I think the advice about not making it a surprise is sound - but perhaps you could put some ideas together (even on Pinterest or as actual 'vision boards') so you have a starting point (even if she totally rejects everything - at least you know what she doesn't want!). Has she finished school? If she is starting Year 12 next year, or university studies, the desk and chair don't really look adequate for long hours. Consider an ergonomic office chair from Officeworks and possibly some floating shelves attached to the wall, strong enough for textbooks, folders and so on - even to take a small computer printer? Think about a powerboard (with safety switch) to go into the electrical point where the lamp currently plugs in - for the lamp, a computer, a printer, and any other electrical gizmos she has. If she's not studying, how about a large wall mirror for over the desk (rather than on it) and making a lovely dressing table space? (I know when I was 17, trying to dry my hair and experiment with new makeup looks in the family bathroom was not easy!). Good luck with it all, and I hope she (one day!) appreciates what a considerate mum she has!

Hi Lachie - I assume you have a built-in wardrobe on the wall where the door is? (where the photos were taken from?). I'd suggest combining some of the elements of the suggestions above, but orientate the bed so that it's facing the door when you walk in, then put your desk under the other window. You can then put the bookshelf on the other side of the desk, which might leave you enough room for a beanbag/comfy chair in the corner for reading? Otherwise, you can put the bookshelf under the floating shelf (not ideal I know). I'd leave the bookshelf upright so that it's taking up less floor space, and get yourself a beside table (preferably one with a drawer and a shelf below for extra storage). A rug would be great for pulling the space together, but you might run into some issues with your desk chair getting caught on it, so you'll need to think about that. But if you do get a rug, I'd try to match it to one of the blues in your bedspread. Maybe also think about getting a new lamp - something in pink to pick that up from the bedspread (and maybe wood instead of metal to bring some texture into the space). As jmm1837 says, some more art on the walls would be good and will help pull the colours together. I see you have a plant there already, what sort is it? Maybe put it in a small wooden or mint green pot and if you get a wide bedside table you could put it on there (which would put it in optimal light under the window). If you want something bigger which is pretty indestructible, you could try a dracaena, next to your desk would make a nice feature. You might want to think about painting the floating shelf too in white? Few other ideas: cushions for your bed; a throw rug; a vignette of glass/vessels for the floating shelf; if you have space (hard to tell) a chest at the end of your bed (as long as that doesn't mean you walk into it coming through the door) for additional storage/seating; and think about a few plants, not just one if you can. In general I'd try to bring some wood elements into the room to make it a bit more homey. Have attached a couple of quick layout possibilities for fun :). Would love to see what you end up doing!

Do a rough sketch and post it. Hand drawn is fine, don't forget measurements.

The bed needs more pillows with texture and patterns. Add black highlights in the accessories. Also get a lamp for the side table and a tray for accessories etc candles, vase. A few accessories for the desk like a hand-shaped jewelry holder etc. The things that will make the room less boring will be a rug with a visually appealing and exciting pattern (not a solid colour), a chair (the more interesting the better) , new bedding will create a focal point and accessories for the side table and desk. Go to freedom or adairs etc and they'll be staff members to help you choose out furniture, accessories, bedding etc. Show them your pictures and speak to them and they'll know how to help.
