Cool idea for a mod creator, ISP Mod, you can use different types of cable lines, DSL, Fiber, and coax. You need to build the infrastructure and the internet speed will make Cims more happy. Just an idea for a more advanced mod creator.

Do you mind if I ask how many tris does this model has?

Nice.

I think something like this would look good with a big microwave antenna on top.

These things have a tendency to be the tallest buildings in small town main street/downtown/center areas. I wouldn't mind it being an early game commercial building, though it would awkward if they spawned all over the place.

Yes; commercial variants of this would be great!

Would you consider changing these fine buildings to low commercial or make alternate versions? Functuality-wise it just makes more sense to me than a park -- your call of course.

Regardless I really like the work you did on these buildings. Also appreciate the historical background you give in the description -- very interesting! And thank you.
