Dear Sir,
Our society had gone in tdr and have extended the building from 3 floors to 6 floors. After the completion of the building and after receiving the OC, most of the members have extended their house till the pillars except a couple of flats. Now these flats also wants to extend but the society have taken a conscious decision not to allow further extension. My query is as under:
1) is the extension legal, if not, where can I complain and how.
2) If it is legal, can the society stop the remaining member.
