I crack of natural terrain carves through the 16-story glass facade of One River North, (ORN), a new mixed-use development near the center of Denver, Colorado’s River North Art District (RiNo). More than just an apartment building, One River North is a vertical landscape for its residents to wander as if hiking in the mountains. "Imagine living in a building yet feeling as though you're immersed in a natural landscape—like living within a canyon itself," says MAD Principal Architect, Ma Yansong. As residents traverse the building's canyon trail from the 6th to the 9th floor, they become immersed in curated environments inspired by Colorado’s foothill and canyon ecosystems, guided by the sounds of cascading water that is audible from the street below. With One River North, MAD seeks to reimagine urban living by integrating natural experiences into modern architecture, creating immersive living experiences that foster community and strengthen residents' connections to each other and the natural world.
