[tintagel11]

Would you kind people be able to help me.

I have seen a couple of similar threads on this site, and don't want to bore everyone by repeating stuff, but I am looking to increase the size of the loft hatch. the current size is 870mm x 600mm and I want to increase it to be 1190mm x 590mm.

I've taken pictures to try and answer the questions which I hope you will have in order to help that can be

All you have to do is move one of the trimmers (spanning between the ceiling joists) to your desired size
