I have not specifically looked for modern, but you can try houseplans.com and you can filter your search. Also try a google search for contemporary house plans. I am sure there are multiple sites out there.

hi i want a hall on ground floor and kitchen,sitout and one bathroom and i want stairs in hall and on first floor i want two master bedroom and on three side open area. i just have one plan

Why bathroom is in front of the house? Is there any specific reason? Why not put the kitchen in the place of bath and put the bath in the place of kitchen with a corridor to go to utility area?

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
