Not sure what you are trying to do. If you want the counter as strings (why
would you want that?), you can just say
***********
bysort plot: gen bldg=string(_n)
***********
-string()- happily accepts -format- as well.
-tostring-`s -format()- option accepts _numeric_ formats, as you are moving
from numeric to string. If you want to -format- the finished results, do it
in a separate line, just as you seem to be implying.

I found this works, but it seems the format option should be in the
same line with -tostring-
******
bysort plot: gen bldg=_n
tostring bldg, gen(bldg1)
format %003s bldg1
*******
