Hall to continue building

This is my first mod and it is to continue building a hall. It is intended primarily for snowcats or other vehicles. I wanted to ask if someone can write in the comments below how to create maps. Perhaps he could also write this name and good changes. Then he'd have a place in the credit part. Appropo: if this hall would show up in a map, a place with as credits would be nice too.

Thanks in advance :)
