T. Srinivasan, DCE
Director & CEO · 35+ years of experience
S3 is led by Director & CEO T. Srinivasan, who brings 35+ years of experience to every project the team takes on — and the conviction that a home should stand strong creatively and structurally.
From the first consultation to handover, his team of architects, interior designers and civil and structural engineers works as one — so every decision on paper is one the site can deliver.

Sharatheeswaran is S3's Managing Director, with 10+ years of experience. A structural engineer by training, he leads the structural side of S3's work — the load calculations and structural drawings behind each frame, and the stability certificates that approvals require.
With a master's degree in structural engineering and membership of the Institution of Engineers (India) and the Institution of Valuers, he makes sure the homes S3 designs are engineered to stand — and that what is drawn is what gets built.
