The gigantic Peachtree Dunwoody Pavilion office park redevelopment plan is getting even bigger, topping 1.1 million square feet of more housing, hotel rooms, parking decks and offices. The community can get a close-up look at the next community meeting, slated for July 12, 6 p.m., at Sandy Springs City Hall.

The latest site plan for the Peachtree Dunwoody Pavilion redevelopment, from a city filing.

The redevelopment of the 19-acre office park, at Peachtree-Dunwoody Road and Lake Hearn Drive in Sandy Springs’ Pill Hill medical area, was proposed in March. Almost every part of the plan is bigger in the official city paperwork developer the Simpson Organization recently filed. Multifamily housing units are up to 335 from 250, and an office tower went from 11 stories to 18.

The project requires rezoning for the mixed use and will seek use permits for heights that include the 275-foot office tower, two parking garages around 100 feet tall, and the 64-foot-tall residential building. The existing parking lot is about 1,175 spaces; the new parking total would be nearly 3,000, according to the filing. The project requires review by the Atlanta Regional Commission as a “Development of Regional Impact.”

The plan is still less dense than allowed under current zoning, which would be about 1.5 million square feet, according to the project filing. Three existing buildings in the office park, totaling 340,000 square feet, will remain.

Here are some of the changes to the plan since its first draft was presented in March:
