Hi,

Attached are images of what the room looks like and the obstacles it presents for a novice DIY'er. This attachment shows a few numbers which are elements important to this project and will help lay the foundations.
1 - would be a custom cupboard unit I need to build
2 - would be a custom cupboard unit I need to build
3 - is an existing partial stud box that is NOT load bearing (cupboards cant rely enitrely resting on it), the stairway ceiling is within this box.
4 - is a brick exterior wall
5 - is a paramount wall
This Attachment shows 2 red handles and also show which way the units will open. 1 and 2 will not open the same way.

The question I have is, what form of units do I need to build and how to fix them to the wall (4) without causing any vertical load (or the least possible) to 3.

I am thinking for strength building a stud carcass and then encasing this carcass in mdf sheet, then using something like this to hang unit 2 off the wall. I'm not sure on which kind of cupboard build I need for 1 and how to hang it, as the side will become load bearing? From some of the research I have done it seems like if you do a normal rear mount for a unit, you can inset a batten or put it behind the MDF backboard so the finish is flush to the wall (to offset for wall mount thickness).

2 will become mostly a clothes rail if I don't move ahead with shelving, but either way both units must be able to hold 50kg+ as well as there own weight, I am not great with understanding the strength of MDF sheets in a carcass and what can be hung off of them before material separates. I have more experience with studding stuff.

I am not bothered with hidden or ugly looking wall mounts, strength and rigidity is more important to me than aesthetics.

Any and all ideas are welcome.
Any questions let me know.

Bump! Anyone here who can help?

I would take the top off the stairwell box and reinforce it as a solid base. Make it the same widthand depth as a standard wardrobe and you might then get away with an Ikea wardrobe on top.

how do I go about reinforcing it? when it was exposed it looked like this , so if you looked at it top down, I placed timbers either side that went from the paramount wall to the end of the bulkhead and then to the floor, so either side turned into 2 right angles and fitted them in. What further strengthening do I need to do to make it extremely strong? I have added pics of inside the bulkhead that I put a small frame around and doors. There is a melamine sheet on top but doesn't feel too sturdy for me as the wall behind this is paramount, so nothing really to anchor to like a breeze block or stud wall.

Have I missed the point, have you already built it? I would have siliconed it to the paramount wall as it will firm it up. There should not be a lot of lateral movement in use.

hi mate, it's there but I don't think it's well supported (I wouldn't sit on the top melamine sheet), so my initial idea was to just wall hang 2 big units so that I would never have to worry about vertical load onto the stair bulkhead. I can do the silicone and maybe add some more timbers, any suggestions on what is required inside the bulkhead to make it extremely strong?
