ATX Tower is getting a fresh set of office digs, and this batch is designed for tenants who want to skip the construction headaches and just get to work. The owners of the downtown tower are rolling out move-in-ready spec suites in the building’s office stack, a play aimed squarely at smaller and more flexible tenants who have been slow to commit in Austin’s softer leasing market.
Landlord readies plug-and-play offices
The spec suite push was first reported by the Austin Business Journal, which detailed plans to carve out fully built spaces on the tower’s office floors for smaller tenants and professional services firms. Reporter Cody Baird framed the move as part of a broader pattern downtown, where landlords are trying to make office space simpler and faster to occupy in order to get leases signed.
What’s available now
The office portion of ATX Tower runs to roughly 123,000 square feet across floors 14–19, with large column-free floor plates and terraces, according to leasing materials from Endeavor Real Estate Group. The tower also features a 20,000-square-foot flex workspace on the 13th floor and tenant amenities that include a sky lounge and private terraces, listed on 325West6th.com. The mixed-use high-rise was developed with Tishman Speyer and Ryan Companies and topped out in 2024, per design firm Handel Architects.
Why landlords are offering spec suites
Spec suites are showing up across downtown for a reason. Office vacancy has remained stubbornly high, with the Downtown Austin Alliance’s Vitality Index pegging average downtown office vacancy at about 20.9% in the fourth quarter of 2025. In that kind of environment, developers and brokers say ready-to-go space helps cut down on friction by removing lengthy tenant improvement timelines and big upfront buildout costs, a strategy the Austin Business Journal previously highlighted at projects such as Eastbound in 2024.
What this could mean for tenants
For smaller firms and professional services outfits, the spec suites at ATX Tower could function like a fast pass to a downtown address. Instead of months of design and construction, tenants get a turnkey layout paired with tower amenities. Industry research indicates that amenities and polished, move-in-ready design can help coax employees back to the office, a trend landlords hope will also steady foot traffic for the ground-floor retailers and restaurants, according to CBRE.
Leasing and next steps
Floor plans, marketing materials and broker contacts are available through the ATX Tower listing at Endeavor Real Estate Group and on the building’s site at 325West6th.com, which outline current availability on the office floors. Prospective tenants can review layouts and request tours directly through those pages.
