What is indicated by a corner cabinet extension in measurements?

A corner cabinet extension in measurements indicates that only one cabinet extends into the corner. This is a common practice in cabinetry design where a single cabinet, often shaped to fit into the corner, is utilized to optimize space and allow for functional storage. When this is the case, it's important in measurements for installation or design planning to specify that it is a single unit occupying the corner space, rather than multiple cabinets merging into the corner area.

In situations where measurements are taken for construction or remodeling, understanding that only one cabinet extends into that corner can help prevent miscalculations regarding space allocation, design flow, and overall aesthetics in room layout. The other scenarios mentioned, such as having multiple cabinets extend or ignoring standard depth measurements, do not accurately reflect the common practice associated with corner cabinet designs.
