Following a 2007 Memorandum of Understanding (MoU) with the Central Public Works Department, the Archaeological Survey of India and the South Delhi Municipal Corporation, the Aga Khan Trust for Culture (AKTC) commenced conservation and landscape works at Sunder Nursery. The Nursery would eventually become a 90-acre (36 hectare) city park with distinct heritage, ecological and nursery zones, as well as all the expected facilities.
