This room divides the space in an interesting manner. The wooden panel stretches across the ceiling and the wall and then turns into a small reading corner. Such a division of space makes the other part of the room free for other purposes. Thanks to the panels, the bedroom is cosier and more pleasant for the eye.
The green color makes the interior more fresh and energetic. Green accessories in cramped spaces are a bonus.
And an another idea for the same interior. The wall was well-used - there's additional space to store stuff.
