holly, look at the 3rd pic I posted w/the gray duvet, to keep it from looking too dreary, bring in a large white rug, some natural wood items, maybe the ikea white vanity (it's shallow) and lots of plants. look into a tapestry gray/white duvet cover and then do the solid gray curtain. ikea vanity (or the one jansgirl posted) , wood accents, and maybe some gold, like that lamp jansgirl posted. gray drapes like these and notice the natural wood elements. dark gray throw, gray velvet pillow shams, fluffy white rug,,etc.

So I just tweeked your current plan a little bit by doing pier style cabinets on either side of the bed. Then you don’t have to have a nightstand. Or you can just do full height wardrobes. You will have to account for the jogs in the wall so that the bed is positioned so that you can get the doors open. Then the desk would be opposite the bed and possibly add a little bookcase. I am showing a queen sized bed.

If you have someone who is handy, you could get them to build you a cover for that radiator and have it extend over towards the bed with open shelves on the end. Something that looks like this. I'm struggling with importing the pictures. Have a look at that website. There is a picture of a cover that has open shelves at one end - something like that might solve mulitple issues for you. Or, similar to that, it could have a little drawer and door so it would be more like a proper table and then the top of the rad is also a bit of storage for you. This is a Canadian company but the pricing looks quite reasonable IMO. I'm sure you could find someone local to you who could build something similar.

My 6 yr old loves his Kura reversible loft bed with canopy from Ikea. He and my 3 yr old both enjoy having a ready made tent! https://www.ikea.com/us/en/catalog/products/80253814/ We have it in his 11'6" x 10' lengthwise along the 10'wall. It can be a normal bed or you can flip it into a mini-loft bed. In the loft bed mode you can put a mattress under it and create a bunk bed. We have it now as a normal bed since he just started regularly sleeping in it and have the jungle canopy on it. Length: 78 3/8 " Width: 41 3/8 " Height: 45 5/8 " Height under loft bed: 32 5/8 "
