Need information on digging borewell in a constructed house

I am in the process of constructing my house Bangalore (east facing road). Currently, the association of the layout provides borewell water (while there is no Kaveri water yet to this area). There is no permission to dig borewell in this layout. But in my plan, I want to make sure that there is a provision in the east side for digging a borewell in future whenever needed.

What should be done in this regard? How much open to sky space and height in the ground floor should be left? What are the procedures? What would be the specification (lxhxw) of the borewell vehicle that would be coming into portico for the borewell requirement?

Any suggestion is much appreciated.
