Custom Station Buildings

Hello Everyone!

Can someone of you tell me, how can I make custom Station Buildings for NoLimits 2?
Or maybe where I can find one to download?

I would like to have a custom station Building with a little plattform on the side, where I can place my Control Panel.

If you know something, please let me know! :-)
