Municipal Corporation Of Kolkata — Old building in risk due to lack of maintenance

Address:

Garfa 4th Lane Kolkata 75

My self Subhradeep Sen resident of the premises at Garfa 4th lane Kolkata 75 feel risk all the time as this building is very old now and has completed its life.
Being constructed back in 1960 this load-bearing wall type building has not been maintained since last 15 years and hence is showing huge cracks everywhere.
Beyond repair we requested other inhabitants to go for a developement by demolishing the property but all showed excuses of getting reduced floor area and held up the process.
The mumpty room and overhead tank is at most dangerous situation as it may fall down over the adjoining road causing damage to passer-by.
Please look into the matter and help
