What desk space do you need . Do you need to accommodate just a laptop or a couple of screens. Cabling is also a consideration. The front window does it go to floor -shutters can be good. Do you want to be able to access the shelves easily from your desk. I would think a credenza may be best to put things away if you are not paperless but even for items like stationery and printer, etc…. Will it be just you in there or a second worker or visitor chair?

Ok so a bit more detail
It’s just my study so no kids mess in here, setting up a second study in rumpus upstairs. I need to accommodate a screen and laptop nothing else. No visitor chair or printer required. PowerPoints not an issue 2 on each walls. Here is the layout I am keen on but hesitant. Yellow is table, blue lines for floating shelves and purple is a nice comfy velvet chair

Opaque sliding doors

Your yellow, blue and purple layout leaves a blank space in the middle of the room and gives more of a spare bedroom office vibe rather than a styled space that you see as you enter the house. I’d try and accommodate a free standing desk.

i would also prefer a free standing desk with both your desk and comfy chair with a view to outside plus a wall of combined low storage cabinets (to hide away the laptop and printer) extra desk space, display shelves and maybe an art screen/tv

It depends where you want to face. Your plan has office cubicle written on it. Do you want to be squashed in corner or own the room and be able to stretch eyes with a longer dightline occasionally. A free standing desk will give you more options.

When I work from home i don’t have back to door so I can see and quickly wave to kids as they come and go, have them bring me a cuppa without them being seen on screen

I would rather be looking out the window and looking at the entrance to the room than squashed in a corner and not knowing what is going on behind me. With The measurements and shape of room, the storage would be better on the wall opposite the entrance, as per oklouise plan. And I assume you mean the window is full height floor to ceiling not length of wall.

You could put a beautiful artwork on the wall that people see when entering home. Or as @rinked as said, put opaque doors on entrance.

Thanks so much guys, ok corner desk is definitely out. The only reason I wanted floating shelves is because I literally have no accessories display area downstairs it’s all artwork and wall decor. I would like to display awards, graduation photos, my precious globe and so forth. I will look for a free standing desk 1st and then decide on floating shelves

Go with oil option anf\d put shelves above a credenza/bench

Oil?

You can still have floating shelves on that wall seen from front entrance, plus storage cabinets along wall opposite study entrance. Your room ….have it how you want. But it is better to look out of the room when at your desk, not at a wall.

Do it as a library. Two wall as book shelves., a desk on wheels that can be placed as a desk or console table. Aa suitable desk chair that could be a reading use a captain’s chair with a small coffee table, very sophisticated and presentable

You could have adjustable shelves to fit your trophies, globes and mementos. Have it as built ins much more finished than flooring shelves in a formal setting

I have another suggestion: what about a long bench across the window: sit looking out the window for an eyes up from screen look. If you get sun in that window you will have nice warm feet!! Then the other one or both two walls can have cabinets and shelving for frames and globes. I like the idea of a comfy chair for a rest and move away space too. Or anytime reading spot... Go well love to see what you do! Cheers Margot
