The most common question we get from families planning a new home is simple: what will it actually cost per square foot? As of 2026, basic construction in Chennai runs roughly ₹2,000–₹2,150 per sq ft, standard construction (the most commonly chosen tier) runs ₹2,250–₹2,500 per sq ft, and premium construction with higher-end finishes runs ₹2,600–₹3,000 per sq ft.
Location changes the number too. Central Chennai localities like Anna Nagar or Adyar typically run ₹2,800–₹3,500 per sq ft, while South and West Chennai — Tambaram, Padappai, Chromepet, Pallavaram, and the GST Road belt — usually come in lower, around ₹2,100–₹2,400 per sq ft for standard-quality construction, simply because land and logistics costs are lower here.
These rates typically exclude land cost, compound walls, landscaping, and interior furnishings, and you should budget separately for CMDA or local-body approval fees. The single biggest lever on your final number isn't the builder you choose — it's the specification: floor finishes, kitchen fittings, and bathroom fixtures can easily swing a project by ₹300–₹600 per sq ft on their own.
Our advice to every family starting this process: ask any builder for a detailed material specification sheet alongside their per-square-foot quote, not just a single headline number. A quote without a specification is a promise you can't hold anyone to later.
