What does "finished floor elevation" refer to in architectural plans?

Finished floor elevation refers specifically to the measurement from a predetermined reference point, often the grade level or existing ground level, to the surface of the completed floor. This measurement is critical in construction and architectural plans as it determines the height at which the floor will sit within the overall building design. It ensures that rooms and spaces are constructed to the required height for functional and aesthetic purposes, such as ensuring proper drainage, accessibility, and alignment with other structural components. This definition highlights the importance of accurately establishing the finished floor elevation to meet building codes and to achieve the desired design outcomes.
