Unlimited FSI: India Needs More Skyscrapers
Introduction: Addressing India's Urban Challenge
By 2030, India’s urban population will reach nearly 600 million, intensifying the urgency to adopt smarter, more efficient city planning strategies. The Floor Space Index (FSI)—the ratio defining permissible building heights and density—is central to shaping urban growth. Higher or unlimited FSI enables vertical growth, offering a strategic solution to affordability, infrastructure efficiency, and economic vitality. Hyderabad’s decision to adopt an unlimited FSI policy since 2006 demonstrates how Indian cities can effectively manage population expansion and economic development sustainably.In this extensive guide by Landeed, we deeply analyze the urgent need for higher FSI across India’s metros through detailed city comparisons, practical life scenarios, global benchmarks, rich data insights, and robust counterarguments addressing common concerns about high FSI, reinforcing the compelling case for embracing vertical urbanization.
Comprehensive Understanding of FSI in Major Indian Cities
FSI across major Indian metros significantly varies:
- Mumbai: Residential (1.33–3.0), Commercial (up to 5.0)
- Delhi: Typically ranges between 1.2 and 3.6
- Bengaluru: Generally between 2.4 to 4.0
- Chennai: Usually around 1.5 to 2.0
- Kolkata: Commonly between 1.5 to 2.5
- Hyderabad: Unlimited, often between 6 to 13 in growth corridors
Hyderabad vs. Bengaluru: A Detailed Comparative Study
Housing Affordability Analysis
Higher FSI directly impacts housing affordability:
- Central Hyderabad property averages around ₹10,600/sq.ft, approximately 36% lower than Bengaluru’s ₹16,500/sq.ft.
- Rental costs for a centrally located 1-bedroom apartment are around ₹18,000 in Hyderabad, compared to ₹26,500 in Bengaluru, nearly 28% cheaper.
Commute and Infrastructure Efficiency
- Bengaluru residents spend approximately 132 hours annually stuck in traffic (average speed: 18.7 km/h).
- Hyderabad residents benefit from shorter commutes, losing only around 82 hours annually (average speed: 21.2 km/h), due to the city’s denser, vertically developed neighborhoods close to job hubs and superior infrastructure planning.
Economic and Real Estate Investment Trends
- Hyderabad secured nearly $6 billion in real estate investments between 2018-2023, surpassing Bengaluru and Mumbai.
- Hyderabad’s IT exports surged to $20 billion annually by 2023, driven by densely clustered vertical commercial developments.
- The city absorbed approximately 6.5 million sq ft of office space in 2023, the second-highest after Bengaluru.
- Hyderabad’s Gross Metropolitan Product (GMP) reached $75 billion by 2023, showing robust economic growth and productivity advantages over cities constrained by lower FSI.
Addressing Concerns: Common Arguments Against High FSI and Counter-arguments
- Infrastructure Strain
Argument: High-density construction places additional stress on existing infrastructure.
Counter-argument: Vertical growth reduces infrastructure costs significantly (up to 30%) by optimizing existing infrastructure usage. Proper planning ensures infrastructure improvements are implemented concurrently with vertical expansion, resulting in sustainable growth. - Environmental Concerns
Argument: Higher FSI could lead to loss of green spaces and increased pollution.
Counter-argument: Vertical development minimizes urban sprawl, preserving peripheral green spaces. Moreover, compact urban design encourages public transit and walking, significantly reducing emissions and overall environmental impact. - Increased Congestion
Argument: Higher densities may exacerbate traffic congestion.
Counter-argument: Denser, well-planned cities promote shorter commutes and make efficient public transport systems economically viable. Global examples (New York, Tokyo, Singapore) show high-density cities have far superior public transit usage, greatly reducing congestion. - Liveability and Quality of Life
Argument: High-rise living negatively impacts liveability due to perceived overcrowding.
Counter-argument: Properly planned vertical developments incorporate mixed-use spaces, amenities, and ample green areas, enhancing rather than diminishing urban liveability. Residents in high-density, mixed-use neighborhoods often report higher satisfaction due to increased accessibility and convenience.
A Real-Life Scenario: Raj’s Experiences in Bengaluru vs Hyderabad
Raj’s Daily Struggle in Bengaluru
Raj, an IT professional, resides in Bengaluru’s outskirts due to prohibitive central city rents. His daily 20 km commute to Electronic City takes 2-3 exhausting hours in relentless traffic. He pays around ₹25,000 monthly for a small 1-bedroom apartment, consuming a significant part of his income and causing severe stress. This lifestyle negatively impacts his productivity, mental health, and family life.
Raj’s Improved Life in Hyderabad
After relocating to Hyderabad, Raj now comfortably lives near HITEC City, renting a spacious high-rise apartment for just ₹18,000 per month. His daily commute is reduced dramatically to about 20 minutes each way. This newfound convenience significantly boosts his productivity, personal wellbeing, social life, and overall quality of life. Hyderabad’s vertical development ensures efficient infrastructure usage, affordable housing, and improved accessibility.
Global Benchmarks: Success Stories of High FSI
Several global cities highlight the success achievable through higher FSI:
- New York City: Manhattan’s high FSI (>10) has fostered dense commercial hubs, efficient public transportation, and immense global economic significance.
- Tokyo: Since adopting unlimited FSI policies in the 1960s, Tokyo tripled its housing supply, maintaining affordability despite massive urban growth.
- Singapore: With FSIs ranging from 8 to 25, Singapore achieved 88% homeownership rates, coupled with exceptional public transit and high livability standards.
- Hong Kong: Exceptionally high FSIs (~12+) have supported one of the world’s most efficient public transit systems, achieving over 90% transit usage and high urban mobility despite limited geographical area.

- Bengaluru’s notorious traffic congestion costs around ₹20,000 crore annually in lost productivity and wasted fuel.
- Urban sprawl contributes significantly to pollution, environmental degradation, increased commute times, and poorer quality of life.
Advantages of Vertical Urban Growth:
- Reduces infrastructure expenditure significantly (20-30%), optimizing existing investments.
- Increases economic productivity due to reduced commute times and proximity to workplaces.
- Promotes sustainable living by enhancing public transport efficiency, reducing pollution, and conserving green spaces.
- Boosts housing availability and affordability, stabilizing real estate markets and ensuring equitable urban growth.
Conclusion: Embracing Vertical Growth for a Sustainable Future
Hyderabad provides a compelling case for the adoption of higher or unlimited FSI policies. It demonstrates tangible benefits in affordability, livability, infrastructure efficiency, and economic productivity. Indian cities must urgently reconsider restrictive FSI policies to achieve sustainable urban futures.
