Its not about shape, its about build quality and design.Time to change the shape of houses to something that can take 200 mph winds.
My house for example is actually rated for 200mph winds. Each stud is attached at the bottom and top using a large Y-piece of steel reinforcement. Similar reinforcement on the roof, and each roof tile is hammered in by hand which helps achieve the 200mph rating. Polyfoam is also very strong. It really doesn't add much cost to the home, but those are simple corners that many builders simply cut because its not something you can see and most people don't care to pay a few grand extra to know their house can withstand high winds because... well... what are the chances, right?
Unfortunately, that doesn't mean you're protected from debris though, so if the neighbors car goes flying into your house... well, sucks to be you.
