching staff.Principal Review2y ago - Silverthorne Elementary School

5/10GreatSchools RatingParent Rating AverageDual language school with a diverse student population served by a staff that is positive, nurturing, and committed to student success. Very involved home/school community. Test scores published by Zillow do not reflect the strengths of this school given the large percentage of students for whom English is not their first language.Other Review2y ago - Summit Middle School

4/10GreatSchools RatingParent Rating AverageThis school is one of the worst you can go to. DO NOT SEND YOUR CHILDREN HERE. This school smells super highly of drugs. After being reported many times the school has taken no action but a sideshow they showed to the students about how vaping isn't good. It had no mention of drugs in that sideshow anywhere. This school is also extremely reverse racist. They only punish the white kids. Im not trying to call out anything or even be racist myself but it's not fair to the white kids. For example if a Hispanic kid were to drop the n word, which i have heard a countless amount of times. They wouldn't get in trouble, but if a white kid says shoot outta frustration they get in trouble or even suspend. Its stupid. I've been going to this school for 3 years and i have racked up a list that's 5 pages long with over 100 reasons why this school sucks, and kids should not be sent here. This school has had a ton of fights break out. I witnessed one where even though everyone saw including the teachers and even rhe principal, they all just watched these kids beat each other up. The person who stopped it was a teacher who was inside and saw the fight out his window so he rushed out to stop it. This is udderly idiotic. One of the school counselors is also terrible. One time he pulled me in to ask for my opinion then disregarded me, and proceeded to tell me my opinion did not matter. This school doesn't care about learning disabilities, mental health, or overall education. They only want your money. PLEASE DO NOT SEND YOUR CHILD HERE for their own good.Student Review7mo ago
