The 4 level structure is attached to bldg no C
Means it is an exclusive part of bldg C
Which in turn means that only residents of bldg C can avail the parking spaces in that 4 level structure as determined by the society
The OC of bldg C also specifies the same
If certain residents from bldg A and B were sold parking slots in the structure attached to bldg C, that would not mean that they can lay a claim over the parking slots in bldg C
The flat purchasers in A and B would be shown the building plans as regards bldg A and B. So they had full knowledge that the structure attached to bldg C is not any annexure to bldg A and B
The fact that 3 separate societies are formed shows that the flat purchasers in each bldg were aware what is part of their bldg and what is not
At the highest the A and B bldg residents have a claim against the builder who sold the parking slots in bldg C to them. Those purchasers purchased the bldg C parking slots at their own risk and peril
Those sales would not bind the proposed society to be formed of bldg C residents
