thanks, all.  i’m at a decision point on a workspace i am building.  i like
the idea of a view (otherwise why live where i do?), and the wall in
question faces mildly west of south.  trees shade most of the morning light
in summer, and winter light here is not so harsh (and it will be good to
have).

i have an old steel double casement window @3x3’ to install into an 8’ wall
over a 33” bench height, so it sounds best to push it to the top of the
wall and have space between.

greg, it’s just not going to be big enough in there (think michael’s) to
have four side access...

best,
bill
