YM Infra Group (YM Infra), in association with Ashwin Sheth Group, has launched One Marina, a 74-storey residential tower at Marine Lines in South Mumbai. The development covers about one and a half mn sq. ft. and has an estimated gross development value of Rs 28 bn. It is intended to be the tallest residential building in its immediate micro market and to respond to premium demand amid limited large format launches in the area. The project is presented as offering lifelong unobstructed views. Residences will be available in two, three and four bedroom layouts, along with duplexes and penthouses, with ticket sizes from Rs 70 mn to Rs 450 mn. The low density design averages six residences per floor to emphasise exclusivity and efficient vertical circulation. About 95 per cent of apartments will face the Arabian Sea and the first habitable floor is set at 131 feet above sea level to preserve privacy and panoramic sea vistas. Amenities are located on the 69th and 70th floors. Architecture is by ARK by Reza Kabul Architects, with landscape design by Site Concepts International and structural and MEP consultancy by Mahimtura Consultants and PDA Associates respectively. Kvant Lasers has been engaged for architectural illumination. The fully glazed facade integrates high performance energy glass to improve thermal efficiency while maintaining views. The tower includes 722 parking spaces across eight podium levels and two basements to address infrastructure needs in South Mumbai's dense urban fabric. The launch formalises the strategic partnership between YM Infra and Ashwin Sheth Group, combining execution capability, brand equity and capital to pursue selective high impact launches in South Mumbai. YM Infra is positioned as a focused developer of supply constrained luxury micro markets through disciplined capital deployment and structured execution. Ashwin Sheth Group, established in nineteen eighty six, brings more than 80 landmark projects and has delivered over 40 mn sq. ft., underpinning long term value creation through the collaboration.
