Splitting a sunroom into two zones like 60/40 creates designated spaces for different activities, improving function and style. The brighter 60% zone works great as an art studio where controlled natural light enhances painting. The 40% zone serves as a cozy home library or reading nook with softer light and comfortable seating. This zoned layout reduces clutter, allows better furniture placement, protects books from UV damage, and invites daily use of both spaces without crowding.
