BMC has stopped construction of a proposed 'landmark' building in Worli because of security concerns raised by the Navy. The Navy said that the plush 47-storey residential high-rise at Sasmira Marg would be a threat to vital defense installation INS Trata. Saumya Buildcon began work on the plot under section 33(7) of the development control rules after getting a No Objection Certificate from the fire brigade and BMC's building proposal allotment. As per the plans submitted by the project’s architect to the fire brigade, the 205.35 meter structure will have nine podium parking floors and 37 residential duplex flats. The structure has been built up to the plinth level. The Western Naval Command objected to the development and approached the state urban development department in June this year. It was decided in the meeting that any development within 300 meters of the defense installation would require a mandatory NoC from the Navy. The meeting was chaired by the department’s principal secretary, Mr. T Benjamin. After residents complained that Mr. Benjamin’s directives were not being implemented, the building proposal department issued a stop-work notice this week.
