Work will begin shortly on a large mixed-use development on Peachtree-Dunwoody Road in Sandy Springs across from the North Springs MARTA Station, according to Chip Collins, an attorney for developer Trammell Crow Residential.

The Sandy Springs City Council on April 5 approved a conservation easement agreement that was the only hurdle remaining for the project. The agreement, part of the settlement of a lawsuit over a previous developer’s larger plan, requires preservation of a two-acre greenspace to serve as a buffer for neighbors.

The project on the 10-acre site will include a six-story, 236-unit apartment building and a five-story office building. Collins said the developer has a land disturbance permit and will begin work this month. Construction is expected to last 18 to 24 months.
