How can I use under-stairs space effectively without clutter?

Using under-stairs space effectively means focusing on calm, low-maintenance designs that honor light and safety. Instead of crowding the nook with bulky furniture or complex storage, opt for simple ideas like a single tall plant on a pull-out tray, a gleaming mirror to double daylight, or a small pet lounge. These choices maintain openness, keep the nook accessible from the stair edge, and transform dead space into a stylish focal point without clutter or maintenance headaches.
