The Mumbai police have filed an extortion complaint against two Goa residents and their accomplices, alleging that they seized Rs 41 lakh and demanded Rs 6 crore from a real estate company’s agent in order to continue work on an ongoing project in the coastal state, an official said on Sunday.

The NM Joshi Marg police submitted a FIR on August 27 in response to a complaint from a liaison officer with ‘The House of Abhinandan Lodha’, who claimed that the accused threatened to halt building at the project site until payment was made, according to the official.

According to police, the accused, Siddhesh Jana Tari, Pritesh Salgaonkar, and their associates, allegedly sought Rs 6 crore from the complainant to allow the company’s Goa project to go without interruption. Tari reportedly accepted Rs 34 lakh, while Salgaonkar accepted Rs 7 lakh from the complainant in numerous instalments over the last five months, totaling Rs 41 lakh, they claimed.

However, the accused allegedly wanted Rs 10 lakh recently, and the complainant, sick up with the incessant threats and demands, approached the NM Joshi Marg police station, which has jurisdiction over the company’s office, according to the official. The police have filed a case under relevant parts of the Bharatiya Nyaya Sanhita (BNS), including provisions for extortion and criminal intimidation, and an investigation is continuing.

Mumbai’s redevelopment market has received another significant transaction, this time in Chembur.

Mahindra Lifespaces has entered into a development agreement for the redevelopment of Twinkle Star Co-operative Housing Society in Chembur. The agreement is valued at approximately ₹142.72 crore and was registered on August 17, 2026, according to property-registration data reported in connection with the transaction.

The deal is important not just because of its headline value.

It provides another example of how established Mumbai neighbourhoods are becoming increasingly important redevelopment markets.

What Is the Chembur Project?

The project involves approximately 11,241.7 square metres of land spread across seven plots in the Borla/Chembur area along Ghatla Village Road.

The redevelopment involves nine existing buildings and 133 existing members.

The agreement value is reported at ₹142.72 crore.

Property documents reported in connection with the transaction indicate that stamp duty of approximately ₹7.23 crore was paid.

The project demonstrates the scale at which redevelopment is now taking place in Mumbai.

Why Chembur?

Chembur has several characteristics that make it attractive to residential developers.

The locality is established.

It has access to major road networks.

It is connected to central and eastern parts of Mumbai.

It also benefits from proximity to important employment and commercial areas.

Infrastructure improvements are adding another dimension to the location.

The wider Chembur-Kurla-Sion belt is increasingly integrated into Mumbai’s evolving transport network.

That combination of established neighbourhood infrastructure and redevelopment potential makes Chembur an important micro-market.

Why Is a ₹142 Crore Agreement Significant?

A transaction of this size illustrates the commercial value developers can see in established housing societies.

For developers, redevelopment is not simply about constructing a new building.

The developer must evaluate:

• Land area
• Existing members
• Rehabilitation requirements
• Development potential
• Construction costs
• Sales potential
• Financing
• Approvals
• Market demand

The project only works if the economics make sense after considering all these factors.

Therefore, a ₹142.72 crore agreement reflects the commercial scale of the opportunity.

What Does It Mean for Existing Society Members?

For existing residents, redevelopment can potentially deliver a completely new residential environment.

Depending on the final project and agreement, members may receive new homes with modern layouts and amenities.

But the headline agreement value does not tell residents exactly how much they will receive.

The most important document for members remains the legally executed redevelopment agreement and associated documents.

Residents should carefully understand:

• New carpet area
• Corpus
• Transit rent
• Shifting expenses
• Possession timeline
• Delay compensation
• Parking
• Amenities
• Construction specifications
• Security arrangements

Why Redevelopment Deals Matter to Other Mumbai Societies

Every major redevelopment transaction can serve as a market indicator.

When established developers enter society redevelopment projects, other societies may become more aware of their own development potential.

A society that has remained unchanged for decades may begin asking:

What is our land actually worth?

That question can fundamentally change redevelopment negotiations.

However, societies should not simply compare their land with another project’s headline value.

Every property has different development rights, plot configuration, reservations, FSI/TDR conditions, existing member requirements and market conditions.

Redevelopment Is Not Just About Land Value

A common misconception is that a society can simply estimate the value of its land and demand a percentage from the developer.

