Mumbai’s real estate map is being redrawn again and this time, it’s happening through an official government-to-consultancy agreement rather than just speculation or news chatter.
On August 7, 2026, the Mumbai Metropolitan Region Development Authority (MMRDA) signed a formal agreement with Singapore-based Surbana Jurong Infrastructure Pte. Ltd. to design the master plan for what’s being called “Mumbai 3.0” a proposed greenfield city spread across 323.44 square kilometers and 124 villages in the Panvel, Uran, and Pen talukas of Raigad district. The plan is due within 30 weeks and will define land use, mobility, and core infrastructure for what state officials are positioning as the region’s next major growth center.
What Exactly Is Mumbai 3.0?
Mumbai 3.0 is a planned greenfield city meaning a new urban settlement designed largely from scratch on relatively undeveloped land, rather than redevelopment layered onto an existing city. A few key facts worth knowing:
- Scale: Approximately 323.44 square kilometres, spanning 124 villages.
- Location: Spread across three talukas of Raigad district Panvel, Uran, and Pen.
- Origin: First notified by the Maharashtra government under the Maharashtra Regional and Town Planning (MRTP) Act in October 2024.
- Authority: MMRDA was appointed as the New Town Development Authority, meaning it holds direct responsibility for planning and executing the project.
- Status until now: For close to two years, the project existed largely as a notified boundary and a stated ambition, without a formal master-planning process underway.
What changed with the August 2026 agreement is that Mumbai 3.0 moved from “notified on paper” to “actively being designed” with a named consultancy, a defined timeline, and a clear deliverable.
Why Surbana Jurong’s Involvement Is a Meaningful Signal
This is the detail that separates a genuine planning milestone from a routine government press release, and it’s worth understanding in some depth.
Who Surbana Jurong is:
- The firm’s institutional lineage traces back to the organisations behind Singapore’s own transformation into one of the most methodically planned cities in the world.
- In India, the same firm has already been engaged for master planning Andhra Pradesh’s capital city, Amaravati.
- More recently, it has also been brought on to draft the detailed design for Bharat Future City, a large-scale planned urban development near Hyderabad.
What the agreement actually covers:
- Surbana Jurong will prepare Mumbai 3.0’s Vision Document, Master Plan, and wider planning framework.
- The stated timeline for this deliverable is 30 weeks from the signing date.
- The scope includes land-use planning, mobility and transport planning, and core infrastructure design.
Who was involved in signing it:
- MMRDA Metropolitan Commissioner Dr Sanjay Mukherjee signed on behalf of the authority.
- Surbana Jurong’s South Asia Chief Executive, Avinash Mishra, signed for the consultancy.
- Maharashtra Chief Minister Devendra Fadnavis was present at the signing.
- This agreement follows an earlier cooperation understanding the two sides had reached at the World Economic Forum in Davos in January 2026.
The policy angle worth noting: Commissioner Mukherjee described the effort as built around what he called an “innovative and people-centric land policy” designed, for the first time, to combine land-based benefits with monetary compensation so that landowners become genuine stakeholders in the development rather than simply displaced parties. CM Fadnavis, at the same event, pointed to NITI Aayog’s assessment that the Mumbai Metropolitan Region has the potential to grow into a $1.5 trillion economy, underlining how central this region is expected to be to the state’s broader growth strategy.
Does This Affect Karjat? Here’s the Honest Boundary
We want to be precise here rather than promotional, because overstating this would do you a disservice — and because buyers researching this topic deserve an answer they can actually rely on.
What’s confirmed:
- Mumbai 3.0’s notified boundary currently covers Panvel, Uran, and Pen talukas only.
- Karjat is not included in this boundary.
- No rezoning, land-use change, or master-plan decision under Mumbai 3.0 directly governs land in Karjat.
What’s genuinely relevant, even so:
- Pen Taluka, one of the three areas under Mumbai 3.0, sits in reasonable proximity to the Roha belt, where our Evernest Prime community is located.
- Large-scale, internationally backed planning commitments in a district typically bring wider ripple effects over time stronger infrastructure funding, greater institutional attention, and improved investor sentiment across neighbouring talukas, even those sitting outside the notified boundary.
- This kind of regional momentum has historically preceded (not immediately caused) improved connectivity and investment interest in adjoining areas.
The distinction that matters most: This is a regional-momentum story for Raigad district as a whole, not a Karjat-specific rezoning story. Both are useful to know. They simply mean different things for how you should weigh this news in your decision-making.
