A few of the houses in Caterham Road have been converted into "flats". Look at the next property to 42 where there are two doors to one semi, one presumably opening onto a staircase giving access to the first floor rooms.
Yes they have but the point is SB and JM interchange "house" and "flat" throughout their WS's. SB makes it clear the shared property was a house. If you look at the postcode finder you will see some numbers have an a A and B, I assume denoting the properties that have been separated into two? Unfortunately 42 isn't one of them.

The property JM moved into during early Sept was a flat. Liz Rimmington also lived in a flat. EP obviously got their wires crossed!
