I was reading the story "Quality" by John Galsworthy. There was a phrase in it: "two little shops let into one". I am unsure about what it means.
I knew him from the days of my extreme youth because he made my father's boots; inhabiting with his elder brother two little shops let into one, in a small by-street--now no more, but then most fashionably placed in the West End.

Does it mean that the shop consisted of two "shops" and there was one entrance into the shop?
