Dear Sir, I live in apartment in GF flat. My flat consists of 4 floors and 33 Flats, where car park is in the basement. The flat is handed over in 2006 and at the time of handover, builder constructed In front of my flat there is a small(12 feet by 22 feet) Indoor Garden. Over a period of no plants was growing in the garden and no more new plants Planted. Meanwhile the walkways tiles where getting dirty tiles specialist suggested removing the sand from the garden, so association decided to remove the sand and tile it. And the area is tiled now. Once the area is tiled slowly children started to play in the last four months, Now it become regular that around 20 kids play in that area and noise level is so high that i Could not able to live in apartment picefuly, being work from home our employers are complaining that we could not have meeting. I have complaint to association but no use. What is my legal rights to live in piece, what kind of legal action I can initiate. Thanks & regards Venkat
