I am looking to widen a chimney breast in an upstairs bedroom. Just want to add maybe a wooden frame and plaster board without doing damage to the original structure. If anyone would have any tips on where to start that would be great. Thanks.

^ This is a bit vague ^ Why do you want to widen the chimney breast, what are you trying to achieve in doing so?

Pictures would help but you're a newbie so I don't think you can upload yet.

Type in 'dry lining' or 'stud partition' into youtube to find instruction videos.

Reasons aside, you want to build a stud wall.

In general this is as you describe, a wooden frame fixed to the the chimney breast. This also needs to be fixed to another supporting wall/stud, the floor and ceiling.

not done this before but it seems to me that you should have to open up sections of floor and ceiling to locate the joists, and likely also the supporting wall to locate the studs and battens on that for fixing new stud onto. I wouldn't fix directly to the floorboards or ceiling, personally. Reason being in the future if you needed to lift floorboards, they'd need to be cut off in front of the stud, as you couldn't lift a full board If the stud sat directly on it. But maybe that's a job future you isn't concerned about because you have honed your DIY skills by then

The complexity will mostly come down to the orientation of the joists above and below.

If they are perpendicular to your new wall then all is well as you will have plenty of fixing points regardless of how wide you wish to go with your new wall.

If they are not then you are going to either need to make your new wall land on the existing joists or fit noggins between them at the appropriate place.

As above, it really depends on what you are trying to do, as you could just fix through the carpet into the floorboards if its a temporary thing.
