You should live in Plots/Buildings with square or rectangular shapes. Because Round, triangular, polygonal, and other odd shapes may constantly lead one into some of the other problems.
Do not block the North-East (Ishan) portion of the house/industry as it restricts the inflow of the blessings of God. It leads to tension and misunderstanding among the inhabitants.
Do not place the toilet/fireplace in the northeast corner of the house or industry as it may result in financial loss as well as mental tension and quarrel amongst people.
Never make three or more doorways in a straight line.

A properly placed round mirror and cordial paintings etc. in the bedroom can enhance your relationship. A wall poster having mountains/ snow-clad peaks of the Himalayas/Alps etc. on South- West wall can increase your strength and stability in life.
Important Vastu Tips
Well, a Boring, Underground water body or source should be in the north, east, or north-east of the plot.

An extension in the south-east may lead to a fire, accidents, theft, and court litigation. A south-west gate may keep the owner away from that place.
Keep all fire electrical equipment/gadgets like transformers, generators, motors, boilers, oil engines etc. in the south-east or southern portion of the Plot/Building
