How to Make a Windowless Room Feel Open

Cover the windowless walls with a light pastel or an off-white paint, then paint a bold accent wall in bright yellow to simulate the missing sunshine.

Use metal and water to reflect light on a wall. Hang a polished copper or steel water fountain on a wall. Add a mirror to the wall across from the room entry to create a sense of expanded space.

Furnish a windowless room with light-colored contemporary or lightweight pieces. Use a sofa and chair with low backs and space beneath the furniture to create spatial flow. Add tables with glass tops.

Select and arrange just a few pieces on tables. Place a vase filled with a simple and bright floral arrangement to bring the outside in.

Use artificial light to reflect light into the windowless space. Point light to reflect off the ceiling with sconces.

Utilize the light from another room by opening an interior wall to add spaciousness. If it is an option, cut an interior window into a wall that leads into a room that does have a window.
