20×30 house construction cost in Hosur

After applying HTM's standard setbacks — 1.5 metres on the front, 1 metre on each side and rear — the usable ground floor interior on a 20×30 plot is roughly 17 feet wide and 27 feet deep (about 459 sqft per floor). That is tight but workable. A 2 BHK with a combined living and dining area fits well. A 3 BHK can be done but the rooms will be small — typically 9×10 feet or less. Most builders on this plot size choose a comfortable 2 BHK with a dedicated kitchen rather than squeezing in a third bedroom.

Street parking or a compact car porch at the front is usually the only parking option on a 20×30 plot. A full one-car garage requires at least 18 feet of width after setbacks, which leaves almost nothing for the house on a 20-foot-wide plot. The most practical arrangement is a small stilt parking area that doubles as the ground-floor entry, with living space starting above. This is a common approach in Hosur's older residential layouts near the bus stand and Sipcot areas where 20×30 plots are more frequent.

The cost figures here are for civil construction only — structure, masonry, plastering, flooring, MEP, and a standard elevation. Modular kitchen, wardrobes, and compound wall are separate. On a ₹15–₹17 lakh standard build, the split is roughly ₹5.7–₹6.5 lakh for civil structure, ₹4–₹4.5 lakh for finishes and MEP, and ₹1.5–₹2 lakh for elevation and approvals. Interiors (kitchen, wardrobes) typically add ₹1.5–₹2.5 lakh on top of the civil cost at this size.
