Buildable Area Calculator Nepal | How Much Can You Construct?
Estimate how much house area you can construct on your plot using ground coverage (GCR) and FAR. Works with aana, ropani, and Kathmandu-style bylaw inputs.
How this works
plot m² = plot value × unit factor max footprint = plot × (GCR / 100) max total floor area = plot × FAR approx storeys ≈ FAR / GCR (unless overridden)
Worked example
On 7 aana with 60% GCR and FAR 2.5, the calculator converts 7 aana to m², then shows maximum ground footprint and total buildable floor area across floors.
FAQ
How much can I construct on 7 aana land in Kathmandu?
It depends on your municipality’s ground coverage (GCR) and floor area ratio (FAR), plus setbacks and road width. Example: on 7 aana with 60% GCR and FAR 2.5, footprint ≈ 60% of plot area and total built-up across floors ≈ 2.5 × plot area. Always confirm bylaws for your ward before design.
What is the difference between GCR and FAR?
Ground coverage (GCR) limits how much of the plot the building footprint may cover on one floor. FAR limits total floor area across all storeys. A low GCR with a high FAR pushes the house taller.
Does this include setbacks?
No. Setbacks reduce the practical footprint further. Use this calculator for a first ceiling on GCR/FAR, then check setbacks with the Setback Calculator and local bylaws.
Which land units are supported?
You can enter plot size in m², ft², aana, ropani, paisa, daam, kattha, bigha, or dhur — the same units used in Nepal land deals and naapi.
Is the storey count guaranteed?
No. Estimated storeys are a planning hint from FAR ÷ GCR. Road width, height limits, parking, and structural design can reduce what is actually approvable.
