Construction · Project management · Supervision
We build what was designed. Exactly.
From approved drawings to handover, NI Builders runs your construction with in-house engineers, clear estimates and site supervision you can rely on.
Design + build
Design and construction, one team
National Interior designs it. NI Builders builds it. Because both teams sit in the same office in Banasthali, your drawings, estimate and site work stay in step — and you have one point of contact from the first site visit to the day you move in.

How we work
Six clear steps from drawing to handover
You always know what happens next, what it costs and who is responsible.
- 01
Design handover
We start from approved drawings — from National Interior or your own architect — and check them for buildability and cost.
- 02
Estimate & BOQ
A detailed bill of quantities and a transparent cost estimate, agreed before any work starts.
- 03
Naksa pass & approvals
We prepare the documents and follow up with the municipality so permits don't hold up the site.
- 04
Construction
Foundation, structure, masonry, services and finishing, run by our own site team on a clear schedule.
- 05
Quality checks
Material tests, stage inspections and regular photo progress reports, so you always know where things stand.
- 06
Handover
A final snag list, documentation and a walkthrough of your finished building.