The economics are more complicated.

The developer may have to bear:

• Construction costs
• Rehabilitation costs
• Rent
• Financing costs
• Approval costs
• Premiums
• Marketing expenses
• Taxes
• Infrastructure costs
• Sales and administrative expenses

The final commercial offer therefore depends on the project’s overall feasibility.

Chembur’s Infrastructure Advantage

Infrastructure can play an important role in redevelopment economics.

MMRDA has been expanding the region’s transport network, including road and metro connectivity.

The SCLR Phase-II project was inaugurated in August 2026, while the Chembur section of Metro Line 2B also became operational in August. MMRDA lists the operational phases and project status on its official website.

Better connectivity can make established neighbourhoods even more attractive to residents and developers.

Does This Mean Chembur Property Prices Will Rise?

Not automatically.

Infrastructure and redevelopment can support demand, but property prices depend on several factors.

These include:

• Supply
• Demand
• Interest rates
• Project quality
• Location
• Connectivity
• Economic conditions
• New launches
• Rental demand

A redevelopment project may improve the value of a specific building without causing a uniform increase across the entire locality.

Homebuyers should therefore evaluate individual projects rather than assuming that every Chembur property will benefit equally.

What Developers Can Learn

The Chembur transaction also demonstrates the importance of strategic land acquisition.

In a mature city such as Mumbai, developers increasingly have to look beyond traditional vacant-land purchases.

Society redevelopment offers another route to expand residential portfolios.

The ability to negotiate with residents, structure financing and execute complex redevelopment projects is therefore becoming an increasingly important development capability.

What Societies Can Learn

The transaction also offers lessons for societies.

First, understand the commercial potential of the property.

Second, obtain multiple proposals.

Third, do not evaluate developers only on the basis of additional carpet area.

Fourth, examine the developer’s financial capacity and previous redevelopment projects.

Finally, make sure the final agreement protects residents against delays and other project risks.

Chembur’s Bigger Real Estate Story

Chembur is not an isolated redevelopment story.

Across Mumbai, ageing societies are increasingly becoming redevelopment opportunities.

The pattern is logical.

Established neighbourhoods have strong existing infrastructure and demand, while new land is difficult to find.

Redevelopment allows developers to introduce new housing supply without moving to distant peripheral markets.

For residents, it can mean the transformation of ageing buildings into modern homes.

For developers, it can unlock valuable development opportunities.

Bottom Line

The ₹142.72 crore Chembur redevelopment agreement is significant because it demonstrates the scale of Mumbai’s redevelopment economy.

The project involves nine existing buildings and 133 members on approximately 11,241.7 square metres of land.

For Chembur, it reinforces the locality’s importance as an established redevelopment market.

For Mumbai’s wider housing market, it is another example of how redevelopment is becoming one of the city’s most important sources of new residential development.

The Brihanmumbai Municipal Corporation (BMC) has begun demolition action at Rustomjee Crown, the luxury residential development in Prabhadevi, Mumbai, over alleged unauthorised alterations and changes involving common areas. The initial action reportedly targeted structures in three to four flats, while a much larger number of apartments in Wings A and B are under scrutiny.

Reports indicate that the civic body has issued notices to a large number of flat owners following complaints regarding alleged construction, additions, alterations, amalgamation of flats and occupation or enclosure of spaces that were not included in the approved plans or FSI calculations.

The development has attracted attention because Rustomjee Crown is one of Mumbai’s prominent luxury residential projects, with apartments reportedly owned or occupied by several high-profile individuals.

Why Are 128 Flats Under Scrutiny?

The dispute primarily relates to alleged alterations involving common and service areas of the building.

According to reports, the areas under scrutiny include:

• Spaces around lift areas
• Kitchen ducts
• Ventilation shafts
• Other common areas
• Areas excluded from FSI calculations
• Alleged amalgamation or modification of individual flats
• Additions or alterations that may not correspond with sanctioned plans

The BMC’s action is focused on determining whether such spaces have been incorporated into individual apartments or modified without the necessary approvals.

While some reports have referred to 128 notices, others have reported 138 notices involving owners in Wings A and B. The exact number may therefore depend on the stage or scope of notices being considered.

What Has The BMC Said?

The civic body has maintained that it followed the prescribed legal procedure before taking action.

