In South West area, you should have your master bedroom. If you plan to use 1st floor for master bedroom, have your master bedroom on SW side of 1st floor.
Kitchen should be in South east side, so your living area can move into the North East.
Centre part of your home should not be used for any structure.
In the mirror image of this plan, your Master bedroom and Living area would come at proper place. Even your dining area would be in NW direction, which is good. but Kitchen shouldn't be at that location. Second best place for kitchen is NW.
