Marcussims91 Conversion Request

Hey  
I'm pretty new to this all! I'm a mac user and tried to convert some of my favourite cc from Marcussims91 by partitioning my iMac! It was so difficult lol. I got a few things converted but when it came to doors and windows, I couldn't get a hang of it! Anyways, I was wondering if some talented person can convert my fave objects and sets for me! I would love for the doors, stairs, and windows to functional! AND NO pressure! Like don't want anyone of you feeling overwhelmed either!

Let me know if it's doable!

Here's a list of the objects/sets:
