621 & 633 17th Street

Two towers in the heart of downtown Denver are about to be completely transformed.

The buildings at 621 and 633 17th Street were once worth a combined $120 million. Last month, they sold for just $3.2 million.

The buyer, California-based Luzzatto Company, has big plans to convert the vacant office buildings into 700-750 units, with a majority dedicated as affordable housing.But this isn’t just housing.

Plans call for a daycare, restaurant, co-working suites, gym, market, theater, and parking garage - bringing new life to a part of downtown hit hard by office vacancies.

Construction could begin late 2025 or next year, pending design and permitting.

The project aligns with city goals to repurpose underused office buildings and chip away at Denver’s estimated shortage of over 55,000 affordable units.

If completed, it would be one of the largest adaptive reuse efforts in Denver history, and a major step toward activating the city’s core.
