hatch

Hi Currently have a loft hatch that is just a lid that you push up and move out of the way which you have to do off some step ladders. I'm wanting to change this to a pull down hatch with ladders if possible to make access easier. The house is 1930's so not sure if my existing loft size is going...

So i had to cut a few hatches in my tongue and groove chipboard flooring, for my new kitchen for plumbers and electricians to get access. However when avoiding the nails there are some that dont rest on the joist. Is it ok to "daughter" the joist to support the new hatches? TIA

hi Stupid error on my behalf. It's a .7m x.7m hole. Can I retrofit by grinding out some mortar, slipping in some flat metal ties and remortaring? It will be hard walked and skimmed so prettiness is not an issue here. Thanks
