Hmmm,
I know every thing about this house of mine built in '94. Wife designed
it with a help from an architect, hired a contractor with excellent
reputation(he built our last house). I still have a set of blue prints.
Framing, wiring, plumbing, hvac duct runs all can be checked and traced.

Sooooo, what does this have to do with the OP's question?
