Good thought on the trans attic space but I put in an 800 square feet patio and retaining walls on the backside of house. No way you would have known that.

Thinking just drilling a big hole out front and under the stone front will be the best option. I can run out the existing box with that plan.

If I ever build another home, hoping I never do, I will for sure stub out electric and water out the back for a barn.
