Loft room timber size for floor

[skhudy]

Hi,

3 bed mid terrace, looking at refurbing the front bedroom upstairs and the ceiling which needs replacing.

I was thinking of putting in 8"x 3" timbers on joist hangers (15ft wall to wall width of room) every 400mm below the existing ceiling and lowering the ceiling - thinking of a few years down the line when the loft may get converted to something usable - and the other half of the upstairs could have the same done, and not loose loft height with supports going above the existing ceilings.

Are you still allowed to use timber only supports for loft conversions?
if so, are joist hangers acceptable?

I have looked at other postings, doesn't quite make it clear.

Thanks for any replies

You need BCO approval if it is to be a habital room.

You will need steels to support the floor too. Speak to your local BCO first.

What type of roof rafter arrangement do you have?.. the converstion may be a non starter cos you have some form of trusses arrangement..

Look at your neighbouring properties, if none have loft conversions then thats a pretty sure sign of it being pretty impossible to do..
