1001-17th Street was originally built for Mountain Bell in 1974 and had always been occupied by the phone company. Qwest Communications sold the building to Miller Global Properties at the end of 2006, and the 659,074 square foot property underwent over one year of major demolition and reconstruction to reposition it from single tenant usage to multi-tenant usage. The new design by Barber Architects gave 1001 a facelift that transformed it into a Class “AA” project, greatly improving the appearance of the block between Curtis and Arapahoe on 17th Street in the heart of downtown Denver.

This renovation included 22,000 square feet of newly constructed glass retail space at the gateway to Lower Downtown (LoDo) adjacent to Skyline Park. 1001 has a prominent 17th Street entrance leading to a newly constructed grand atrium comprised of exquisite granite, marble, and glass. This Concourse includes a commissioned glass sculpture and mosaic piece by the artist, Reiner John, fabricated in Germany and titled “Floating Mount Evans Sky.”

In 2013, 1001-17th Street was acquired by FSP 1001 17th Street LLC (FSP). In 2020, FSP hired Alan Colussy Architecture, LLC to design enhanced amenities in the building. Construction was completed in Q1 of 2023. The refreshed lobby elevated the current public spaces by incorporating a contemporary active design featuring individual quiet spaces and collaboration areas. The lobby and amenity floors contain multiple gathering and social zones. The Street Level amenities include a new fitness center with showers and lockers; yoga room; cardio and strength training equipment; a new expansive tenant lounge with large plasma display panels for streaming events, presentations and exhibitions; a Koi pond, and a new food and beverage facility.

The office tower is a 22-story building constructed of a concrete and steel core with steel and concrete floor pans built out from the core and wrapped with a glass and steel curtain wall system. It is a fully sprinklered building with smoke and heat detection.

1001 contains four levels of underground parking at a ratio of 1.0 parking spaces per 1,000 square feet of leased space. It offers exceptional access via Curtis, Arapahoe, 17th, and 18th Streets.

The redevelopment and renovations of 1001-17th Street had a positive impact on 17th Street and the Central Business District adding to the image, energy, and vitality of downtown Denver.
