The front boundary walls of east and North facing houses needs to be erected then first construction of southern western compound walls should be completed.
The east and north compound wall height should be kept lower than south and west walls. The ideal situation of height, thickness and weight of compound walls is very important to take care according to the tenants as per Vastu shastra.
According to Vastu science the southern wall should be the highest and heaviest of all walls whereas western compound wall should be little lighter and lower than it. The northern must be further lighter and lower than the western wall. Finally the eastern wall should be the lightest and lowest of all walls. However northern and eastern walls can be kept equally thick, low and lighter. This approach shall help in increasing the positivity inside the construction site that may rather speed up the construction work.
“The Main door carries the highest value in a house as per Vastu”.
Yes it does carry highest value. Normally in all traditional methods, entrance through a sub-direction is prohibited. The main door and main gate of any plot or building is the most important factor in Vastu Shastra. Hence it should be in the most auspicious directions as suggested by Vastu.
