We are CPWD enlisted, MSME registered, and managed by an IIM Ahmedabad alumnus. Every project we take on is treated with the same rigour, accountability, and attention to detail — whether it's a 1,000 sq ft starter home or a 4,000 sq ft luxury bungalow.

Who We Are
Who We Are
Cestrum was built from a genuine frustration with the construction industry — where verbal commitments replace written contracts, material substitutions happen without notice, and clients are left with half-finished homes and drained savings.

Today, Cestrum operates across residential construction, painting & waterproofing (ColorCrest by Cestrum), and solar installation — serving clients across Lucknow and surrounding areas. Our approach is simple: everything is written, every material is specified, and every rupee is accounted for.

Accountability
One point of contact. One firm responsible for the entire project. No finger-pointing between contractors.
