Maximizing FSI & Spatial Flow in Chennai Urban Plots

With land values at a premium across Chennai neighborhoods like Anna Nagar, Velachery, Medavakkam, and Porur, constructing a duplex allows homeowners to maximize the permissible Floor Space Index (FSI). Silux designs vertical architectural duplex homes that deliver open-concept, naturally lit living areas while maintaining private bedroom zoning on upper levels. Our structural engineers design robust RCC column networks adhering to Chennai’s Seismic Zone III requirements, ensuring that interior spaces can have open spans without obtrusive center columns.

Statutory & Regulatory Oversight

All architectural planning and structural blueprints are coordinated directly through CMDA (Chennai Metropolitan Development Authority) & Greater Chennai Corporation (GCC), guaranteeing seamless utility connections and bank financing.
