I cannot confirm that, my GE is 38cm. However, I'm also interessted in the heights of the modulars, because I'm planning to build a shelve, which should be able to stack five buildings vertically. And I think, that the official height of 26.5cm of the PS is wrong. I do not have it, but when comparing it with other modulars on images, it looks more like 29cm. So I would also really appreciate it, when someone can post the exact heights (including details on the roof) of all modulars.
