I can't work out if my house is semi detached or terraced ! It was originally an end terrace of 4. It was then converted from 4 to 2 houses, so semi-detached. However at some point the other house has had their neighbour extend their house right up and actually attach to their wall! Not all the way up , but like the whole ground floor. Goodness knows how they got permission, it must have been done years ago. The houses are originally Victorian. So it leaves me wondering whether my house is actually semi detached or is it terraced as my neighbour is attached to another row of houses?! I have seen our house described as both and it doesn't bother me except for house insurance you are asked and now I'm worried I've put the wrong option.
