I would custom build out the corner recess using a wall shelf box and then drop it down under the window all the way behind the door. Or alternatively box it out up until the window and then add in a slide out bedside for your guests to use if necessary. It would mean sitting the entire bed forward and inline with the current left bedside but it would add symmetry, storage and a new designer look. I don't think 2 bedsides are absolutely necessary and you could take away the left one just adding a pendant light as the back would now be a place to sit a glass of water or other must haves.

I would be really disappointed also, glad they are sending someone to look at it, as you said for such an expensive item the workmanship should be spot on, the stores response was not very helpful also, hope the manufacturer fixes it for you as it will always make you unhappy every time you look at it. They say you get what you pay for but in this instance you certainly didn't, best of luck.

Hi amggjo, Here's some bedhead examples and paint colours to inspire you .... have also thrown in a wooden bed head pic as something different to add another textural element :)

You will need a width of 500mm to 600mm for clothing. You will need a walking space of 800mm to 900mm. Therefore you need approx 1500mm space plus width of dividing wall. Having two levels of hanging is quite common. You just install two rows of rails, either with or without a dividing shelf. You mentioned to hang from ceiling. I'm not sure exactly what you mean. Re the wall, contact are carpenter, and they could build dividing wall out of wood and gyprock. Or you could just have a full length curtain installed behind bed. Maybe less expensive and will not take up as much space. Would also form an interesting bed head.
