For condo, u can't hack or change the design, but if such prob exists, then use the 明堂 method to dissolve the bad chi or sha. If u go to a rich man's hse, he aways hv a space before the main door and after the main door. When bad turbulence comes to the hse, let is dissipate before the door, and if it enters the door, let it dissipate further before it enters the main living to hit the family. The last thing is to let it enter the rooms which is restful and shld be yin.

If u draw  an X across hse plan, that is the heart of the hse where the main activity will take place - if the center is in the kitchen, then the family will like to eat. If it is the living room, the family will spend time there. If the X is outside the hse, then the family is seldom at home. Test this out and prove me wrong on this...
