Love the built-in headboard idea here. Also, white paint and textiles throughout an attic or any other small space can do wonders for making it feel more spacious.
This room is gorgeous sans furniture! Add the big comfy bed? Priceless! the large windows help to brighten the space-but I'm worried about the nighttime. Would it be too dark? I'd love to see two little chairs and a cute end table rather than the couch-but none-the-less this room is beautiful.
