The drawing is thinking, the same mark used over and over, up and down, hurdling scales quickly, the pulled edge of the sheet mimics the line. 

There is one idea — on the right, closer up — a study after or rehearsal for the three-quarter view bleached out from the left which comes quarried, convex from uneven ground to a concave entablature, to bow an attic, all fluted. A corner trifle of cartoon squinches to drip the interior perhaps?

It is the repeat that makes the cut of the space, a layered negative – the fillet of course helps to bend to circle and dome, milled to scallop shadow until surface transcends armature.

A print of the drawing sliced along these lines attempts a pop-up Poelzig. The cuts, with iteration, expand in scale and reduce in number as tabs for a roll of space (with  an arch to get in maybe) from a page much the same size as the original and a paperclip for tension and rhyme.
