Hi

We have seen a house that we would like to purchase, however it's too small
for us and would need to be extended. I have had a quick chat with the
local planning dept and they indicate that there are no immediately obvious
reasons why a planning application to extend the property would be blocked.
However the snag is that the plot has a slightly odd shape (curved boundary)
and I am now concerned that the extension I would like to do may just cross
over the boundary in one corner - that this is the case is not absolutely

Regardless of planning permission - if you are wrong, and the owner
turns up a couple of years down the line, there is no way that you could
avoid his demands that you remove the encroaching bit.
