behind ZILA.

Fighting contractor fraud with code. Building the tools I wish existed when my family was quoted 3× the real cost.

I'm a registered civil engineer specializing in hydropower projects. After watching my family get deceived by inflated contractor quotes with no way to verify costs, I built ZILA — Nepal's most detailed preliminary construction cost estimator — so that ordinary families can know what their home actually costs before pouring their life savings into it.

The Mission

Know your numbers before you pour your savings.

In Nepal, the construction industry runs on information asymmetry. Contractors quote wildly inflated prices because homeowners have no benchmark. A Rs. 60 lakh house becomes Rs. 1 crore on paper.

ZILA gives you a detailed Preliminary BOQ — a phase-by-phase breakdown of what your house should actually cost, built on real district-level material and labor rates, and enforcing NBC 105:2025 seismic standards. Walk into your contractor meeting informed.

Every Rs. 199 report funds server costs, data verification, and keeps this tool free to explore. You're not buying software — you're funding transparency for every Nepali family building a home.
