Hi I will try and help
can you just tell me a bit more about the make up of the property
where are the other properties in relation to yours? are they next door like terraced properties, or is is more of a leasehold Flat arrangement?
and who owns the freehold?
so is the roof, or roof space part of the freehold?
in that case you would need the consent of the other freeholders, and (depending on where the property is) you woudl probably have to offer them something for it.
You would then just change the terms of your lease to incorporate the roof space, or the entire roof if you wished to take responsibility for the outside as well, and then re-register at the land registry.
you would need to get a professionally drawn plan to incorporate the new dimensions within the altered lease
I hope this helps. Do ask any follow up questions you feel you need to.
I need to pop off for a bit shortly. if I have answered your questions then please click to leave me positive feedback. The question wont close and so if you think of additional questions later on you can always as them at that point.
So to sum up
First step is to approach neighbours that I would like to access the loft space as a more habitable space. Putting in a window and boarding up rafters.
If they agree to a window (at my cost) and allowing me to use space that would be best option.
Second option is that they say if you make loft into a habitable space you need to take responsibility of the whole loft
Third option is that they may say you have to take responsibility of whole loft and roof, and at this point I would have to purchase it off them.
Would an estate agent have to come to price the roof, or could I just offer then £5000k each for it?
Then as you said depending on 3 scenarios above.
Scenario 1 – no change
Scenario 2 – purchase loft space off them – terms of lease would need to change and land registry re-registered (imagine all solicitors costs neighbours costs including plus land registry fees will all apply to me). I would then need to get plans re-drawn with new dimensions.
Scenario 3 – purchase loft and roof off them - – terms of lease would need to change and land registry re-registered (imagine all solicitors costs neighbours costs including plus land registry fees will all apply to me). I would then need to get plans re-drawn with new dimensions.
New plans to show new dimensions – is this an architect or land registry?
