About This Home
As of March 2026An extraordinary opportunity awaits in Boulder's historic Mapleton Hill. In one of the city's most sought-after locations and just a few blocks from Pearl Street's world-class shopping, dining, and cultural energy, the location simply can't be beat. The home itself reflects timeless 1970's character with a classic courtyard entry and architectural details that exude mid-century charm. While the interiors are largely original, the bones are strong and the possibilities endless to create your own vision of this mid-century masterpiece. Imagine designing a modern sanctuary with the convenience of a main-level primary suite or single-level living-an option rarely found in this area. Practical features include a two-car garage (a true rarity downtown) and a private, fenced backyard perfect for gardening, entertaining, or simply enjoying Boulder's sunny days. Beyond the property lines, Mapleton Hill's sense of community is unmatched, from friendly neighbors to beloved traditions like Porchfest, where music and mingling spill across front porches each fall. This home is a blank canvas in Boulder's most storied neighborhood-an incredible chance to bring your vision to life while securing an address that will always be in demand. LIVE BOLDER, LOVE BOULDER!
