Basement Walls And Ceiling
At the end of this phase there will be a fairly waterproof
basement. There will be holes in the ceiling (ie main level
floor) where the stairs will eventually go up and for the elevator
(and view hole),
but tarp covered wooden covers can be put over the holes. The
basement windows will have been fitted. If wanted you could
even live in the basement (unofficially).
The portico bases (safe room and south porch) are included in the basement phase.
There will be clean ICF Lego tops three feet above floor level with 30 inches of corrosion-proof rebar sticking up above that. There will be 3.5" keyway notches in the top of the concrete of the wall formed using polyethylene wrapped 2x4s.
