Another Loft Hatch Question:-(

Good afternoon all on a soggy bank holiday
I know this question has been asked a thousand times so please forgive me for asking it again.
I have a 1930’s detatched property which has the loft hatch in the bathroom.
As I am installinfg a new ceiling I want to move the hatch to the hallway as not to disturb any of my family who like to take marathon bath sessions for hours at a time
The loftspace is made up of joists at 320mm centres with a ceiling binder on each side.
To the centre is a single prop.
Please see photos and drawing. The blue tape indicates the new proposed hatch position and tape markers over the ceiling binder indicqate joist positions.
I intend to cut 2 x joists. My conceren is the proximity of the prop and ceiling binder to the hatch and if it will weaken the roof structure. If anybody has any daft electrical questions then please feel free to fire away
Apoligies again for the daft question. If anybody has any daft electrical questions then please feel free to fire away

I had the same problem, a tiny hatch in the bathroom.
Mine was so small, I had a problem with my shoulders.

You need the think about access, from ground level and loft level.

Can you get to the ladder with the things you want to take up or bring down in your hands, is there room in the loft to move things say 6 foot long?

Is there room for a ladder?
If its down, can you get past it
If you fit a swing up ladder is there roof clearance.

Removing part of two joists, you need to spread the load, fitting a spreader at both ends of the hatch, transferring the load to at least two or more joists on either side.

Heat and water vapour will escape into the roof, possibly leading to condensation, mould and even wood rot. You need a tight fitting hatch, preferably with a neoprene rubber seal, and insulation.