What This Means If You’re Evaluating a Second Home or Villa Investment Now
For buyers evaluating Karjat specifically where our Goodlife Estates and Trulife communities are located Mumbai 3.0 reinforces a trend that’s already been building rather than introducing a brand-new one. Consider this in context alongside what’s already confirmed and underway in the region:
- The Panvel-Karjat suburban rail corridor, which is already well advanced in construction.
- Ongoing road-widening and highway-upgrade projects connecting Karjat to Kalyan, Panvel, and the wider Mumbai Metropolitan Region.
- MMRDA’s recent appointment as Special Planning Authority for Karjat, Neral, and neighbouring areas, giving the region a more structured, long-term planning framework.
- Now, this renewed state-level and international planning focus on the broader Raigad growth belt through Mumbai 3.0.
Goodlife Estates in Karjat and Trulife, our resort-inspired gated villa community in Kashele, both sit within this wider connectivity and planning story. Neither community falls inside the Mumbai 3.0 boundary, but both stand to benefit from the same institutional momentum that’s steadily drawing infrastructure investment and buyer confidence into the region.
For Evernest Prime, near Roha, the connection is more direct. Pen taluka’s inclusion in Mumbai 3.0 places a formally planned greenfield city within reasonable proximity a development worth watching closely as Surbana Jurong’s master plan takes shape over the coming months.
Our Perspective, as a Developer Who’s Watched This Region for a Decade
We’ve been building nature-centric villa communities in this belt since 2015, under the guidance of a founder with 27 years of urban planning and real estate advisory experience across firms including JLL and Colliers. That vantage point has taught us a consistent lesson about how these announcements actually play out:
- Stage one is sentiment — news coverage, investor interest, and speculative discussion (where Mumbai 3.0 currently sits).
- Stage two is planning and land pricing — master plans get finalised, land-use maps are published, and early land transactions start reflecting the news.
- Stage three is actual construction and delivered infrastructure — the stage that genuinely moves property values in a sustained way.
These stages typically play out over years, not months. Mumbai 3.0 is currently in stage one. The next 30 weeks, as Surbana Jurong’s master plan document takes shape, will tell us considerably more about how far this ripple effect genuinely extends into Karjat and Roha — and we’ll continue tracking it and updating this article as concrete details, including land-use maps, connectivity plans, and phase-wise rollout, become public.
Frequently Asked Questions
What is Mumbai 3.0?
Mumbai 3.0 is a planned greenfield city covering approximately 323.44 sq km across 124 villages in the Panvel, Uran, and Pen talukas of Raigad district. It was notified by the Maharashtra government in October 2024, with MMRDA appointed as the New Town Development Authority responsible for its development.
Who is preparing the master plan for Mumbai 3.0?
Singapore-based Surbana Jurong Infrastructure Pte. Ltd. has been appointed by MMRDA to prepare the Vision Document and Master Plan for Mumbai 3.0. The firm’s institutional roots trace back to Singapore’s own urban development history, and it has previously worked on master plans for Andhra Pradesh’s capital Amaravati and Telangana’s Bharat Future City.
How long will the Mumbai 3.0 master plan take to complete?
Under the agreement signed on August 7, 2026, Surbana Jurong is expected to prepare the vision document, land-use plan, and mobility and infrastructure framework within a 30-week timeline.
Does Mumbai 3.0 include Karjat?
No. Mumbai 3.0’s notified boundary currently covers Panvel, Uran, and Pen talukas only it does not include Karjat. Karjat sits within the same broader Raigad district growth corridor, though, and benefits from related regional infrastructure momentum such as the Panvel-Karjat rail line, ongoing road development, and MMRDA’s Special Planning Authority role in the area.
Will Mumbai 3.0 affect property prices in Karjat or Roha?
There’s no direct rezoning impact on Karjat or Roha from Mumbai 3.0 itself. Large-scale, internationally backed planning commitments in a district typically increase overall investor confidence and infrastructure funding in neighbouring areas over time a trend worth monitoring rather than an immediate price driver.
Is now a good time to invest in a second home near Karjat or Roha?
That depends on your investment horizon, budget, and purpose — personal use, rental income, or long-term appreciation. Buyers evaluating this decision should weigh concrete, already-in-progress factors like the Panvel-Karjat rail corridor’s completion status, rather than speculative projects still in the planning stage, and should always verify a project’s RERA registration and site details directly.
Which Holistic Group projects are closest to the Mumbai 3.0 region?
Evernest Prime, near Roha, is the closest to the Mumbai 3.0 planning area given Pen taluka’s proximity to the Roha belt. Goodlife Estates and Trulife, both in Karjat, sit further from the notified Mumbai 3.0 boundary but within the same broader Raigad-district growth corridor.
