I read about how for women, to have marriage luck, the southwest corner of the house should not be missing and should not be used as kitchen/bathroom. Not only that, the northwest corner, which represents a man in her life, should also not be missing, or used as kitchen/bahtroom. My unit is not a full square, instead the south-west corner belongs to another unit. I don't know if in this case, the south-west part can be considered as the southwest corner. Not only that, my north-west corner is actually a bathroom. Sigh! It is very difficult to get a unit with all corners right and in all houses that I've occupied, these two marriage corners have always been a ktichen or bathroom.
These two marriage corners should be kept well-lit.
