According to vastu (Not Jyotish etc) East and North facing plots are appropriate for house construction. Care should be taken while designing the house facing West and South direction because some directions have positive impacts while the other have negative on occupants of the house. For example if the kitchen is in South-East, there are always good results on health. But if the kitchen is in North-East, the health is affected adversely.
