Step into a masterpiece of Denver’s architectural past. Built in 1890 by the legendary William Lang — best known for designing the iconic Molly Brown House — this extraordinary sandstone townhome is one of only three remaining Lang-designed rowhouses and holds the rare distinction of having been personally occupied by Lang himself. Nestled in the heart of the Uptown Historic District, the home is a living tribute to Denver’s rich architectural heritage. This stately, three-story structure features a bold stone façade, arched windows, and a distinctive silhouette that whispers of Denver’s golden age. Inside, original turn-of-the-century details abound: ornately carved mantels, richly milled moldings, a graceful spiral staircase, and decorative woodwork that exudes the warmth and artistry of a bygone era. Currently operating as a boutique office building — home to professionals including attorneys and wellness practitioners — the space offers rare versatility. With R-4 zoning and a layout well-suited for adaptive reuse, the property is ideal for conversion into luxury residential units, live/work townhomes, or a flagship office for a small firm. The generous 4,879 sq ft layout offers both charm and flexibility for the right visionary buyer. While priced to reflect its exceptional historical value and architectural rarity, this property’s significance, unique design, and location in one of Denver’s most walkable neighborhoods make this a truly premium listing.
