Description
Set on a rare quarter-acre in the heart of Boulder, 2940 18th Street is a newly constructed architectural residence by Annette and Dennis Martin, designed to live as beautifully outdoors as it does within. Clean lines, open rafter eaves, and a standing seam metal roof frame a series of curated living spaces, where a south-facing great room and terrace capture natural light and views, seamlessly extending to a private pool courtyard anchored by a year-round saltwater pool, limestone hardscaping, and an outdoor kitchen. Inside, the home unfolds with an open-concept layout, vaulted ceilings, and a refined material palette-European white oak floors, custom oak cabinetry, and bespoke steel detailing throughout. The kitchen is a true centerpiece, appointed with Gaggenau and Sub-Zero appliances and striking quartzite surfaces, while thoughtfully integrated millwork enhances every space from the dining room to the primary suite and mudroom. Custom lighting from renowned international designers, artisan tile, and curated fixtures elevate the interiors with a quiet, modern luxury. Designed for both performance and longevity, the home features a HERS score of 8, a 9.24kW solar array, Tesla Powerwall battery storage, and advanced home automation. Completed in 2026, this is a rare opportunity to own a meticulously crafted, design-forward home that balances sustainability, sophistication, and seamless indoor-outdoor living.

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
