HI -- Put the wardrobe where you show the desk and the put the desk beside . Now move the bed into where the wardrobe is shown now . Would this work better for you? Better to have all the storage furniture along that one long wall . There might even be some room for another storage piece of furniture .That might open the floor space a bit more for you and also make it possible to add some more lighting .

Basics first, please get rid of any plastic furniture like that chair. secondly all table tops need to be cleared of little mirrors, table clocks etc. just place three most loved items of your choice ! Arrangement can also be improved the table could come on the side and bed could be centred a bit better (along the window behind it). Walls can be painted a neutral shade like light beige with a rug of your choice on the floor (contrasting- like red so that the pink curtains could go with it)If you could change the curtains then the best option would be to pick a solid colour of your choice and a matching rug (blue, red etc whichever is your fav colour but please avoid printed cutrains)

room size is 15 square feeet by 16 square feet. north wall has glass windows

I have a similar issue, i have 3 feet wide & 10 feet long balcony attached to the dining area. It is more like a standing balcony, i plan on adding greenery, and decorate it with some terracotta stuff, pebbles & make it look like an attached conservatory to the dining. My problem is, it is way too narrow a balcony and i want to design it aesthetically. I also plan on adding glass sliding doors and cover the roof top & sides of the balcony with the glass, add some color to the walls to give it a conservatory look. Again, safety is an issue. I need to know if this is feasible and will look good. It is currently under construction. Any ideas & suggestions are welcome!
