4 Basic information required for computing gross floor area
4.1 Site Area
The site area is the area of a development plot measured between the survey boundary lines. The boundary line defines the
legal ownership of the property or development site. The development plot could either sit on a full lot or on a part lot.
If there are areas within the development site to be vested to the State, for example for road widening or drainage purposes,
these areas can be included as part of the development site for plot ratio calculation. Once these areas are vested to the
state, they cannot be used for plot ratio calculation, subsequently.
4.2 Plot Ratio
The plot ratio of a site is defined as the ratio of the gross floor area of a building(s) to its site area.
4.2.1 Proposed plot ratio
The proposed plot ratio as declared by the qualified persons in the EDAform/application form. Generally, this plot ratio
is not allowed to exceed the current Master Plan plot ratio.
4.2.2 Allowable plot ratio
The allowable plot ratio is the prescribed plot ratio in the current Master Plan.
