What is finished floor level?

Finished floor level (FFL) refers to the final height of a floor after all construction and finishing processes have been completed. It is the level at which the finished floor surface, such as tile, carpet, or hardwood, will be installed. FFL is crucial in construction and design as it ensures proper drainage, accessibility, and alignment with other architectural elements. It is typically measured from a predetermined reference point, such as the top of a foundation or slab.
