The Delhi Master Plan 2047 aims to increase housing supply and reshape transport and land use. It focuses on higher-density development through transit-oriented development around public transport corridors to improve access to mass transit and optimise land use. The authority has identified about 207 sq km along Metro, Regional Rapid Transit System and railway corridors for higher-density development, with influence zones typically within 500 metres of stations. Authorities estimate these areas could accommodate about one point seven million (1.7 mn) dwelling units over the next ten years and allow high-rise development within 250 metres of Urban Extension Road II subject to rules. The plan proposes land pooling to unlock stalled plots and offer landowners a share of developed land, and a higher floor area ratio for slum rehabilitation to make redevelopment financially viable. A uniform redevelopment framework targets ageing two-storey DDA colonies built on individual plots, allowing built-up plots to receive redevelopment rights comparable with vacant residential plots subject to norms on floor area ratio, ground coverage, height and safety. The measure aims to increase housing capacity within existing neighbourhoods and reduce pressure for outward expansion. To accelerate construction approvals the plan amends the Unified Building Bye-Laws 2016 to remove prior no-objection certificates from several departments including the Delhi Pollution Control Committee, Delhi Jal Board, the Forest Department and the Chief Inspector of Factories. The change seeks to reduce procedural delays and speed project commencement. Land use changes include approval of 19.63 hectares in Narela for a Metro depot linked to the proposed Rithala-Kundli corridor, which is expected to improve connectivity between north-west Delhi, Rohini and Narela and adjoining areas of Haryana. The plan allows regulated commercial and institutional activity in 70 peripheral villages under a Green Development Area framework and proposes expansion of green areas across 174 villages. It also strengthens protection for the Yamuna floodplain by prohibiting concrete structures in the core O-Zone and limiting the remainder to recreational uses, while a proposed Waste-to-Energy plant in Gazipur forms part of wider waste management measures.
