Greetings:

We are building an addition to our house in Minnesota. Our house has an approx 5 foot frost footing with a concrete crawl space.

My question...I'll need a frost footing for the addition; however I can't visualize how this new footing and foundation will butt up against the existing footing and foundation . On my existing foundation I have a 2x6 sill and 10 inch flloor joists with flooring. I would like the new addition floor to be level with the existing floor; however, I don't want a crawl space in the new addition. Does anyone have a cross section detail?...thanks in advance...j
