Hi Polly
Not Quite, at least not usually. I have found courts that were behind the house of the same number, but that is not usual and has usually been because it was the first court in the street. Court 31, mentioned above, is accessed between 147 & 149. It is best to assume that there is no relationship between the court number and the number of the house. It is made a bit more complicated because sometimes courts go up the street 1,2,3,4...., and at other times go odd number 1,3,5.. up one side and even the other, the numbering system for the courts sometimes being different to that used for the houses. (though this is probably because houses were renumbered in street, but court numbers were not).
