Please can you give me some advice if planning permission needs to be sort if i want to split a large attic room into two rooms. The stair case to the attic is already in my large terraced house. The two rooms would measure 13 feet by 10 and 9.5 feet by 9 feet. I would also have room for a landing area for access the two rooms. there is an original door to the attic and each room would have a velux windows which is in the attic each side at present. All i would do would be to place the partition walls for each room and landing area. The house was sold as two bed with possiblity to split the attic room into two bedroooms.
Just as a foot note the flooring is that of Joist that has normal floorboarding on i would say the joist are of orginal construction of the house and six inches in depth, so i see no issues with the flooring just the permission to split a room.
