Plans are moving ahead for the rehab of Metro transit's former headquarters on Laclede's Landing.

An $8.5 million rehab of the building at 701 North First Street will make way for the expansion plans of Abstrakt Marketing Group, located next door at Raeder Place. The firm has said it plans to grow from about 200 employees to around 300.

Advantes Development Group, led by Brian and Mike Minges, has tweaked plans a bit from when the project was first announced earlier this year. Now, the number of apartments planned for the upper floors of the building has doubled, to 52.

"This is huge for the Landing," said Dave Sweeney, an attorney representing the developers.
