This corner cabinet is a box where a portion is unseen when opening the door. This happens when two rows of cabinets meet at the corner but one box uses the extra space that could be lost to the corner but becomes usable space.
Blind corner cabinets take advantage of potential space that would be lost but can be a challenge to reach contents toward the back of the box. There are options that can be designed into the blind corner to make storage more accessible without straining such as the Lazy Susan turntable or a magic corner cabinet, where baskets can be pulled out, normally held in the recess of the blind corner.
