Two prominent office towers in the heart of downtown Denver are slated for a major transformation. Denver-based real estate investment firm E2M Ventures (E2MV), alongside national real estate firm The Luzzatto Company, has announced the successful acquisition of 621 and 633 17th St., totaling over 973,000 square feet. The Luzzatto Company plans to redevelop the office towers into the largest multifamily project in Denver, making it one of the largest and most high-profile office-to-residential conversion projects in the country.
“The potential for 621 and 633 17th Street to become a dynamic, mixed-use development within downtown Denver is immense,” said Marc Perusse, founder of E2M Ventures, the seller of the properties. “We wanted to identify a new owner with the vision and expertise to look beyond these as one-dimensional office assets and reimagine them for the future. The Luzzatto Company stood out for their operational expertise, strong capital backing, and ability to reposition complex assets. Their plan represents an exciting transit-oriented development opportunity that will contribute to downtown Denver’s ongoing revitalization.”
The properties, which currently include a 391-stall parking facility, span a full city block and are directly served by an on-site light rail stop. The planned residential redevelopment would comprise over 700 modern units, with over 150,000 square feet of public and private amenity spaces including a daycare, gym, restaurant, market, theater, coworking suites, parking garage and more.
“The Luzzatto Company is committed to developing a transformational mixed-use multifamily project that helps support the dynamic growth of Denver’s urban core and revitalizes public-private engagement around this irreplaceable transit location,” said Asher Luzzatto, president of The Luzzatto Company.
E2MV originally acquired the buildings in November 2024 as part of a broader transaction that also included a 916-stall, 250,000-square-foot, parking garage at 1820 California St. and the adjacent 1.15-acre Lighthouse surface lot. While the Lighthouse Lot has since been sold, E2MV plans to retain ownership of the parking garage—soon to be rebranded as Park Place at 1820 California—as a long-term asset in partnership with Cress Capital.
The sale of 621 and 633 17th Street serves as a case study of E2MV’s innate ability to identify compelling investment opportunities and creatively structure complex transactions that unlock value others often overlook. The transaction was brokered by Sean Whitney, Larry Thiel, Hilary Barnett, and Mark Katz at JLL.
E2MV remains committed to the future of downtown Denver and will continue to pursue opportunities that create value for its investors and the city through strategic acquisitions, partnerships, and asset management.
