You have a specific requirement for which you should be consulting a designer for proper planning and a vastu expert (If Required).
The total area is 18x70=1260 sq.ft.
I have attached an example of the layout drawing.
As u say you have a specific requirement so you can send the details of your site on support@gharexpert.com. Then we will send the layout according your requirements .
