Work out plot subdivision layout instantly with clear inputs, formula shown and shareable results.
A plotted layout must surrender land for roads and open space before any plots can be sold. Roads typically absorb twelve to eighteen percent and open space ten percent by regulation. Dividing what remains by the target plot size gives the yield, which is the number that drives the whole feasibility.
Net saleable area
Net = total area x (1 - road share - open space share)
Plot yield
Plots = floor(net saleable area / plot size)
Preliminary estimate only. Layout standards for road width, open space and plot dimensions are set by local development control regulations.
Net = total area x (1 - road share - open space share). A plotted layout must surrender land for roads and open space before any plots can be sold.
Geometry. Corner plots, irregular boundaries and turning heads waste area that a percentage calculation cannot see, so a real layout typically yields five to ten percent fewer plots.
This calculator takes 4 inputs: Total land area, Land for roads, Land for open space, Individual plot size. The pre-filled defaults are a realistic worked example — replace them with your own site or project figures.
