Allocation of rooms as per Vastu (In a simple residential building)
Figure shows a conceptual layout of plan of a simple 2 bedroom house.
Bedrooms - The Southwest portion of the house is meant for bedroom for
adults. It may be located in the South, and will be congenial for comfortable
living. Master bedroom may be on the upper storey, if any, in the Southwestern
portion of the house.
Sleep - One should never sleep having head towards the North Pole and legs towards the South Pole. However one may sleep have legs towards the West and head towards the East for mental peace, good thoughts and spirituality.
Children room - Children room should be in the northwest or West Side. To have a better concentration they should have a separate study close to their bedrooms.
Kitchen - Location of kitchen has health implications. Presiding deity of the Southeast is Agni, the God of fire; hence kitchen may be located at the southeast corner of the house.
Study room - One should face the North or the East or the Northeast while studying and he will be shining more. Therefore the best locations for study room are the north, east, or northeast. These directions attract the positive effects of Mercury increasing brain power, Jupiter increasing wisdom, Sun increasing ambition and Venus helps in bringing about creativity in new thoughts and ideas. Books may be kept in the Southwest side of the room. Study room may have door on the East or the North, or the Northeast
Dining room - The dining room should be located in the East or the West or the North nears the kitchen. Northwest corner is good for perishable goods. Dinning room may be in the Northwest direction, which leads to quicker consumption of food.
Bathrooms - East is the place for the bathroom. Attached bathroom may preferably be in the North, or the East of a bedroom. Shower, bathing tub and wash basin in the bathroom may be in the Northeast, or the North or the East direction. One may have bath in the North or the East area in the bathroom. Bathroom should never be constructed in the center or in the southwest corner of the house.
Drawing room - Drawing room should be preferably in the Northeast or the North or the East but not in the Southwest portion of the house. More vacant space should be given in the Northeast corner of the drawing room.. Door is preferable on the East towards the Northeast side.
Store room - Storeroom should be made in the Northwest or Southwest portion of the house. It is very beneficial if grains and other provisions are stored in the Northwest store. All heavy things may be stored in the Southwest of the storeroom. Garbage may be collected in the Southern side portion of the house.
Height of the building should be uniform to get the most advantageous results. There must be uniformity among projections or elevations. The higher or lower level of the building in any of the eight directions leads to different kinds of effects.
There can be slight variation in these directions depending upon the location of site and people birth place. We have to look for astrological calculation for suitability of spaces for different people.
