It looks like a lot of house for the money. I don't know stoke in Trent but understand housing is cheaper there that a lot of places. I suspect:
No garage so on street larking by the look of it
Over developed for the area but that is a benefit to the buyer - houses usually have a top value anyone will pay in a certain area so it doesn't matter what you spend, you won't get it back
Surrounding area and how good, or bad it is?
What I would want to see if I was buying it is evidence of a good structural engineer being involved as the steelwork holding up the back of that house will need to be of a very high spec and welded/bolted well. I know as we have done similar and it is vital it is done well to avoid movement
