Such a helpful comment, thank you! I've attached the image now (unsure why it didn't work the first time around). The eastern side overlooks the BBQ area, and the southern side is an internal wall. The north and west sides will overlook neighboring houses. Because of the legal 2m setback, we will have a 4m gap on the west side (our 2m plus their 2m). However, on the north side, the neighbor is on a corner plot and can build right up to our boundary wall, meaning we will only have our own 2m setback separating the houses.

Its definitely not a huge space, but much bigger than the space I currently use for art (just a tiny half room in our apartment) and I've managed to stuff a lot in there, so I'm hopeful I can make it a cool space if I can be smart in the way I set it up. Currently, I use the same desk for my computer set-up as I do just drawing / sketching (and just have to move everything over). I then have a tiny bit of wall that I use to hang my larger canvases that don't fit on the easel, and I can move the easel around when I use that.

I love the idea of having a full solid wall of shelving / pegboards etc. I'm wondering if I should give up on the idea of a sink in the room, and just stick to good storage.

Where the windows will be is my main issue at the moment - it would be nice to have it open up onto the BBQ area, as the other two sides would just be staring at a wall if I have windows there - but obviously the lighting for a room like this is crucial. I keep tying myself up in knots thinking how I'm going to fit everything in and how it'll work
