One of Atlanta’s leading preservationists is lambasting a local developer’s plans to transform Midtown’s Master Mind Thinker Building into a mixed-use residential and hotel tower.

Tenth Street is planning an L-shaped project at 1450 West Peachtree St. that would rise 20 stories on two sides over the two-story, historically designated Winnwood Apartments.

Atlanta Preservation Center Executive Director David Mitchell told commercial real estate blog Urbanize Atlanta Tuesday that Tenth Street Ventures' plans would “besiege” the Winnwood, one of the last remaining buildings in Atlanta built in a Georgian Revival-style.

The response comes after Tenth Street filed plans last week to develop a high-rise project connected to the 15K SF Master Mind office building that would include 171 multifamily units, 141 hotel units, 5K SF of coworking space and 29K SF of retail, restaurant and commercial space, Bisnow first reported.

Atlanta-based Urban Landings, which formed after four managing partners of Tenth Street Ventures split in 2021, partnered with GBX and Easements Atlanta to renovate the 90-year-old Winnwood property — listed on the National Register of Historic Places last year — into a micro-apartment project with 50 affordable units, according to Urbanize.

Mitchell said Tenth Street’s “lamentable” plans fail to focus on preservation and could have benefited from more civic engagement, Urbanize reported.

“The renovations and historic preservation [of Winnwood Apartments] are happening in tandem. This project exemplifies the way you wed together our needs of today with the vision of the past by keeping something that is Atlanta,” Mitchell told Urbanize.

Tenth Street principal Brian McCarthy told Bisnow last week that his firm's $100M project with 15 stories of residential, retail and hotel space over five floors of parking, would incorporate housing for low-income Atlantans, with plans to break ground within the next 18 months.
