A badminton coach inquired about leasing an abandoned open ground in a housing society to build a complex. The society bylaws state 20% of the area must remain open for playing. Experts clarified that while the space is designated for playing, construction, even temporary, is generally not permitted on society land without violating bylaws and the sanctioned plan. The society cannot lease its land to private individuals for construction, and outsiders cannot claim rights to use the space.
