Construction of room in cellar area in apartment

The builder has to provide you what ever you have agreed to purchase in terms of agreement to sell / purchase and not entire plot of 500 sq yds..

Respected sir, here the main legal point is, in stilt parking how the builder can raise structures and construct rooms ?

Builder can raise constructions as per approved map ( Municipal authority ) and if he is making constructions against by laws or approved map, you can get rstrained him by injunction order.

You can file injunction suit against the person who is constructing in the paking lot... then stay would be granted to you... and all the construction done by him in parking lot will be destroyed by concerned authorities... 

The builder cannot raise any structure including converting the cellar or stilt parking into room with bathroom facility.

It is a deviation of the approved plan

The construction of room can be demolished by the local civic body.

The builder/owner thinks that he is still the owner of the entire building and he forgot that once he sold the flats he is no more an owner.

You can give a complaint with the local comptetent civil authority which sanctioned the building plan approval
