This could go in a lot of different directions depending on your tastes. But if you're living alone, I'd go in a more feminine, romantic direction. So many married women can't get too girly with master bedroom decorating because their husbands are uncomfortable with it. You can! Here are a few ideas to get you started:

If wanting help with furniture and layout, if you could provide your functionality needs, style preference and importantly a diagram with dimensions. For help with basically decor choices, suggest searching small bedrooms on line so you can define your preferred look. Also check ”bedroom mood boards“ on Pinterest as they are helpful around the coordination of an entire space (see below). Think big picture and then drill down to the items used to help with purchasing and limiting mistakes.

Choose the bed linens first, everything else will follow. If you choose that and then are stuck, update your post with a picture of what you've chosen. It is a good idea as Sabrina said to try to determine your style before buying anything. Do any of the pictures she posted appeal to you? An inspiration picture helps to get you started and there are millions of pictures on Houzz that could provide inspiration.

Thank you all for your beautiful advice and attention..l really appreciate it and drawn on it already ..l want to add this the room will be for three girls.. any ideas for wall decoration such wallpaper or for the column decor !? We will need 2beds and big closet.

You need to post a scaled drawing with every wall, window, doorway and every inch noted. Upload it as a very legible. bold jpeg , in a comment box.

You need to add the age of the girls as well - secondary info but FIRST? A scaled drawing that is accurate to the inch

As per Jan, but could you also advise when replying why only 2 beds, as you mentioned 3 girls. Any other needs, ie: desk and you mentioned a closet, is there not one in room?

Once their ages, additional needs, preferred colors and layout/dimensions are provided, you’ll get more relevant advice, as it’s a stab in the dark right now.

The more info you give us the more help you will get. The to scale plan is a must , use graph paper it makes it easier to do scaled drawings. Then we need to know the gaes of the girls. I aslo am wondering why 2 beds not 3 . So post all the added info here in comments do not start another post .

If you don’t have graft paper, just do it on paper and post a picture

The ages of girls is 19 17 11 .Wa think that the bigger wall is for 2 medium beds as we not prefer the double bed, beside a dresser with a mirror..and a big cupboard on the opposite wall ,the corner will be for a library and desks 

any designs for this plan? .. we think to put wall paper on the beds wall or/and to decorate the column .. you have any ideas for it !?

You will not get any answers that help you, until you help the community. Meaning you need a piece of plain paper, a drawing of the room, a measuring tape/USA INCHES, OR CONVERT CENTIMETERS....... and you write in the dimensions on the piece of paper.

Take picture of your drawing with dimensions, upload as jpeg. In a comment box.

Until then?? Nobody will chase you for the information. There are no designs, because it can not happen until you do as above.

A "double bed" IS a "medium bed". Are two going to sleep in one bed?

You have no idea what will reasonably fit in your space, and nor do we. Wall paper??!!! Not yet a question. The first is who shall sleep in what, and where
