Are you thinking these are like kitchen and bathroom extentions, but sort of joined back to back, or side to side type of thing with next door, and the gap in the middle and the end would be the two backyards (the washing appears to be at the end facing wall. The front of the houses would therefore be a continuous row of terrace. They do look very big though for back extensions. I thought they were some sort of indyustrial premises when I first saw them...the washing threw me.....
If so we would be looking for a row of terraced houses with some sort of allotments and a patch of spare land at the back.
Looking at the roof shapes there are a lot of terraced houses in the area around Blackburn Rd with those sort of roofs...college street, Park rd, tremellen st, etc etc
Bye the way have you tried BING maps. gives a very good 3D view from above ...better than the direct overhead view from above in Google maps, but not as good as google street view. You can sort of circle around like in a helicopter.... Might be easier to view..try it
Bing Maps - Driving Directions, Traffic and Road Conditions
Then a post code or address then "birds eye view"
