I have inherited a flat in a old building which has an attic and I have been told that it does not meet the standards now needed to class it as a bedroom. It has it's own stair way although it does turn sharply at the top and anyone reasonable tall has to stoop slightly. It is at least 8 foot high with a 4 foot section running the full length of the room in the middle. The sides then slope with the shape of the roof ending with a two foot high wall both sides. It has always been used as a bedroom and has its own window and door. Can anyone please advise as to where I can find the necessary rules and regulation I need to bring it up to date and be used as a room as I intend rent out the property. Thanks
