Lowering Bathroom Ceiling. How?

[m4rky]

I want to lower my bathroom ceiling by 200mm so we can get some downlighters installed and also to hide the mouldy artex that currently exists.

In a normal room I would attach a square wooden frame around the room screwed into the walls at the height I require.

Unfortunately our house is of an age where the roof comes into the upstairs rooms so two of the walls are sloping. Also there is a roof truss that goes from one corner into the middle of the room that needs to be taken into account.

First to combat the mould, I have a new bathroom Fan to go into the wall that is going to be fitted.
Also going to give the artex a good clean with bleach

I have bought a pile of 25x50mm and 50x50mm timber which I was hoping to again make a frame which is screwed to the non-sloping walls but I am unsure how to handle the sloping bits and the truss??

Any ideas or names of useful devices I can use?

Thanks, Mark

Any pictures available to help ?

I'll try and get some photos tonight.

I have very quickly (and badly) create a 3D image of the room.
Its 1.7x1.7m and the height ranges from 2.1m to 2.6 and i want to drop the ceiling to 2.4m. The red line on the picture shows my intended new ceiling.

Note that the actual ceiling would meet the truss further down towards the corner of the room and not completely obscure the truss as the picture suggests.

Does this help?

the sloping bits or the ceiling 'rake' is a particularly vulnerable and much overlooked cold spot in any upstairs room, where a raked ceiling is present.

this needs 100mm of celotex between rafters with a 25mm underdraw in order to prevent the dreaded cold spot.
