Whew! So much to say, so little to go on. First...you need an architect. Hire one. Then you need an engineer. Hire one of them too. Hiring a contractor to consult on cost and practical issues is a good thing too. Once your team is assembled, listen...hard! Best of luck!

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

Can you please elaborate where the site is located and what are its surroundings? It will help understand the local by-laws which will finally govern the building footprint that will be available for your construction. Also please share your requirement. Thank you. Ar.
