How many plots can this land be cut into?
Give the road facing width and the depth of the land, or its total extent, and the plot sizes you want. You get the plot count, the plot size, the internal road or passage it needs, whether it is a sub-division or a layout, and the open space the rules take.

The answer
Worked out from the figures you gave, with the rule behind each number.

- The passage or internal road sized by the local body rules
- Plot count at your chosen size, not a generic yield

Cutting land into plots, briefly
A sub-division splits land into a few plots served by an existing road. A layout is a larger division that needs new internal roads and open space, and full layout approval from DTCP or CMDA.
- Smallest plot
- 72 sq.m
The smallest regular plot the building rules allow, and the lowest size this calculator will cut to.
- Shape decides
- Frontage and depth
The same extent gives very different counts at different frontages, so the width and depth matter more than the area.
- Open space
- Above 3,000 sq.m
Land over 3,000 sq.m reserves 10% as open space or pays the fee in lieu. Above 10,000 sq.m the land must be given.
How to work out the plots in a piece of land
- 1
Enter the size
The road facing width and the depth in metres. If you only know the extent, enter it with its unit for a rough upper count.
- 2
Set the plot sizes and road
Give the smallest and largest plot you want (1,200 sq.ft is about 111 sq.m), the width of the road the land faces, and the local body.
- 3
Read the patterns
Each pattern shows the plot count, the plot size, the road it needs and how much of the land it uses.
When it helps with land
Before buying land to plot
Know how many sites the land yields before you agree a price, not after the surveyor draws it.
Sub-division or layout
See whether the cut stays a sub-division on the existing road, or becomes a layout that needs roads, open space and layout approval.
Family partition
Try different plot sizes to see how the land could be split into road facing shares before the family agrees a partition.
This is a planning estimate from the building rules, not a sanctioned layout. The approving authority fixes the final plot pattern, roads and open space, and the survey sketch can change the sides. Have the land surveyed and the layout approved before you sell or buy plots.
Questions people ask
How many plots can I get from 1 acre?
It depends on the shape and the plot size, not the acre alone. Enter the road facing width and the depth with the plot size you want. With only the extent, you get an upper count that leaves out roads, so the real number is lower.
My land is irregular.
The calculator treats the frontage and depth as a rectangle. For an irregular piece, use the average width and depth, or the total extent for an upper count, and have a surveyor confirm the pattern.
When does it become a layout instead of a sub-division?
When the cut needs new internal roads, or has more plots than a sub-division allows, or the existing road is too narrow. The answer says which it is and why.
Why is the count lower than the area divided by the plot size?
Internal roads, passages and the open space reservation all come out of the land first, and the rules limit how deep a plot can be for its width.
Is there a limit to the plots it shows?
Yes. It shows up to 8 plots for a sub-division and 20 for a central road pattern, so a large site can hold more than the count shown. It says so when that happens.
Is this free?
Yes.
