Palais Royale is an under-construction supertall residential skyscraper in Worli, Mumbai, Maharashtra, India. At 320 metres (1,050 ft), it holds the distinction of being India’s tallest tower and features the world’s tallest atrium within a residential building. The building had topped-out in 2018 but the facades and interiors of the skyscraper are still under construction. The project has successfully resolved all legal matters and is now in its final stages of development, with possession anticipated by 2025. Developed by Honest Shelters Pvt Ltd and designed by Talati and Partners, India, with structural engineering by Sterling Engineering Consultancy Services Pvt. Ltd., India, and peer-reviewed by CBM Engineers, USA. The MEP (Mechanical, Electrical, and Plumbing) work is managed by Currie & Brown, London, UK . Reinforcement fabrication is handled by Ready Made Steel, while formwork solutions are provided by MEVA, Germany, in partnership with Pranav Constructions Limited, India. The principal contractor for the project is Shapoorji Pallonji Construction, ensuring high-quality execution of the construction. This collaboration brings together expertise from India and around the world to create a truly iconic project. The Project has received a second set of Occupation Certificate (OC) in December 2024. The Brihanmumbai Municipal Corporation (BMC) had issued the last OC to the property’s ground plus 27 floors, in August 2022. With the new approvals, a cumulative 53 floors have been cleared.

The building is being constructed on land previously owned by Shree Ram Mills Ltd. Permits for construction were granted in 2005, and construction began in 2008. The project's progress has been stalled due to multiple public interest litigation lawsuits filed by NGOs Janhit Manch and UHRF of Delhi. These litigations were disposed of by the Supreme Court of India in October 2019. In its judgement, the Court observed that the lawsuits lacked consistency and bona fides. The promoters of the project have contended the lawsuits are motivated and sponsored by private interests of rival builder Mufatraj Munot of Kalpataru Builders.

The design of Palais Royale is a harmonious blend of modern engineering and traditional principles. The tower features an octagonal structure that minimizes wind resistance while adhering to Vastu principles, ensuring both stability and auspiciousness. One of its standout features is the world’s tallest residential atrium, soaring to an incredible height of 212 meters (696 feet). Palais Royale is a pioneer in construction innovations. It is the first residential tower in India to use M80 grade concrete, which is typically used in nuclear power plants, ensuring unmatched strength and durability. The structure is also designed to meet rigorous global seismic standards, with braces and dampers strategically placed to enhance stability and minimize recovery time after seismic events. Extensive wind tunnel testing by RWDI has validated its stability under lateral loads, ensuring safety and comfort for residents. The construction employs advanced German MEVA formwork systems and luffing cranes to achieve precision and efficiency. The foundation of Palais Royale is another feat of engineering. A 3.5-meter-thick raft foundation, built on rock with a bearing capacity of 150 t/m², provides a solid base for the structure. The design incorporates a post-tensioned flat slab system for the parking and amenity levels and braces with dampers to reduce lateral movement during seismic events. These engineering advancements make Palais Royale a benchmark for structural integrity in high-rise buildings.

Palais Royale exemplifies environmental responsibility with its ground breaking sustainability measures. The project is designed to conserve up to 20 million litres of water annually, thanks to advanced rainwater harvesting and recycling systems. Greywater treatment facilities ensure that all water used, including that for swimming pools and faucets, meets potable standards. Air quality is another priority, with each apartment receiving treated fresh air through independent units that remove impurities and humidity, effectively making Palais Royale the "lungs of Worli." During construction, 75% of waste was recycled, showcasing exemplary waste management practices. The materials used are environmentally friendly and FSC-certified, ensuring responsible sourcing and reducing environmental impact. Palais Royale’s innovative sewage and garbage treatment systems further contribute to its green credentials. All organic waste generated is processed into manure through a vermicomposting system, ensuring zero landfill impact. By integrating these sustainable practices, Palais Royale not only offers luxury but also a commitment to ecological harmony.

The site was put up for auction in May 2019 but did not attract any buyers. Another auction was held in mid-2019, and the incomplete site was bought by a company named Honest Shelters for ₹ 705 crore. The construction of the Palais Royale project was restarted by Honest Shelters in 2020 and reached completion in 2024, with only the interiors and façade finishing remaining, which are scheduled for completion by 2025. The project spans a vast land parcel of 4.45 acres, with an impressive footprint of 53,000 square feet. The tower is a marvel of engineering and design, rising 72 storeys high. It features two basement levels, two lobby levels, seven car parking levels, seven floors dedicated to amenities, and 43 residential floors starting from the 21st floor, at a height of 270 feet. The residential offering includes 153 ultra-luxury apartments, ranging in size from 740 to 1,300 square metres (8,000 to 14,000 sq ft). Among these is the world’s largest penthouse, spanning an extraordinary 125,000 square feet across three floors, setting a global benchmark for luxury living. The Tower has extensive range of amenities spread across seven levels, totalling 200,000 square feet. Every aspect of the amenities has been thoughtfully designed to cater to the diverse needs of its residents. The recreational amenities are unparalleled, including a tennis court stadium with spectator seating, indoor and outdoor kids' play areas, a cricket pitch, a basketball court, and rock climbing zones. Three swimming pools cater to various preferences, from relaxation to vigorous exercise. Fitness enthusiasts can enjoy a state-of-the-art gymnasium designed with multiple training zones, offering stunning views to inspire workouts. Residents can indulge in a luxurious lifestyle with facilities like a banquet hall, gourmet restaurants, and a world-class spa. For entertainment, there is a private theatre, and serene zen gardens that provide a tranquil retreat amidst urban living.

Palais Royale is home to prominent business leaders and influential share market investors in India, such as Madhu Kela (MK Ventures), Anand Rathi (Anand Rathi Financial Services Limited), Vikas Khemani (Carnelian Asset Management & Advisors Pvt Ltd), Pranav Shah (Pranav securities pvt ltd). The most recent purchases, in December 2024, were made by the promoters of Metro Brand Ltd., who acquired five luxurious apartments within the prestigious Palais Royale project. According to documents accessed by IndexTap.com, the total value of these transactions was ₹405 crore. Now, construction as well as sales at Palais Royale have resumed from what was an upward of ₹20 crore back in 2007 to ₹27 crore in 2013 and now breaching the ₹100 crores mark, for a single Apartment.
