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!

Can you provide some photos of the exterior?

Hello there, You need to consult with a local architect first for the layout and plan approval. They will provide you with floor plan and furniture layout, 3D elevations etc. Also, they would send them for approvals. What you're asking for is a paid professional service. Please consult locally first. Else, if you need anything specific, please feel free to connect with us. Also, your budget is too tight for 800 sqft unless it is an open plan. Cost of construction starts from 1100-2000/ sqft depending on materials and contractor. Usually that will cover design and approvals costing as well. Regards, Aurum Ideas and Spaces Bhubaneswar
