DDDA Greenlights $63M Catalyst for Downtown Office-to-Residential Transformation
The Luzzatto Company's Redevelopment project, High Fidelity Plaza is a GO.
The Denver Downtown Development Authority has approved a $63 million low-interest loan to support The Luzzatto Company’s redevelopment of 621 and 633 17th Street, a project known as High Fidelity Plaza.
Backed by a total investment of approximately $315 million, the adaptive reuse initiative will reposition nearly 1 million square feet of underutilized office space into a mixed-use environment. Plans include more than 700 residential units, with 70 designated as attainable housing at 60% of area median income, along with ground-level retail and activated public plaza areas designed to re-energize the streetscape. The approved financing is specific to the 17th Street towers, while Luzzatto’s separate Denver Energy Center project on Broadway continues through the entitlement process.
A Signal Shift for Downtown Denver Recovery
For Colorado’s A/E/C community, this approval represents more than a single project milestone. It demonstrates a viable path forward for large-scale office conversions at a time when downtown vacancy rates remain elevated. By introducing $63 million in gap financing, the DDDA is directly addressing the financial and technical hurdles tied to repositioning outdated office buildings for residential use, including mechanical retrofits, plumbing infrastructure, and evolving code requirements.
With The Beck Group leading construction and HLW International guiding design, the project will preserve the existing building exteriors while fully transforming interior layouts to support modern residential living.
Reinforcing Denver's Commitment to a Balanced Work/Life Community
This move reinforces Denver’s commitment to activating its central business district through strategic use of tax-increment financing. For developers, it sends a clear message: the city is willing to deploy meaningful tools to help convert underperforming assets into high-impact, revenue-generating environments.
It also underscores a broader shift in how urban cores are being reimagined. Projects like High Fidelity Plaza are not just filling vacancy, they are redefining how downtown functions, transitioning from a 9-to-5 office hub into a more balanced, around-the-clock community.
What’s Next Inline for Smooth Project Progression
The project now advances into final site development review, where zoning alignment, infrastructure capacity, and building code transitions will be evaluated. Upon approval, construction will move forward with plans to introduce a fully integrated residential experience, including neighborhood-serving retail, childcare, co-working environments, and curated community spaces.
For those watching closely, High Fidelity Plaza is more than a redevelopment. It is a leading indicator of how Denver’s next chapter is being built.
