Hi I hope this helps as I've just moved into one of the houses in the picture. Alpha Villa is now 2 The Broadway, on Google its the house by itself with the four others being 4 - 10 Broadway. These house used to be 90, 92, 94, 96 and 98 Kedleston Road till Kedleston Road was renumbered then moved.
Alpha Villa is on the corner of Sherwin Street and Broadway, but this would have been the corner or Sherwin Street and Kedleston Road.
In the 1891 Census William Sherwin lives at number 88 Kedleston Road he is the Master Brewer, 90 Kedleston Road (Alpha Villa) is occupied by other Sherwin's. I don't know where 88 Kedleston Road is but I think it is now where the old peoples home is, it used to be a vinegar factory / brewery in the past. He could have lived in there when it was a brewery.
