Hello BP members! 

I'm looking to convert a garage into a living space with a loft and was just wondering if any other BP member has had this done before. 

The current garage is about 400-450sq feet in size and we don't use it to store any of our cars at the moment. We were thinking it would look something like this image below:

Has anyone had a project like this done before? What was the process like? How much should I expect to budget out for a project like this? 

Thanks in advance!

Andres
