Gaining headroom on staircase

[ashrobbo]

Hi All,

1930's 4 bed and been meaning to investigate how I can gain headroom on the staircase. At lowest point headroom is about 1.65m which means i have to duck everytime I go up and down stairs.

I know regs are at least 2 metres at all points so i'm keen to achieve this.

Is moving a floor joist possible? The lowest point is the floor joist for the box room above the stairs. I'm happy to lose a bit of room in here and build up a bed/storage to at least make it usable (currently not used but will be an ideal cot room!).

Removing floor joist from above the stairs i could cut out more of the ceiling and get the headroom required.

Alternatively a steeper staircase but not a great fan of this idea if avoided.

Any experts?

This is possible/doable but you need to know which way the joists are going and if the trimmer joist running parallel to the stairs rests on the wall or is trimmed into the end of the other joist
Basically if you don`t know get someone in who does
DO NOT start chopping out willy nilly

Joists don't go parallel unfortunately, ill rip up a couple of floor boards and have a proper check though.

Am I right in thinking a trimmer joist are 2 smaller joists screwed to the rest to maintain strength?

Definitely wouldn't give this a go myself. I'm not sure whether to look to a builder or a career enter though.

I like to have a good idea of works involved.
