Number of building stories

The number of stories of a building includes all above-ground stories (including technical stories and stairwell stories) and semi-basement stories, excluding the attic story.

NOTE 1: The stairwell story is not included in the number of building stories when it only serves to enclose the stairwell/elevator shaft and shelter the building’s technical equipment (if any), and the area of the stairwell roof does not exceed 30% of the roof floor area.

NOTE 2: Only one mezzanine story with a floor area not exceeding 10% of the built floor area of the story immediately below and a total floor area not exceeding 300 m2 is not included in the number of building stories when it only serves as a technical area (technical floor of the swimming pool bottom, floor for generator or other technical equipment of the building).

NOTE 3: For buildings with different ground levels, the number of building stories is counted from the lowest ground level according to the approved master plan.
