Before you build: the land evaluation checklist

Most expensive mistakes in a house build happen before construction starts — at the moment the land is chosen. This is the checklist our engineers run on a plot before we agree to design on it.

1. Papers first: ownership and boundaries

Ask for the Lalpurja (land ownership certificate) and match it against the trace map / blueprint from the Survey Office. What we verify:

2. Legal access to the plot

A plot without a registered access road (bato) can be nearly impossible to get a building permit for. Confirm the access shown in the trace map physically exists and its width meets the local municipality's minimum — commonly 4 m or wider for a permit in Kathmandu Valley municipalities, and more if you ever want to go tall.

3. Ground you can trust

Rice-field fill, old pond beds and river-edge plots behave very differently under a two-storey load. Signals we look for on site:

For anything ambiguous we recommend a soil test before design. It costs a fraction of one percent of the build and decides the foundation type honestly.

4. Services: water, power, drainage

Check the practical distance to the nearest water line, transformer and — most forgotten — where the plot drains. A plot lower than the road will pump sewage uphill for the life of the house.

5. Setbacks and what you can actually build

Every municipality enforces setbacks from the road centreline, river banks and high-tension lines, plus a Floor Area Ratio (FAR) and height limit. A 4-aana plot does not mean 4 aana of ground coverage. We run the numbers before purchase so the house you imagine is the house the rules allow.


Bringing a plot to Treta before you buy it is a service we genuinely enjoy — a one-visit review is cheap insurance. Start a conversation.
