Make a bedroom alcove look custom by treating its opening like architectural detail. Add trim or molding painted to complement the wall or contrast smartly to frame the niche. Use consistent lighting that blends with the room’s palette and finishes. Choose built-in elements sized precisely for the space, like ten to twelve inch shelves or a bench eighteen to twenty-one inches deep, to avoid improvised appearances. This deliberate approach transforms the alcove from an awkward cutout into a stylish feature enhancing room design.
