unihikid: Yes, Hal Roach lived at 22 Berkeley Square...and while I wanted the view through the door to be of one of the houses across the street from his, it isn't. Or any of the other Square houses...though there are two that are visually unaccounted for.
Hal's house:

EDIT-- I
might have found the house seen through the doorway in "Ten Years Old"-- I think it's a backdrop photo of 650 Muirfield Road, built by Leo Bergin in 1923...no house was ever directly across from it. Bergin was a partner in the LA Soap Company, and we've seen various items about him before...although maybe not the bit of noir under the pics below.

From the LAT Sept 18, 1931 (not sure I got all the pieces of the story in sequence, but frankly I got tired of all the work. I'm sure you'll get the gist).
