Developers have received design approvals for an apartment project planned in downtown Dallas' Harwood Street historic district.

Centurion American Development Group — which last year completed the $250 million redevelopment of the landmark Statler Hotel — is building the six-story apartment and retail building a block away at Harwood and Jackson streets.

The building will sit atop an underground parking garage that is being built and will also serve the Statler and the historic Dallas Central Library building, now occupied by The Dallas Morning News.

Developer Mehrdad Moayedi said 130 residential units are planned in the new building, which will face the planned Harwood Park.

He said it's too early to decide if the units will be for sale or for rent.

"We think we can sell them but we have to figure out a price that works for everybody," Moayedi said.

The ground floor of the building will have 5,000 to 6,000 square feet of retail space, plus a leasing office and a gym for residents. An underground garage with more than 800 parking spaces will serve the Statler and The News.

"By November or December we'll be finished with the parking structure and then we'll start building the apartments," Moayedi said.

The developer has been working for months to get final design approvals for the project, which must fit into a historic district with buildings dating to the 1800s to the 1950s.

Dallas architect 5G Studio Collaborative designed Centurion American's new building.

"We worked with the new park to make sure they liked the design and the building was not too tall," Moayedi said.
