maybe a huge tower?

Huge tower, radio tower, high building (with not too much details)

Apartments.

maybe a really tall and really wide tower

or maybe a modulable tower where you can stack them

i know i've already suggested twice now but maybe a tower with windows

perhaps a building with an elevator (using actual keys instead of buttons so its easier)

windows

maybe a bunker?

a triple tower with sepret rooms like a bar, bedroom, toilet, ETC

I would like to see a massive tank that looks like the german landkreuzer ratte that was never built.

Elevator

Hmm, Let's say maybe a very long building. Not very Width though. Like 3 meters?

three towers

Towers which aren't stuck to the the ground (e.g you can build a giant floating structure and put the unattached version of this build on to the ship making it float)
