1500 Market Seed Building Addition

About the Project

1500 Market is a 16,000 square-foot, three-story iconic office building with a fourth level mezzanine at the busy corner of 15th and Market. It connects to the historic Rocky Mountain Seed building, built in 1880. The existing tenant on the second floor of the Seed Building, GoSpotCheck, grew substantially over the past few years, and is the built-to-suit tenant occupying the entire new building. The interior open-office design intentionally exposes the building’s inner workings: steel supports, wood beams and decking, and polished concrete floors. The distinctive exterior is a modern structure of steel and glass that lets in ample sunlight and reveals to passersby what’s typically hidden in neighboring masonry buildings. This project is the winner of two awards, the 2017 Mayor’s Design Award and the 2018 Downtown Denver Awards.
