What smart hacks work for decorating hard-to-reach under-stairs spaces?

Smart hacks for hard-to-reach under-stairs spaces include installing pull-out trays for tall plants, mounting mirrors to reflect light, or converting the nook into a pet lounge. These focus on low-touch accessibility from the stair edge, avoiding the need to climb inside the nook. If storage is needed, adding a hidden door from another room grants full access without compromising stair-facing openness.
