With both Syr’Nj’s narrative and the official panel descriptions here, I set a high bar for gnomish architecture that was probably impossible to fully reach, especially without spending a lot more time focused on the buildings:

The larger panel displays Gnometown itself in all its glory, and this will be our setting for most of the rest of the story. Gnometown evidences the creativity in architecture that Syr’Nj describes and that you’d expect from such a mechanically inclined people. There is a clock tower/observatory, a pyramid, and some Le Corbusier structures. There are also pipes everywhere, because the gnomes have mastered many principles of plumbing but aren’t so good at keeping their pipes hidden yet.

Sounds like a pretty big mess, to be honest, but from what I remember of The Fountainhead, Ayn Rand would love it.