According to the reported proceedings, notices were issued to concerned occupants and other parties, providing an opportunity to respond to the allegations. A notice under Section 488 was also reportedly served on August 19 to owners, occupants, society office-bearers and the developer regarding an inspection scheduled for August 24.

The demolition action follows this process in cases where the civic authority considers the structures or alterations to be unauthorised.

The proceedings are expected to continue, and the final extent of demolition or other action will depend on the findings and applicable orders.

What Is The Rustomjee Group’s Response?

Rustomjee Group has disputed the allegation of any violation on the developer’s part.

The company has stated that the construction was undertaken according to plans sanctioned by the competent authorities and in compliance with applicable rules and regulations. It has also pointed to the project’s Occupation Certificate and said that it is cooperating with the authorities.

The developer has further stated that residents are being encouraged to undertake corrective measures wherever required.

This distinction is important because the reported allegations largely concern alterations associated with individual apartments and common areas. The BMC’s proceedings will establish responsibility in individual cases based on the relevant approvals, records and actual construction on site.

Rustomjee Crown: What We Know About The Project

Rustomjee Crown is located in Prabhadevi on the former Crown Mill compound and consists of three residential towers.

Wings A and B reportedly rise to 63 floors and have received Occupation Certificates, while the third wing is under construction. The overall development has around 720 apartments.

Its location, scale and premium positioning have made it one of the notable luxury housing developments in central Mumbai.

The controversy has therefore attracted considerable attention, particularly because of the project’s high property values and the potential financial implications for affected homeowners.

Are The Common Areas Worth ₹250 Crore?

Some media reports have estimated the value of the disputed common spaces at more than ₹250 crore.

However, this figure needs to be viewed carefully.

The reported valuation appears to be based on prevailing property prices and the estimated area involved rather than a formal valuation conducted by the BMC. Therefore, it should not be interpreted as an official civic assessment of the value of the allegedly encroached or altered areas.

The actual financial implications for individual homeowners would depend on the area involved, the nature of the alteration, applicable regulations and the final orders passed by the competent authority.

Why This Case Matters For Mumbai’s Luxury Housing Market

The Rustomjee Crown case highlights a larger issue facing Mumbai’s high-value residential developments: what happens when apartment owners modify their homes after possession.

Luxury apartments often involve complex layouts containing ducts, shafts, service areas, lift lobbies and other common spaces. While residents may consider certain areas as extensions of their homes, such spaces can have specific legal and planning classifications.

Any alteration that changes an approved layout or incorporates common or excluded areas can potentially trigger regulatory scrutiny.

The case therefore goes beyond one residential project. It could serve as an important reminder to apartment owners, housing societies and developers about the importance of obtaining the necessary permissions before carrying out structural or layout changes.

What Could Happen Next?

The BMC’s proceedings are expected to determine which alterations, if any, are unauthorised and what action is legally permissible in each case.

Possible outcomes could vary depending on the individual property and the nature of the alleged violation. These may include removal of unauthorised structures, corrective measures or further proceedings where required.

The owners and other concerned parties are also expected to have opportunities available under the applicable legal process to present their cases or challenge orders where appropriate.

Until the proceedings are concluded, allegations should not be treated as established violations against every flat or every resident named in the notices.

Key Takeaways

• BMC has started demolition action at Rustomjee Crown in Prabhadevi.
• Around 128–138 flats in Wings A and B have reportedly received notices or are under scrutiny.
• Allegations involve common areas, ducts, shafts, alterations and alleged deviations from approved plans.
• Rustomjee Group has denied violations on the developer’s part.
• The reported ₹250 crore valuation of disputed areas is not an official BMC valuation.
• The ongoing proceedings could have wider implications for Mumbai’s luxury residential sector.
• The final action will depend on the findings, applicable approvals and legal proceedings.

Conclusion

The BMC’s action at Rustomjee Crown puts the spotlight on how Mumbai regulates alterations in large residential developments after occupation. With a significant number of flats reportedly under scrutiny, the proceedings could become an important case study for developers, housing societies and luxury-home owners.

For now, the focus remains on establishing which alterations comply with sanctioned plans and which, if any, require removal or corrective action. The final outcome of the BMC proceedings will determine the extent of action at the Prabhadevi project.
