A major urban development initiative is taking shape in the Mumbai Metropolitan Region with the development of Third Mumbai, officially known as KSC New Town. The planned new city covers 323.44 sq. km and 124 villages across the Panvel, Uran and Pen talukas of Raigad district.
The Maharashtra Government notified the area on October 15, 2024, and appointed MMRDA as the New Town Development Authority (NTDA) for the region.
What Is Third Mumbai?
Third Mumbai, officially referred to as K. S. C. New Town, is being planned as a major new urban development area within the Mumbai Metropolitan Region.
The planning is aimed at addressing future population growth, employment requirements, transportation needs, housing demand, industrial development, logistics and modern civic infrastructure.
According to MMRDA, KSC New Town is envisioned as a modern, sustainable and people-centric city, with planning aimed at creating well-organised urban infrastructure.
323.44 Sq. Km and 124 Villages
The notified Third Mumbai/KSC New Town area covers 323.44 sq. km and includes villages located across:
- Panvel Taluka
- Uran Taluka
- Pen Taluka
The entire notified area has been brought under the KSC New Town planning framework.
Strategic Location Near Atal Setu, NMIA and JNPT
One of the biggest advantages of Third Mumbai is its strategic location within the wider Mumbai Metropolitan Region.
The area has connectivity and proximity to major infrastructure such as Atal Setu, Navi Mumbai International Airport (NMIA) and Jawaharlal Nehru Port (JNPT).
This strategic location could support the development of:
- Logistics hubs
- Warehousing centres
- Industrial zones
- Commercial centres
- Residential townships
- Transport hubs
- Employment centres
MMRDA has identified opportunities for industrial development, transport hubs, logistics parks and residential development within the KSC New Town planning area.
Singapore-Based Surbana Jurong to Prepare the Master Plan
The planning of Third Mumbai has entered an important stage with the involvement of international urban planning experts.
Singapore-based Surbana Jurong Infrastructure Pte. Ltd. has been appointed for preparing the Vision Document, Comprehensive Master Plan and related planning framework for KSC New Town.
The master planning process is expected to help determine the future direction of land use, infrastructure, transportation and urban development.
What Could Be Developed in Third Mumbai?
The planned city could eventually include several major development sectors.
Residential Development
Planned residential neighbourhoods and housing projects could be developed to accommodate future population growth.
Commercial Development
Business districts, offices, retail centres and service-sector hubs could emerge as the city develops.
Industrial Development
Planned industrial areas could support manufacturing and other economic activities.
Logistics and Warehousing
The proximity to JNPT, the airport and major road infrastructure could make the region an important logistics and warehousing destination.
Transport Infrastructure
Future planning is expected to focus on improved roads, public transport and multimodal connectivity.
What Does Third Mumbai Mean for Landowners?
The announcement of Third Mumbai has increased interest among landowners and property investors across the KSC New Town region.
However, not every parcel of land in the notified area will automatically become residential or commercial land.
MMRDA is studying existing land use, roads, industries, environmental factors, geographical features and transportation networks as part of the planning process. The proposed land-use plan will subsequently require approval from the Maharashtra Government.
Therefore, anyone considering land investment should verify the survey number, land-use classification, road reservation, acquisition status, zoning, CRZ/environmental restrictions and title documents before purchasing property.
Land Acquisition and Land Pooling Policy
The Maharashtra Government has also moved forward with a land acquisition and land allocation framework for New Town Development Authority areas and MMRDA projects.
The framework provides different options for landowners. Under the land-pooling model, eligible landowners can receive 22.5% of developed land in return, subject to the applicable conditions and process.
This model could allow eligible landowners to participate in future development rather than relying only on conventional compensation.
How Could Third Mumbai Benefit the Mumbai Metropolitan Region?
Third Mumbai is not simply about creating another residential area. It is intended to support the planned expansion of the wider Mumbai Metropolitan Region.
The development could potentially:
- Reduce population and traffic pressure on Mumbai
- Create new employment centres
- Support industrial and logistics growth
- Strengthen economic activity across the Navi Mumbai–Raigad belt
- Create new housing opportunities
- Bring modern infrastructure to developing areas
Is the Third Mumbai Master Plan Final?
No.
This is an important point for property buyers and investors.
The 323.44 sq. km area and 124 villages have been officially notified, but detailed planning proposals and the final land-use plan are still part of the planning process.
According to MMRDA, the proposed land-use plan will be prepared after studying the area’s existing conditions and will be submitted to the Maharashtra Government for approval.
Therefore, property investment decisions should be based on official planning documents rather than unverified claims circulating on social media or from property brokers.
Conclusion
Third Mumbai, officially known as KSC New Town, could become one of the Mumbai Metropolitan Region’s major future urban development corridors.
Its 323.44 sq. km area, 124 villages and strategic proximity to Atal Setu, Navi Mumbai International Airport and JNPT give the region significant long-term potential for urban, commercial, industrial and logistics development.
However, development will take place in phases. An undeveloped location today should not automatically be assumed to become a prime location tomorrow. The final master plan, land-use designations and infrastructure alignments will be crucial in determining which areas benefit the most.
Third Mumbai should therefore be viewed not simply as an immediate property boom, but as a long-term planned urban growth corridor with significant future potential.
