What makes this bedroom’s design feel cohesive and inviting? To create a cozy environment, it’s important to think inside the box.

Every room has six surfaces: the four walls, the floor and the ceiling. You need to take all six into account when you’re planning a space.

This bedroom has every element needed to make a room feel comfortable. The oak-brown carpeting is almost an exact match for the warm brown walls. Cream and brown bedclothes stay in the same color family while using texture and pattern to keep the room interesting.

The most exciting design decision, however, is the ceiling. By choosing a very dark brown combined with the cream-colored wide crown molding, the sixth surface moves from an afterthought to a powerful design feature.

This is an old fashioned room, from the plates on the wall to the furniture and accessories. But the ceiling is daring and takes the space out of great-grandma’s house to a bedroom that would work in an expensive country inn.

Look up. Are your ceilings white and forgotten? Next time you redo a room, work with all six sides of your box.
