I agree Graham, but it is impossible to get people to concur on anything in a terrace. Inevitably at least one house will want nothing done, and others will expect their houses painted gratis.
Photo looks 1920-ish. FWIW, chauffeurs usually wore jodhpurs with boots, not plus fours. Also, were the guy in the photo a chauffeur, is it not likely that for a photo he would wear his full suit? Methinks it is more casual, probably a sporting photograph. The ‘fours’ refer to inches of overlap, which allowed the water to drip outside the Wellington boot, and were made popular by the Prince of W from his shooting days. Anybody who has walked through a field of wet kale will know....
Census - not sure that it would be quite as easy to locate the family by house number – the 1911 &1901 are best checked by using the family name, as number sequences could have changed. There are several Census locations for Circular Road, South as it runs through several DED areas.
