So - replies in no particular order!
My impression from the agent is that the owners (executors) just want a quick sale and haven't bothered to apply for planning for replacement, but plot is priced as if there is planning!
House before it burnt down was not in keeping with village and was a 60's brick house with upvc windows of "no architectural merit" We would not be happy to just replace it
We did contact the planners but they would not commit to anything constructive - unless pre-application in writing with fee, but not time for that.
If the house had not had a house on it, it would have been a possible candidate for infill,. Village quite small, i know of 1 other plot 500m away that was an infill application 5 years ago, turned down, but overturned and successful on appeal
thanks for advice
