Why is preserving light important in under-stairs space design?

Preserving light in under-stairs design enhances safety and serenity by preventing dark shadows and cramped feelings. An open riser stair with a mirror accentuates daylight, making the nook feel larger and inviting. Light preservation avoids visual clutter and helps the area serve as a calming vignette rather than a cramped storage pit. Prioritizing daylight keeps the space accessible, safe, and pleasant.
