Description

Jones Lang LaSalle, Inc. ("JLL"), as exclusive advisor, is pleased to present The Vault located at 821 17th Street (the "Property" or "Building") — a fully repositioned, 107,630 SF office and retail landmark in the heart of downtown Denver's financial district on iconic 17th Street. Ownership has invested over $22.4M into a comprehensive renovation, delivering a new lobby, restored 1st and 2nd floors, full exterior façade restoration, and modernized base-building systems. In addition, eight of nine floors are fully renovated and move-in ready, including furnished spec suites on floors 6-9 — giving an investor the opportunity to drive immediate occupancy without the cost, risk, or timeline of executing that capital program. The Vault is offered fully unencumbered by existing leases, providing an investor with the flexibility to pursue office, adaptive reuse, or a residential or hospitality conversion. A grand, 23-foot two-story atrium anchors the ground floor as a signature centerpiece regardless of ultimate use. The Building also offers a rare full-building opportunity for a company seeking a signature Denver headquarters — allowing an owner-user to occupy immediately and or grow into the Building over time rather than fund a multi-year buildout. Built in 1907 as one of the first reinforced-concrete buildings west of the Mississippi and designated a Denver Landmark in 1977, The Vault pairs irreplaceable historic character with a fully reset, institutional-quality basis.
