The upper design on the sheet renders the top view of the domical vault
as a single continuous surface, with the courses of masonry depicted as simplified rings, while the lower design offers the correlated elevation of the domical vault
, but introduces the idea of the tripartite gored vault with its separating ribs; the squat windows on the cornice level are very lightly drawn on the paper, almost like pentimenti.
Rather like Viollet-le-Duc, whose designs for iron tension-strutted masonry domes share an unexpected similarity with the domical vaults
in the Lisbon Ismaili Centre and the New Delhi Parliamentary Library (as pointed out by Peter Davey in AR October 2002), Rewal's passage a l'acte sometimes lacks a certain lightness of touch.
Thus, creating a central yard at the middle of the building and constructing a water pond and garden in it increases the humidity in the biological environment, and also mud and brick walls, which are built with a relatively high thickness so that they can endure the heavy load of arched and domical vaults
, decrease the temperature variations during day and night as a heat capacitor.
