I'd choose something of simple and light design.

Ikea have a headboard which you can fit behind your own bed and eliminate the bedside units gaining more space for nightstand use and quilt storage underneath. It will give you some more privacy from the window too. Eventually a roman blind would be more appropriate too. The remaining wall at the side of the window can be used for hanging shelving like the ikea kallax. Open the space visually by simply adding a larger mirror to a side wall and hang hats scarves and even coats on pegs along the opposite wall. Use the space above the entryway door for shelving or closed cupboards and fit in a corner wardrobe. If you can remove the door or get it to swing outward. If you consider changing the bed for an underbed storage one it must have a hydraulic mechanism otherwise it is a nightmare. But you can find some storage bags or boxes that slide under the existing bed - just measure properly and try to make the best of the space. Alternatively you could change the bed completely to a high up loft base with a ladder and have ample space beneath it. Check the ikea Stora and others too.

How much are you able/ prepared to do on the stairs? You could have the steps re-tiled, or carpeted, laid with wood and a carpet runner, and you could install a new handrail if you have a larger budget. However, if you want to work with what you've got, I would focus on the tiles. I don't think the handrail itself is a problem- it could do with a lick of paint, but the tiles are a little dated. You can paint floor tiles but you'd need to be very careful to make sure that they were done safely to avoid slips on the stairs. Alternatively, you could have a stair runner fitted, to cover up most of the tiles, and then put some colourful artwork on the wall at the back to draw the eye upwards and away from the tiles. I hope it goes well- post us some pics when you've finished. Best wishes, Kate www.TheHomeDesignSchool.com
