Residential Construction in Chennai — G+1, G+2 & Villas

A G+1 (Ground + 1 floor) typically has two separate floors that may function as separate dwellings or be combined. A duplex has two complete dwelling units in one building — either side-by-side or one above the other — sharing a common wall or slab but with separate entrances, kitchens, and meters.

Yes. Even a single-floor house requires proper foundation design based on soil bearing capacity. Skipping structural design leads to cracked slabs, settlement, and waterproofing failures within 5 years — issues that cost far more to fix than the upfront engineering fee.

FSI limits vary by zone: 1.5 for most residential areas, 2.0 for multi-family in some corridors, and up to 3.5 for specific development zones. For plots along widened roads or IT corridors like OMR, special FSI bonuses may apply. Our architects verify your specific plot's limit before design.

A basic quality G+1 (2,000 sqft total built-up) costs ₹32–38 lakh for structure, brickwork, plaster, and waterproofing. Adding standard finishes (tiles, electrical, plumbing, painting) brings the total to ₹45–60 lakh. Premium finishes push this to ₹65–80 lakh.

A per-sqft contract quotes a lump sum based on area. This hides which materials are used and what grade of steel or cement is specified. An itemized BOQ specifies brand, grade, and quantity of every material. If anything is substituted, it is a clear, auditable contract violation.

Yes, if your plot allows a G+1 or higher under the approved plan. Many Chennai homeowners build G+1 with the ground floor as a rental unit to offset construction EMIs. However, the electrical and plumbing systems need to be designed separately for the two units from the start.

Approval is through CMDA (for Chennai Metropolitan Area) or DTCP (for suburban plots). The process involves submitting architectural drawings, site plan, ownership documents, and NOC from relevant authorities. Our empanelled architects handle the entire filing process.
