Answer 1

Round homes are structurally stronger and more energy efficient due to better heat circulation and less exterior surface area for heat to escape.

I think rectangular homes are simply easier to tetris together in the grid of big city streets.

If you want a strong house that can hold a lot of extra weight though, the best shape to go with is a hexagon. They have the advantage of round homes but they tessellate perfectly without wasted space. The honeycomb shape is prevalent in nature due to its efficiency in every way.
