Definition
A mezzanine is an intermediate floor in a building, open to the floor below. Think of it as a 'half-story' or a low-ceilinged story positioned between two main floors. It's typically smaller than the main floors and often projects as a balcony. Imagine a bookstore with a small upper level overlooking the main floorβthat's a mezzanine! It adds architectural interest and creates extra usable space without being a full floor.
