Steel bridge structure at golden hour

Structural Design Consultancy · Est. 2024

Designing Resilience,
Delivering Excellence.

A New Delhi practice for structural design — quietly shaping the buildings, bridges and infrastructure that move modern India.

Philosophy

A quiet pursuit of structural integrity.

Perennix Engineering is a structural design consultancy founded in 2024, working across commercial and residential buildings, bridges, metro and railway infrastructure, steel and concrete structures, retrofitting, and structural audits.

Our work is shaped by a small, deliberate team — engineers with more than three decades of design experience and draughtsmen with over twelve. Each project is an exercise in restraint: the right structure, sized precisely, built to last.

We design what holds. Everything else follows.

Practice

Seven disciplines.
A single standard of care.

01

Commercial & Residential Buildings

Structural design for high-rise, mid-rise and bespoke residential work — concept through construction documentation.

03

Metro Projects

Viaducts, stations and depot structures for urban transit, delivered to programme.

04

Railway Structures

The Studio

Eight hands. Decades of practice.

Perennix is built around a compact team of eight — design engineers carrying more than thirty years of experience, supported by draughtsmen with over a dozen years on the board. Small enough to stay personal, deep enough to take on the most demanding briefs.
