Hi Rajesh, Construction cost varies on basis of site location, layout plan, number of a slab, on basis of what kind of materials you'll be using. -Thanks, -Neelam -Lines and Profile

Rahul, There is no upper or lower limit for design costs- it is based on individual taste, requirements and status. For example it may start with 4 lakhs and may run upto in crores.
