Deductions & credits

I have similar situation. Looking for some clarification to your reply. 

1. Where do I add the separate structure as an asset?

2. Also, the separate structure was paid for separately from the house mortgage. We had a personal loan for part of the expenses. How do I account for that? The loan is in our name, not in the business name. Does that matter? can I still put it as a business loss/expense?
