Description
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.

10/10GreatSchools RatingParent Rating AverageTerrible experience here. Constantly made fun of and picked on by students and teachers treated me like a total idiot. Went from being respected by peers and teachers at my old school to ridiculed and laughed at by the entire class.Other Review2mo ago - Casey Middle School

5/10GreatSchools RatingParent Rating AverageCasey Middle has changed so much in just two years! When our daughter started as a 6th grader in the fall 2021, it was a mess. We almost transferred her based on the poor leadership and chaotic environment. Honoring that many of the issues were caused by COVID, it was still struggling compared with other boulder middle schools. However, the new principal, Dr. Bryant Shaw, is simply fabulous. He started in fall 2022 and his presence has completely changed the energy and culture of Casey! The teachers seem happy to be there, the students feel safe and known and he is seriously invested in the community. It's amazing what a caring, motivated principal can do in a short time. There is still work to be done to get the school back up to its pre-COVID reputation but its clearly on the right track now.Parent Review2y ago - Columbine Elementary School

4/10GreatSchools RatingParent Rating AverageMy son has attended Columbine since preschool and is now in second grade. He’s part of the bilingual program and is thriving in both reading and writing in both languages. He has made many friends, and we truly enjoy being part of the school community. The teachers have been wonderful—warm, supportive, and dedicated.Parent Review6mo ago
