Efforts to develop a SoBro site with a 24-story mixed-use tower are moving forward, as the company behind the planned project has released some updated images and schematics.

Washington, D.C.-based Douglas Development Corp. seeks to undertake the project at 522 Fourth Ave. S. and on a collective 0.78 acres. The high-rise will offer six retail spaces and 525 apartments (150 studios, 314 one-bedroom units and 61 two-bedroom residences). A fitness center, swimming pool, dog-washing room and 277-space structured garage are planned.
