I could not find a bookcase, etc. larger than the dimensions of the gap to put there, and it drove me crazy.

(i.e will closed properties show up as actively for sale, with accurate dimensions (more or less)?

It didnt work for me but maybe I did it wrong.Most ALL flat roofs need to be reconstructed to pitched roofs.What is the dimensions?

This will be adding a new dimension to our skill sets.

Assuming that those are about 10"-12" tiles I'd probably find or build a bookshelf/cabinet, about 3' high, with the base, if not the entire thing, the exact dimensions of the gap.

Electric water heaters usually aren't extremely expensive.Save yourself some grief though and find one with the same dimensions as the one you're replacing (height and width).

To further clarify the "every job is unique" comment, every job is unique to different contractors because every contractor has their own preferred brand of equipment.A Goodman furnace will have different supply plenum dimensions that what would be seen with a Trane, Arcoaire, or Lennox.

Picture the floor plan being laid in two-dimensions on paper as I describe this.

Congratulations on a great deal.You should speak with the building department about minimum bedroom dimensions.
