Are you asking how to use that corner area, or how to use that tiny cupboard space where the cutout in the drywall is? Either way, a sketch with dimensions would be helpful. Hard to advise without knowing the size of the areas, and how that corner relates to the entire room.

We need more context. Ex: what will the room space be used for? What are the dimensions of the space, as well as the opening/door? What is behind the opening/door?

Put shelves up there and let the cats play.

Hi, thanks all for taking time to reply. The door goes into the eaves (storage ). The room is the master bedroom (so children don’t need to share). Just looking for ideas on how to use the corner space with it being such a weird shape. The dimensions are approx 4 foot high by 3 foot width

How about a dressing screen? You could but whatever you want to hide behind there as well (totes, chair for semi clean clothes, etc)

More pictures and we need something for scale

Is this an 8 foot ceiling or very tall ??? I know the picture makes sense to you but it doesn't to us.

i’d tuck a modern desk and chair under there

I think the angles are interesting and do not find the other choices better but we need a ton of info to help starting with what this space is now being used for . An actual floor plan to scale can also be huge help

There's really no way most drywall guys are going get a sharp internal triangular corner in tape and mud in the shape on the right. Most tools won't even fit in the point.

Since it's a loft, would look better to drywall the flat wall behind the support beams, and leave the beams visible. Paint the beams to blend in, or highlight them. It's not too late to do that.

I still think could be interesting and BTW any drywall person worth their cost can do this nicely . I think it just adds a bit of interest to the space but we need to see the whole space please .Post the pics here in a comment DO NOT start another post

You must not see a lot of typical drywall jobs Patricia. Even the flat work and 90-90-degree inside corners are usually nothing to write home about.

How often would you be going into that storage area? Can't tell with out pics from further back and different angles, but could this be closed off with a door and made into a closet to hang clothes ( something that is easy to remove so you can access that door)?

Otherwise , you could put a dresser there - something that is easy enough to move.

I agree with everyone about that odd drywall triangle on the right.

Op gone?

Hi all and thanks for your comments. I will take some more pictures later today. In answer to the other questions we’ll need to get into the eaves storage space quite regularly… I asked about leaving the beans visible and this isnt allowed due to fire regs- Unless the wood is specially treated. But thanks again for all your thoughtful replies

I actually had a fabulous drywall guy when I had my reno business before I retired and he took a challenge as a learning curve. I live in Canada where smooth drywall finish is the norm so no crappy drywall job hidden with texture . I still need to see the whole space . I do agree the one on the right is odd but I do not think any FIX will make it better

Since you need to access that area frequently, can make a bigger opening? And move it over so you could stand a piece of furniture against the side wall?

Unless the special treatment is very difficult, I'd still consider leaving the beams exposed.

What part of the OP's statement above:

"I asked about leaving the beans visible and this isnt allowed due to fire regs- Unless the wood is specially treated"

don't you get?

I'm suggesting that the OP investigate what the special wood treatment is. And if it isn't too hard, do that instead of drywall because then it will meet the fire regulations.
