There seems to be something wrong with the model size, which is much smaller than other building models with the same number of floors

thanks

Wow, this really fits a british theme for some reason.. Reminds me of a tower block in a city near me https://www.theconstructionindex.co.uk/assets/news_articles/2019/07/1562598991_vincent-wyles-and-william-malcom-1.jpg

To be honest, the best scale to suit the vanilla buildings is 1:1.5. It's slightly smaller than vanilla I guess?

Its quite out of the question to make growables bigger than 4x4 since that is the max the editor will allow without using mods or something. And this 1:2 scale barely fit that size limit.

Someday I will be getting to the RICO part. But I am currently busy and I haven't start looking into that yet.

You should make this into 1:1 scale and RICO, rather than a tiny growable. It looks small compared to other buildings. ;(
