A rare opportunity in the heart of Boulder, 3055 23rd Street offers a nearly 1/3 acre, flat lot, ready for new construction. Situated on a desirable, established street, this exceptional property provides a sprawling canvas with water and sewer connections already in place. The expansive, level lot opens the door to a wide range of possibilities for creating a truly special home. The generous size of the property is particularly well suited for a spacious single-level design, making it an excellent option for those seeking the convenience of main-level living. If you've been searching for the ideal setting to build a home with room to spread out both indoors and out, this lot offers outstanding flexibility. Bring your architect and your vision, or explore the potential of the site through the sample renderings by Fanas Architecture included in the photos. These concepts highlight just two possibilities: an expansive one-level retreat with an oversized garage, or a multi-story home featuring two primary suites, a rooftop deck, and nearly 3,500 square feet of living space. Beyond the property itself, enjoy the very best of the Boulder lifestyle. World-class hiking and biking trails are moments away, with Ideal Market Shopping Center just a short walk and the dining, culture, and energy of Pearl Street only a five-minute drive. This is a rare opportunity to build a custom home on a generously sized lot in one of Boulder's most sought-after locations.
