Unless you’re going for an ultra minimalist look, bare white walls in a bedroom can feel more stark than luxurious. Embrace a little paint or wallpaper to give your bedroom a warmer, more designed look.
As for lighting, I prefer warm, non-directional dimmable light such as cove light or from under a nightstand, and I hide outlets so the design isn't interrupted. I use artwork as an accessory to complement the overall design. And accessories like a carafe, a tray for jewelry, and books can make it feel more personal.
This finished bedroom, with planning and execution, took four months. The nightstands were custom, the wallpaper handmade, the bedframe, furniture, rugs, lighting and accessories took months to arrive from our vendors. Then we had to consider the electrical work, painting, application of the wallcovering, and the installation of the furniture. The takeaway is that a well-done room takes time, planning and patience, but the outcome is worth waiting for.
For an unexpected headboard, use a decorative element that’s not typical for a bedroom. Consider painted wooden window shutters, a decorative wall divider that can lie flat and be attached to the wall, or an ornate iron panel painted a fun color. Just make sure to place oversized pillows in front of this kind of installation or hang it where your head can’t touch it.
