Although as dzug says any will draftsman would normally include the address of the property today, back then it was very unlikely. If the he left my house in Blackacre to Mary, my house in Whiteacre to Ethel and my house in Redacre to Edith and he only owned one house in each place, they are described with sufficient certainty. I've seen hundreds of will which are as jack says, quite unhelpful (if not interesting all the same).
You could try trade directories for the area from 1927 backwards to see if your relative is mentioned in them in any of the places which MIGHT give an address. As a master builder, he is likely to have been listed in a trade directory somewhere. I also find the local studies section of the nearest library can be very helpful for picking up odd details like this. In Peterborough we are very lucky to have a huge index system which someone prepared donkeys years ago and is a real treasure for turning up missing details.
