We are not sure what you want. Can you draw what you want.
1) facing starwell straight on, from the quad
2) left side of stair top, facing currier
3) similar to 3, slightly different angle to show entirety of wall that intersects currier
4) looking at fitch, showing entirety of wall that intersects it
5) looking down the stairs at fitch
areas to either side of the stair top should be treated like gardens.
------------------------REVISION 2:
the brick walls that go to the fitch on one side, and currier on the other, should be in the same plane, and have a pillar-like object adjacent to the top sidewalk landing. see photo 1.
--------------------REVISION 3:
thank you for correcting the wall at the stairwell base, but it seems to have revealed another issue- the wall intersects currier hall at the same distance back from the west face as it does fitch house. i don't know if that's an issue with the stair placement or with the placements of fitch/currier.
