I believe I used the word “perch” here several times when I should have said “scaffolding.”  What can I say?  I’m not very good with words.  [Update — a pal of mine just told me the preferred term is actually “cradle.”  But she’s British, and they’ve got some funky linguistic differences with us — with their “flats” and their “chips” and their “bangers” and their consistently correct grammar and all that.]

The guys on the right side of the building (near the very top) are about 20 stories up.
