7 billion people, each having 1000sq feet house requires 651 thousands square km or land which is 0.43% of earth surface not covered in water.

1. That's significantly less than the total urban land area that already exists.
2. We have multistory buildings.
Urban land include commercial & industrial urban land. So do, unless I am mistaken, urban roads and parkings.
1000 sq/ft per person is laughably huge. 1000 sq/ft/5person family is adequate.
