The builder is entitled to put such clauses even if they tend to restrict or take away from the entitlements under the government law
The plot is being sold to you subject to these conditions
So if document is registered in your name and if you breach the height and dwelling unit number restrictions, then builder can legally file a suit against you for specific performance of contract
Such conditions are put so that the structures coming on the entire land of the project are uniform and not haphazard
The above is a restrictive view considering contract and is not binding on buyer
if the plot is being sold to you on ownership basis, then i dont quite see how the builder can place such restrictions.
The above clauses would have been applicable and binding, had the contract been that of a lease of land
In case of ownership land, the owner buyer can do whatever he wishes with his plot so long as he complies with the local body building regulations for making constructions on the land
So in my view such clauses are voidable at instance of buyer as they tend to take away or reduce the bundle of rights sought to be sold on ownership basis
There is a difference between lease and ownership
The builder's stipulations seem more like that contained in a lease and not ownership document
