Agree.I think it steps up from the Greenway to North End nicely. It's a nice transition building.
Greenway Pergola +15.0
This building +30.0
North End +40.0-60.0
There is not a lot one can do with a footprint of 1068 feet (the Urban Exchange parcel), Fork which probably has a footprint of 1400-1500 square feet, and Wedge, with a footprint similar to Fork.
And there is the matter of current building codes and rear egress for both this set of buildings and the abutting apartments. A residential unit atop Urban would be so close to the abutting apartment that one could go window to window between the two.
