My setup is that I had a media room and study built together as one room, but there is a clear division with a bulkhead into 2/3 media and 1/3 study. Could be considered a multi purpose room or formal dining if a buyer has no need for study/media. I want to have some kind of sliding door or bi-fold door or something proper if I want to close the study off.
I intend to have a desk built to fit the size, could seat up to 3 people across, but ideally only 1 or 2, and there are double power points on the 20 centimetre long walls (lined up with the bulkhead) on each side of the room , and data. Currently I just have my shithouse ikea desks. So the desks in the study face the TV in the media room.
The back wall of the study - well I would like to put a light tone-on-tone wallpaper and cover it with transparent magnetic paint and transparent plastic, so the whole wall would be like a magnet-board AND a whiteboard, at least above desk-height and not counting any shelves, etc...
I would get the same wallpaper pattern but in a dark colour and use it on the media room wall behind the tv.
Here is a shot from the media room looking into the study. Pretty fucking plain right now, but you get the idea of the layout.

This 'desk facing tv' is essentially something I started when I was 13, and when I lived in various townhouses and apartments I'd basically just set up the living room to be like my old bedroom, and now I have a room in the house especially for this and it's where I live.

I regret the middle window
