I'm certain everyone is forgetting that all the easements and the ventilation structure can be built ontop of, just because they are there doesnt make it an impossible task, just like 55 Hudson Yards was built on top of and absorbed the larger of the 2 vent structures. The vent structure and mta/Amtrak easements being there does not preclude the building from taking over the whole site so thered be no reason to think that the building cant grow larger in the portion seen outside of the render, that is why I added another twist to my render.
Developers like to use all the available space they can, theres no reason Peebles or anyone else would allow their tower to take up such a small footprint as the one created by the lower volume in the official render which is approximately 195' x 85' when the entire lot is 197.5' x ~265'.
If it does end up being just a small footprint then it just ends up being a small footprint but dont think it is without seeing the final design of the base just because you believe the building cant be larger at it's base/podium.
