Guesstimate somewhere between 30m to 50m?

based on approx size of the site and the fact that it's almost a square

Approximately 34 meters

The blocks are also slightly offset from each other, so perceived distance might be larger especially for the units that don't directly face the opposite block.

For imagination purposes, a full size basketball court length is around 28m. Distance between T2 blocks are only slightly past that.
