The BMC has written to the Kalachowki police asking that they investigate several unauthorised construction projects that have taken root at Lodha Aria, a high-rise apartment complex in Sewri. The request follows a notice issued by the city corporation to the housing society that’s responsible for the daily upkeep of the building and its administrative affairs, ordering the demolition of these illegal structures, which include a movie theatre, a party hall, a library, an office space and a toilet.The society was granted a month’s time, beginning September 9, to bring down these structures, but officials at the BMC say they failed to comply.According to the BMC’s letter to the Kalachowkie police, the grace period of a month granted to the society for regularisation ended on October 4, following which a civic engineer inspected the premises, and found that the structures had not been demolished, an offence punishable under sub section (7) of section 53 of the Maharashtra Regional Town Planning Act.This is not the first time the civic body has served the building notices regarding unauthorised construction. In November last year, two flat owners were served notices under section 53 (1) of the act ordering the regularisation of their flats which had been amalgamated by removing the partition wall without the BMC’s permission. It also stated that a bedroom in one of the flats had been illegally converted into a kitchen, while a toilet had been converted into a pantry. As is operating procedure, the BMC seeks police assistance in the drawing up of a panchnama, following which the city corporation may demolish the structures.Dilip Ugale, senior inspector of Kalachowkie police, said, “We will provide assistance to the BMC in our capacity when needed.” When Mumbai Mirrorcontacted Caroline Ghosh, chairperson of the Lodha Aria Cooperative Housing Society, she said she did not wish to comment on the matter.An official from the building and factories department of BMC’s F-South ward confirmed that they had written to the police. “Once the panchnama is done, we will demolish the unauthorised construction,” said the official, requesting that his name be withheld.
