How do I avoid clutter when decorating under-stairs spaces?

Avoid clutter by editing down to one clear, calming idea in the under-stairs nook. Resist packing in bookshelves or multiple furniture pieces. Instead, choose a standout element like a single plant, mirror, or a pet lounge. Maintain thirty to fifty percent negative space to ensure openness. Keep decorations low-touch and accessible, prioritizing safety, light preservation, and peace of mind.
