An instagram style wall - small white square picture frames hung evenly in rows from height of computer screens upwards, with some of your favourite candid pictures. would look good all printed in b&w, or sepia to tie in with your colour scheme...or alternatively go bright and vivid! summer beach shots, pets, kids, holidays etc

I’m set up in our sunny spare bedroom. Happy with my spot as I have views to the street and a desk to work from.

That's a great unique desk. I wouldn't put too much on it so you don't have too much to move when you need to work. Are you planning to hang any art? I think the wall behind to the right could use something. And an item in a coordinating colour on the left of the desk, like maybe a pen holder from a craftsperson who makes timber or glass? Or is the space between the windows where you're putting the bookshelf?

Also if i can avoid moving air con for now that would be great. The next phase of reno will be to take down the wall between lounges and put aircon on the front wall of the lounge as it's the only other outside wall it can go on. Here might be my plan for now. I'll put the kitchen in place and figure out if i need to add more storage to office area. Will add range hood and a few long open shelves like in the image below (and is also the look i'm going for decor wise)
