Basic structure looks very similar, biggest difference is the more pronounced triangulation in way the firewall sides tie into the fender and side rail, likely to increase torsional stiffness:

Indeed - and the point about "platform" is not that you use all of the pieces shown in that image either. The new meaning of "platform" is that you have something similar to prefabricated Lego assemblies that you can vary by model with just a few hard fixing points, so you're barely constrained by the structural geometry.
VW's MQB platform is a great example, this:
is based on the same "platform" as this:
For comparison, the sizes/weights of those two are (rounded):
Audi TT: 4.2m x 1.8m x 1.3m (l x w x h), wheelbase = 2.5m, 1200-1400kg
Skoda Kodiaq: 4.7m x 1.9m x 1.7m, wheelbase = 2.8m, 1400-1800kg
They are substantially different in every conceivable way, yet they share a common platform. The upcoming Audi A1 is likely to be smaller than the TT, and that is also based on MQB!
