In Boulder, Colorado, a $15M contemporary mansion aims to set new local record

With a prime downtown location, the property is currently Boulder’s most expensive home for sale and is set to dethrone the city’s previous record — one set by this very house when it last sold in June 2021 for $13.2 million.

We don’t often head into the heart of the Rockies, but this week, we’re making an exception for something truly special — a striking modern retreat in Boulder, Colorado, that just hit the market with a $15 million price tag.

And if it sells anywhere near its asking price, the Boulder house will set a new local record. Again!

With a prime location at 1505 Sunset Boulevard, the property is currently the most expensive home for sale in the foothills of the Flatirons, and will likely become the highest recorded sale in Boulder once sold — dethroning a record set by this very house when it last sold in June 2021 for $13,200,000.

Past media coverage says another neighboring property (set just a few doors down at 1489 Sunset Blvd.) is the record-holder, after selling in January 2023 for a hefty $13 million. But a quick look at 1505 Sunset Boulevard’s public records show a previous sale that tops it, at $13.2 million.

Regardless, the sleek home is now back on the market and likely to set a new record in the process. Marybeth Emerson of The Agency Boulder holds the listing.

Blending modern luxury with the wild beauty of the great outdoors, the newly listed property is ideally located on a 0.44-acre lot in a prime downtown location, close to Boulder’s beloved Pearl Street. 

With the best of Boulder within walking distance, the home also enjoys unobstructed views of the Flatirons and Foothills.

With decidedly contemporary architecture, the home’s street-facing facade doesn’t really give away its size — best observed from the backyard — but lures the eye in with its clean lines, modern design, and floor-to-ceiling windows.

Designed by the visionaries at Surround Architecture, an award-winning local design firm known for fusing cutting-edge architectural design with uncompromising technical competence, and built by Harrington Stanko in 2016, the home blends timeless elegance with modern sophistication and conveniences.

Fittingly, the home has been appointed with a state-of-the-art Savant home automation system and an elevator servicing all floors.

The main living area transitions easily from the sleek, modern kitchen to the dining area and living room, with a dual-sided fireplace separating the two.

Featuring refined additions like Italian Varenna cabinetry, Miele appliances, and a Jura coffee bar, the sleek kitchen is the heart of this space.

Making the most out of its open floorplan layout, the main living area provides several spaces for lounging and entertaining guests and family, including a TV area and separate lounging that maximizes the views.

The upper-level bedrooms also have walk-out balconies, but steps were taken to ensure these don’t take away from the views and all of them have transparent railings.

While $15 million homes aren’t common for the area, the Sunset Boulevard home’s asking price is less ambitious than it sounds. Just a couple of years back, a 10,169-square-foot home on Juniper Ave was asking $19.9 million.
