Congratulations on your new home. It looks like there was a door to the closet at some point, but it was removed - probably because there isn’t room to open it with the bed where it is. Maybe it’s still in the house somewhere. Otherwise, you can buy a prehung door and install it or have it installed. You need to put the measurements on paper (or use digital space planning) so you know what clearances you have, etc. The open shelving could be converted into cabinetry with drawers on the bottom half or 2/3 and cabinet doors on the top if you want the storage. Otherwise, you could have it drywalled over. Do you need the exterior door? It’s hard to advise without measurements, but that may be a better wall for your bed and that could be converted to a window instead. Think about your budget also, because this work adds up. However, having a good plan for what you want to see in the end means you can do projects as you can afford them.

Do you need adoor the to outside ? I think changing that to a window would be agood first step.It would be very helpful to post a to scale floor plan showing all the spaces and doorways and what is in the wall ,outside this space , where the built in shelves are ? Make sure to show the closet . Use graph paper to make it easier , post here in a comment in jpeg format . DO NOT start another post.

If it were mine,

I would remove all the moulding around the openings and the little crown moulding at the ceiling. a sheetrock taping professional can retape all the edges for a clean wall finish.

The only actual door you need is the entry door.

the closet interior can be painted a contrasting, complimentary color, build proper shelving units and built ins to suit your needs, some with cabinet doors to conseal, hangin out of visual sightline.

I would also highlight just the backwall of the shallow shelf I see and display only treasured items. (remove all the shelves and start over, maybe a mirror or large art piece and then a shelf or two. Mount the TV on the patio door wall. Hang ceiling to floor linen or sheer panels to draw eye upward. ... I would not change it to a window, the egress is great.

keep the room light with simple light, but textured bedding and a large area rug under the bed.

Tall lamps in front of slim mirrors will help bounce natural light around the room.

Don't know how atttractive the outdoor space is but I'd be reluctant to give up a direct access from the bedroom to it if it's nice. I once had an apartment in Italy with direct bedroom access to a terrace with a beautiful view, and it was fantastic to be able to walk out first thing in the morning, and I would have enjoyed it even without the view.

Before you spend money to close up the door I'd check out how to make the door a slider or open the other way. And I would begin to conceive of at least part of that outdoor space as an extension of your bedroom space.

I would also not be afraid to use delightful drapes instead of closet doors. You could have a wonderful garden bedroom, or even a monochroamatic romantic dream-space, incorporating well-chosen drapes.

Wanted to add this photo. I would eliminate the built-in low chest, but would consider a bed frame set up like this on the wall facing the door to the garden. I would tweak the design of the structure (probably opt for a padded headboard, elminate the open shelf, create night-stand height cubbies, etc). I also would change the room to use narrow double French doors opening out to the patio, and put a dresser to the right of the patio door.

I think we really need more info and a plan.

Congrats on the new house! Agree that changing the door to windows makes that wall more useable - Id be tempted to put in a higher set of windows so i could float a bed beneath (i think this could fit ? but hard to know without room measurements) -

if the wall with the door is indeed the best wall for the bed, you could hang floor to ceiling drapes along the wall and put the bed in front - i think this leaves the room without a window? so not ideal, but maybe a short term solution

(i would drywall up those shelves as well)
