Quality of Materials
Material choices play a decisive role in the overall budget. Prices of cement, steel, bricks, sand, tiles, and fittings influence the final material cost of house construction in Chennai. Opting for premium brands increases longevity but also raises costs.
Design Complexity and House Size
Complex architectural layouts, duplex structures, or luxury villas significantly increase costs. For example, the cost of building a luxury villa in ECR Chennai is substantially higher due to bespoke designs and premium specifications.
Labour Costs
Skilled and semi-skilled labour availability affects timelines and budgets. Rising wages have increased the labour cost for house construction in Chennai, especially for finishing works.
