Joe, you need to record with a higher sound level, thanks.

A 30 square 7 ft box out Gable End roof with furnace and chimney pressurized return interior tongue and groove gusset, could incorporate a two foot parapet and landing on both sides 4 ft in from both rake ends to a greenhouse installment with Leuvers. The vortec turbine gutter roof design gives indoor plumbing it's final destination of perpetual hydro electronic automation through the sprinkler system double 5/8 water closet, incorporated dumb waiter, and the outside spicket at 90 psi. Supplying a rain barrel catch of highly rich Bentonite soil run off to a delta water shed area mineralization. Of coarse I think a 15 gauge Carlyle rubber roof would have to carpet the attic, and up the walls, where the water could pitch to the sump differential...based on those physics, in my opinion.

Sound science I'll take 3 of em eh

Joe: Can you form a basement footing on grade with 18" form boards and line the inside with a water barrier to stop capillary wicking ?
