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.
