How Much Does a Terrace Garden Cost to Build in India? in Mumbai
A terrace garden in India costs ₹200–800 per sq ft to set up, depending on waterproofing, drainage system, soil type, and plant selection. A 200 sqft terrace garden costs ₹50,000–1.5 lakh.
- Basic (pots + railing planters): ₹100–300/sqft — No waterproofing change needed
- Raised bed garden (50–150mm soil): ₹350–600/sqft — Includes drainage layer
- Full terrace garden (200mm+ soil): ₹600–1,200/sqft — Structural check needed
- Premium (landscaped + irrigation): ₹1,000–2,500/sqft — Automated drip, hardscape
Terrace gardens add 150–300 kg/sqm load to the roof slab. Get a structural check before installing deep soil beds. Standard RCC slabs handle 200 kg/sqm live load — shallow planters (under 150mm) are generally safe without extra assessment.
- Waterproofing (if not already done): ₹60–150/sqft
- Root barrier (HDPE membrane): ₹15–25/sqft
- Drainage layer (LECA/perlite): ₹20–40/sqft
- Growing medium (cocopeat + compost): ₹30–60/sqft
- Drip irrigation system: ₹8,000–25,000 total
