Portman Holdings is moving ahead on a plan to transform a dated Halpern-owned shopping center located on the edge of the Virginia-Highland and Morningside/Lenox Park neighborhoods into a mixed-use project.

Portman plans to fill the 11-acre site with 1,100 apartments, a large percentage of which would be affordable. The Amsterdam Walk project also calls for 150,000 square feet of commercial space. The Atlanta Business Chronicle reports that current tenants of the Halpern retail center will be given the right of first refusal on the new commercial property at a discounted rate of 35%. The purchase of the shopping center is expected to go through soon at an undisclosed price.

Portman will also purchase roughly 2 acres from the city near the Beltline to add to its assemblage. Portman says plans will be developed over the next 14 to 16 months.
