A G+1 house plan (Ground + First Floor) is the most popular residential configuration in India. It doubles your living space without needing a larger plot. Whether you want a unified family duplex or two independent floors for rental income, the G+1 format offers unmatched versatility.
At PlanMyPlot, we design G+1 houses in two distinct modes: "Integrated Duplex" (internal staircase, shared volumes) and "Independent Floors" (external staircase, separate entries, ideal for rental income of ₹8,000-15,000/month). Both modes are fully Vastu-compliant with proper vertical zoning.
The G+1 format adapts to almost any plot size and family requirement. Here are the most requested configurations:
Vastu on a G+1 structure requires vertical alignment. Rooms must be zoned correctly on both floors:
A G+1 construction essentially doubles the built-up area. Here is a breakdown by plot size:
| Plot Size | Built-Up Area (G+1) | Standard Cost | Premium Cost |
|---|---|---|---|
| 20x30 | ~1000 sq ft | ₹18 Lakhs | ₹25 Lakhs |
| 30x40 | ~1800 sq ft | ₹32 Lakhs | ₹50 Lakhs |
| 40x60 | ~3500 sq ft | ₹60 Lakhs | ₹90 Lakhs |

If planning for rental income, use an external staircase to give each floor complete independence.
Place the plumbing stack vertically aligned on both floors to reduce plumbing cost significantly.
Use a common structural grid so that columns and beams are consistent across both floors.
The first floor slab should be designed to support a future second floor expansion (G+2).
Consider separate electrical meters from the start — it saves significant rewiring costs later.
