PAVILION_07
Above, a small pavilion built into a wall, which I imagine could extend quite some ways beyond where I’ve drawn it.  The roof, a tall shingled pyramid.

Below, a roof that modulates between a square base and a round oculus at the crown, again figured as a tall, shingled pyramid.

Come to think of it, what if we combined the two, a really long wall with a larger rotated square pavilion cut out of a portion of it (and I mean, big, like Krier big), topped with a tall, oculus-ed, pyramid?  Maybe tomorrow.
