Deloitte has renewed its lease at the 12-story office tower at 100 South 4th Street in downtown St. Louis, keeping the accounting and consulting firm's 22,040 square feet of space in the building just as owner Stanton Road Capital wrapped up a major amenity upgrade across the property.
Stanton Road Capital, known as SRC, announced completion of the new amenity center, called The Outpost, alongside Deloitte's lease renewal, according to Connect CRE. The timing lines up with SRC's stated strategy for the building, known locally as the Deloitte Building: a comprehensive capital campaign meant to physically upgrade the property and address near-term lease rollover, per Stanton Road Capital's own property description. That source also notes the tower was built in 1987 and sits in the heart of St. Louis' central business district, with efficient 22,000-square-foot floor plates.
Worth noting: earlier announcements from Sansone Group had described The Outpost as scheduled for completion by the end of 2025, while Connect CRE's report on Deloitte's renewal frames the amenity center as newly completed. The dossier does not resolve the discrepancy, so both versions are presented here rather than one being treated as settled fact.
What's Inside the New Amenity Center
The Outpost itself is built around an open-concept lounge available to every tenant in the building, a 100-person conference facility, a fully modernized fitness center, and grab-and-go food and beverage options, per the same Connect CRE report. SRC has framed the amenity package as part of a broader repositioning of the 260,000-square-foot property, rather than a standalone renovation.
Deloitte's renewal follows a string of leasing wins at the tower. Law firm Baker Sterchi Cowden & Rice signed on for the entire ninth floor, totaling 22,800 square feet, in a deal announced in April 2025 by Sansone Group. That firm was relocating from 100 North Broadway, according to REBusinessOnline, which reported that Brandon Wappelhorst, Nick Fiquette and Tom Bajardi of Sansone Group represented SRC in the transaction while Rick Messey and Rollie Fors of CBRE represented the tenant.
A Building Trying to Outrun Rollover
That ninth-floor deal was part of a larger leasing push at the property. In the six months preceding its April 2025 announcement, the Deloitte Building had recorded 72,800 square feet of leasing activity, according to Sansone Group. Tom Bajardi, Brandon Wappelhorst and Nick Fiquette of Sansone Group serve as the exclusive leasing brokers for the tower.
SRC's capital campaign to physically upgrade the asset and address near-term lease rollover, as described on its own portfolio page, appears aimed squarely at keeping tenants like Deloitte in place rather than losing them to newer stock. Andy Gooliak, John Salsberry and Aly Brooks of Colliers represented Deloitte in the renewal transaction.
Downtown's Broader Office Reinvestment Push
The Deloitte Building isn't the only downtown St. Louis office property getting a facelift. An $81 million renovation has been planned for the Edison Brothers Building downtown, while MAP Property Holdings has been nearing completion of the first phase of an $11.6 million renovation at U.S. Bank Plaza. Those figures come from lower-confidence search-snippet sourcing, but they point to a pattern of owners pouring capital into aging downtown office stock to compete for tenants.
Elsewhere in the St. Louis office market, at least one law firm has reportedly been negotiating to retain its downtown space amid elevated vacancy, even as it renewed a separate suburban lease, according to a St. Louis Business Journal search snippet — though the specifics of that situation remain thin in available reporting. Broader market data from Cushman & Wakefield shows St. Louis' industrial vacancy rate climbed to 5.1% by the end of the second quarter of 2026, up 150 basis points year over year, while retail vacancy rose to 6.1%, a 140 basis-point increase. Multifamily vacancy, by contrast, eased to 9.9%, down 90 basis points from a year earlier.
For now, the Deloitte renewal and the finished Outpost amenity space stand as SRC's clearest evidence that its reinvestment strategy at 100 South 4th Street is drawing results, even as questions remain about exactly when the amenity work wrapped and how the rest of the building's leasing will play out.
