Banking Tower to Luxury Living

Republic National Bank's downtown tower was built in 1954 — a mid-century monument to Dallas banking. By the mid-2000s it was underperforming office space in a market that didn't need more. ANDRES converted it to luxury residential apartments for Gables Residential, preserving the building's mid-century character while completely reimagining the interior program. Three industry awards followed.

Preservation Meets Program Change

Converting a 1950s office building to residential means rethinking everything from floor plates to mechanical risers to window configurations — all while preserving the exterior character and lobby details that give the building its identity. The challenge isn't just construction. It's knowing what to keep.

Complexity highlights

Mid-Century Preservation Standards

The Republic National Bank Building's architectural significance required careful documentation and preservation of key character-defining features. ANDRES worked within strict preservation guidelines while delivering a modern residential product that met current code and market expectations.

Complete Interior Reimagination

Office floor plates designed for open-plan banking operations had to be reconfigured for residential unit layouts — new demising walls, new plumbing risers, new electrical distribution, all threaded through a structure that was never designed for residential use.

Gables Republic Tower was one of ANDRES's early adaptive reuse landmarks — the project that proved the team could deliver award-winning preservation work. Several team members from this project went on to lead The National, The Cabana, and Mosaic. That continuity built ANDRES's adaptive reuse reputation one project at a time.
