D1 Floor area of the housing unit
Density of occupancy in terms of floor area per person is a measure of the adequacy of housing. In line with the aim of housing policy to provide adequate housing space to a level consistent with the maintenance of health of the occupants, it is important in planning to adopt housing standards.
The data on floor area will provide planners information on the current status of the density of occupancy of existing housing units in the country.

Floor area refers to the space enclosed by the exterior wall of the housing unit. In case of several floors, get the area of each floor in square meters or square feet and add together to get the total floor area of the housing unit.
There are many ways in approximating the total floor area. You may use any method which is more convenient to you. You may use a meter stick, visual approximation (using your eyes only) or your pace factor (see Appendix 4). In case the respondent does not know the floor area of the housing unit, you can approximate the floor area using any of the above mentioned methods. Familiarize yourself with the length of a meter so that you can do visual approximation.
An example of getting the estimate of floor area is shown in Illustration 7.3. In this illustration, it is assumed that the width and length of the floor spaces are already determined using one of the methods discussed above.
To get the estimated floor area (EFA) of the around floor, use the following formula:
EFA ground floor = 10 meters x 7 meters = 70 sq. m.
Using the same procedure for the second floor,
EFA second floor =10 meters x 9 meters = 90 SQ. m.
To get the total estimated floor area of the housing unit, which will be the answer to the inquiry "What is the estimated floor area of this housing unit?"
