NEW DELHI: The prime minister's new residential complex will have 10 four-storey buildings with a maximum height of 12 metres, according to the government's latest proposal for the redevelopment of Central Vista. Official sources said that there is "no question of dropping" the proposed new Prime Minister's Office (PMO) from the Central Vista Redevelopment project, after the CPWD did not mention the same in its new proposal before an expert panel of the Ministry of Environment and Forest. The Central Public Works Department (CPWD), which is executing the project, has revised the estimated cost from Rs 11,794 crore to Rs 13,450 crore. The prime minister's new residence will be built on a 15-acre plot and it will have 10 buildings and they will have ground plus three floors, the CPWD said in its proposal.
