Midtown’s North Avenue MARTA Station is getting closer to a transit-oriented transformation that could make the 1.5-acre site quite a bit taller.

JLL officials on Thursday released a request for proposals (RFP) for developers who might be interested in tackling the “signature tower project” that would include “direct multi-modal connectivity to MARTA’s rail and bus network,” according to What Now Atlanta.

This is the first time the transit agency has tapped a third-party real estate firm to help with one of its transit-oriented developments.

MARTA is also barreling ahead on a TOD project at the Edgewood-Candler Park train station, which includes the Spoke apartment complex and a new performing arts center. Other TODs are underway at the Avondale and Chamblee stations.

The Midtown project site, bordered by Ponce de Leon Avenue, West Peachtree Street, and North Avenue, is not limited by any building height restrictions, leading one to wonder how big the project could get.

The issuance of the RFP also comes at a time when developer interest in Midtown seems to be at an all-time high.

A CoStar report from earlier this year dubbed the neighborhood “one big construction zone.”

In other MARTA-related news, a tiny village of shipping containers recently debuted at the Hamilton E. Holmes transit stop.

It’s called the iVillage@MLK, and it features 14 repurposed shipping containters that house a coffee shop, florist, and ice cream shop, among other tenants.

The project is part of a TIGER grant-funded initiative to revitalize the Martin Luther King Jr. Drive corridor.
