Houzz is the new way to design your home.
2 sided fireplaces
I like this one and that way you could do the dry wall insets on both sides.
I really like this one. Would have to be a small version but it could include the rock to match the porch outside, plus have the dry wall cut outs
I like this look for the downstairs fireplace
this is kinda cool offset like this but would want shelves for pictures
