Avoid overcrowding a bedroom alcove by assigning it too many functions at once, like combining a vanity, closet, and reading nook simultaneously. Steer clear of using furniture pieces wider or deeper than the space allows—over twelve inch shelves or benches exceeding twenty-one inch depth typically look cramped. Poor or no lighting also weakens alcove usability and appeal. Instead, choose a clear primary use, keep elements shallow and well lit, and add architectural trim to unify the design for best results.
