Summaries of content, keywords and links generated by algorithms. Thank you smmry.com:
Summary 1: If the roof is a flat ROOF GARDEN, it can be built just like any FLOOR-CEILING VAULT.
Summary 2: Build the roof vault either as a cylindrical barrel vault, or like a pitched roof with a slight convex curve in each of the two sloping sides.
Summary 3: The roof must definitely contain lived-in space - that is, not just sit on top of the rooms which are all below - see SHELTERING ROOF.
Summary 4: Flat roofs, except ROOF GARDENS, are already eliminated by the psychological arguments of SHELTERING ROOFS and, of course, by structural considerations.
Summary 5: These roofs enclose habitable space more efficiently than pitched roofs; but they have the same structural drawbacks.
Summary 6: We have developed a range of roof vaults which are rather similar to a pitched roof - but with a convex curve great enough to eliminate bending, in some cases actually approaching barrel vaults..
