A weird bedroom alcove becomes valuable when you assign it a single clear purpose and use dimensions thoughtfully. Popular uses include a vanity, built-in shelves for books or linen, a reading nook, or a mini closet with a tension rod and curtain. Aim for shallow shelving between ten to twelve inches deep and bench seating around eighteen to twenty-one inches deep. Adding warm, well-matched lighting and finishing the opening with trim or paint turns the nook into a stylish feature rather than wasted space. Start small — a single shelf or mirror — then build from there to make it your favorite spot.
