First, I love an alcove bed. Thomas Jefferson did too. Tremendously cozy and a stunning architectural detail in a room. I've always wanted one.
Second, this one above is a FANTASTIC idea for a small bedroom. Using one wall as an anchor for the bed and built-ins makes the room so functional and completely special. The mattress can sit on top of built-in drawers that provide storage allowing you to free up floor space. And built-in bookcases provide room for display and additional storage. Such a great idea.
I love how this particular nook is layered with textiles - curtains, an upholstered headboard, a roman shade. And the darling details of the sconce and artwork. The dolls are slightly creepy. But the space is charming and lovely for a child.
I'm all for sleeping right up on a window like that too. I need natural light to wake me up (and almost never mind it even when I'm trying to sleep in). But maybe you'd be anti-window, in which case, this works on any ol' wall.
I need an alcove bed in my house at some point. Definitely holding on to this image as inspiration.
