The overlapping of elements in space.

The principle of layering uses overlap and aggregation to develop more sophisticated solutions that resonate in a design. Layers can be both vertical and horizontal planes, or can be dimensional objects that cover or obscure each other visually to create a more complex composition.

A designer works with layers by treating each space as a blank canvas, and layering occurs in many design strategies and solutions. It is a spatial idea in addition to the two-dimensional overlapping of elements such as flooring and wallcoverings. Moving objects closer together can make spaces appear cozier, and having fewer layered spaces has an lightness to a rooms appearance.

A designer works with layers by treating each space as a blank canvas, examining the surfaces that make up the room and making decisions about their hierarchy and identity in a place. By adding objects against that established background, fixtures such as built-in millwork and larger furniture set the tone of the space and suggest movement through it. Smaller objects, artworks, and textures further strengthen the sense of depth that layering provides.

Views through rooms can also emphasize layering, with doors, windows, and other openings acting as a layering of volumes, which can emphasize contrasting light and dark tones. They can also appear closely linked through the use of similar materials and complementary furnishings.
