PROJECT ARAPAHE ROW-HOMES OVERVIEW
Located in the heart of Denver’s Curtis Park neighborhood, the Arapahoe Row Homes commercial architect project is a contemporary reinterpretation of the classic Denver brownstone. Completed by Catalyst Architecture Planning and Development in collaboration with development partners, this multi-unit, multi-story residential project introduces a thoughtfully scaled solution to modern urban living—blending timeless form, user-centered design, and compact urban density.
Situated just blocks from Denver’s vibrant RiNo Arts District, the brick-clad facades of the row homes provide a strong sense of continuity with the neighborhood’s historic context, while the interiors deliver contemporary comfort and functionality. Each unit spans three levels plus a generous rooftop deck with panoramic city and mountain views. With private garages, multi-bedroom configurations, and flexible lower-level living spaces, these homes were designed for both personal retreat and entertaining.
Design priorities included maximizing natural light within narrow building footprints, balancing privacy with openness in shared walls, and creating seamless transitions between indoor and outdoor spaces. A central spiral stair, chef-inspired kitchen layouts, and high-end interior finishes elevate the residential experience while remaining within the framework of thoughtful, efficient development.
