It is easy to decor girl and boy bedroom separately. However, some parents may not have enough room for two bedrooms. When having two girls or two boys, shared bedroom is not complicated. In case you have a boy and a girl, you need to apply the delicate design on bedroom.
First thing on girl and boy bedroom is separated the space without partition. In one room, you can divide the space into two equal areas for boy and girl. It is not just the space, but also for both furnishings that have to be equally arranged. There is always counterpart for everything, including furniture. You can use two same beds then add two desks side by side in the middle. Each desk has one chair, and all of them are the same without distinction. To know whether the bed is for boy or girl, use different color on the bed cover. Girl usually loves pink and boy may choose bright blue. As you know, pink is a part of red and the opposite color of red is blue. This arrangement gives balance effect for entire room. For your information, both beds face the same direction, but in different area inside bedroom.
Another way to arrange bed on girl and boy bedroom is different direction. One bed is on the side of wall and another is next to it. Both beds will create space in the corner for storage or shelves. In previous design, boy and girl can see each other easily, but not for this kind of arrangement. It is suitable to give more privacy for them. Moreover, this design gives extra space in the center of room that can turn into area for them to play together.
If the bedroom is long rectangle, the bed can be arranged next to each other with opposite direction. Both headboards will meet then you need to add high partition to recognize the space. Parents can use two bunk beds, but the top area is for storage. Both beds have the same size, but with different decoration. Girl can use the storage to keep the stuff, while your boy may play at the top of bed. This is easer thing to decorate the shared bedroom between your son and daughter. As usual, this design also provides enough space for them to play.
From those ideas, the room size is crucial to put into utmost consideration. When the room looks square with the same width in both sides, first and second designs are preferable. On the other side, longer room is better to use the last design idea above. Therefore, you as parents still have to give privacy aspect when decorating girl and boy bedroom.
