We recently purchased a lovely 16thC house which has an old original 5ft wide staircase into the loft. It is obvious from the bricked up windows in both the gable ends and the visual remains of plastered walls that at some point in time the attic area was used as living accommodation. We naively thought that it would be possible to reinstate these areas into bedrooms but our architect has advised us that this is highly unlikely to be allowed and at best we might get approval and consent for possible office use but not as actual living space. Has anyone had a similar situation or any advice on the problem? What would have happened if previous owners had still been using the rooms and we only wanted to maybe add en-suites, would we have been told that we could no longer use the attic in this way? Really confused and very, very disappointed that what seems to us an obvious plan now looks a no-go area.
