I think its way bigger than 24 square.
I dont have one, but using a photo of it and comparing it to building dimensions on the Korber website, the front office is effectively 180% (9 windows wide vs. 5) the width of General power and light, which is listed at 13" wide. That makes the front office about 24" without the factory on the back. The factory is at least 3 JLC manufacturings wide (30") and the length of those is also almost 2 feet. I'd say your space is way short.
Think a little outside of the kit box and you should be able to build a factory that suits your needs. A 12-16" square factory (can't forget the parking lot and loading docks in your 2' square) is will within kitbashable limits using Ameritowne, Korber, DPM or even Downtown Deco bits and a little ingenuity.
