What we have here is the housing equivalent of putting a quart into a pint pot. Instead of just building a straight row of terraced houses our greedy little Victorian builder has missed out every third house and squeezed in another terrace between the rows. So now there are eight houses where one would have been. This was fairly common practice in Hull and elsewhere I guess. These little off shoots were often given names like Percy Cottages in this case, there's a Minnie's Grove further along and I've seen an Annie's Grove as well, often however they're given somewhat ridiculous names such as Victoria Avenue which is next to old Percy here on Mayfield Street. I once lived in a similar place to this (Willow Grove off Alexandra Road, long ago demolished) and these houses are teeny, damp and squalid, how a family with children was expected to thrive in them I cannot imagine but many generations have and continue so to do. In fairness Mayfield Street is exceptional in that there has been no redevelopment, the neighbouring Middleton Street which was very similar to this has been modernised and these hutches demolished.
