Has anyone done this? We have our eye on a house with the most hideous dormer on the front roof - God knows how it got planning permission. I can see the flat roof causing problems too (it all looks quite old). I can see it being a really nice looking house if we were to take it down and turn it back into a loft as the storage would be more useful to us than an extra room. I think improving the appearance of the house might add value too as it seems cheap. Ideally I would take out the staircase to make more room on the landing. Would we need planning consent, would it just be a stupid waste of money (we might factor it into an offer)? I am guessing it could cost as much to take down as it did to build due to the amount of work needed in the roof?
