A dependable partner for enduring infrastructure
Sthirn Projects Private Limited was incorporated in 2025 at Nidadavole, Andhra Pradesh, under directors Naveen and Lakshmi. Behind the new name is the team, fleet and railway track record built up under Thaponishta Constructions since 2010 — and in earthworks since 2004.
We take on the role of main contractor for small and medium projects and execute civil packages for larger ones: station buildings and RUBs for the Railways, warehouses and roads for industry, canals for irrigation. Our clients get an “I am assured” experience — clear communication, close supervision and a programme we keep.
