YM Infra, in strategic association with Ashwin Sheth Group, has launched One Marina, a 74-storey luxury residential tower in Marine Lines, South Mumbai. The development spans one point five million (1.5 mn) sq ft of total development area and carries an estimated gross development value of Rs 28 billion (28 bn). The project is set to be the tallest residential tower in its immediate micro-market and represents a significant addition to premium South Bombay housing supply. The tower will offer residences in two, three and four bedroom configurations together with duplexes and penthouses, featuring low-density layouts of approximately six residences per floor to emphasise exclusivity and privacy. Indicative ticket sizes range from Rs 70 mn to Rs 450 mn. The design ensures that ninety five per cent of apartments are oriented towards the Arabian Sea and locates the first habitable floor at 131 feet above sea level to unlock uninterrupted sea views, with luxury amenities occupying the 69th and 70th floors. Architectural and technical execution brings together ARK by Reza Kabul Architects for architecture and master planning, Site Concepts International for landscape design, Mahimtura Consultants as structural consultant, and PDA Associates for MEP consultancy, with Kvant Lasers engaged for architectural illumination. The fully glazed façade will integrate high performance energy glass to improve thermal efficiency while preserving panoramic views. The scheme provides 722 parking spaces distributed across eight podium levels and two basement levels, addressing a critical infrastructure requirement in the dense urban fabric. The launch formalises the strategic association between YM Infra and Ashwin Sheth Group, combining execution capability, brand equity and growth capital. YM Infra is presented as a focused platform with two point five mn sq ft under development, six active projects and 2,100 residences underway, concentrating on regulated redevelopment in supply constrained micro-markets. Ashwin Sheth Group brings over four decades of delivery experience, a portfolio exceeding 40 mn sq ft and more than 35,000 families housed, reinforcing the partnership’s capacity to deliver high-impact luxury development.
