Terraced houses such as these, with gardens too small to accomodate Anderson shelters would still have been awaiting the alternative Morrisons when, inconsiderately, as the Blitz intensified, the bombs began to fall. The only protection was to be found in the cupboard under the stairs, the staircase being reckoned the strongest part of the house. Although Lord HawHaw threatened Brighton on a least one occasion it was probably never a prime target, more the recipient of left-over bombs from enemy aircraft returning from London; or bombs jettisoned at the first sight of land by over-eager pilots anxious to get home to tea, or whatever the German equivalent was in those days.
I have spent some time trying to decide if the modern photo is of exactly the same spot. Different cameras yield different perspectives which can be misleading, and there has been much rebuilding, thankfully in sympathetic styles. I think it is clinched by what appears to be identical chimney stacks near the centre of both pictures: and the house numbering; the second house from the corner being no. 48 and the digit "8" being also discernible in the 1940 photo.
