42. Housing unit's floor area (square meters), Question 51
Housing unit's floor area means the total built area with roof in the housing unit like a room, kitchen, bathroom, toilet, storage, pantry, closet, etc.
In apartment building units, the unit's floor area means the area of the unit excluding the common areas like garage, pilot, corridor, stairs, etc. In these units, all the spaces related to the unit are considered for the floor area, even if they are located outside of it, like storage.
In housing units other than apartments, all the built areas (like the garage, corridor, etc.) are included in the floor area.

Ask the floor area in square meters and mark the relevant box. For example, if the unit is 49 square meters, mark box 1, and if the floor area is 105 square meters, mark box 5. If the respondent is not aware of the floor area, with his help and the geometric shape and dimensions of rooms and other parts of the unit, try to calculate the floor area and mark the appropriate box.
