मुख्यद्वार · mukhya-dvāra
Traditional (Shastra)
Entrance is judged by pada on the 32-pada perimeter; northern and eastern auspicious padas are favoured.
Scientific rationale
East/north openings admit soft morning light and, in most of India, avoid harsh afternoon heat on the door zone.
पाकशाला / अग्निकोण · pākaśālā / agni-koṇa
Traditional (Shastra)
South-east is the Agni (fire) corner; cooking facing east is recommended.
Scientific rationale
A SE kitchen receives morning sun that dries and lights the space; prevailing SW monsoon winds can carry smoke away from living areas.
देवगृह · deva-gṛha
Traditional (Shastra)
Īśāna (north-east) is the zone of the divine; the Brahma-sthāna should stay open.
Scientific rationale
A quiet NE room gets gentle early light, suitable for meditation; no direct physical effect is claimed.
शयनागार · śayanāgāra
Traditional (Shastra)
Nairṛtya (south-west) gives stability to the head of household.
Scientific rationale
Thick SW walls buffer afternoon heat; sleeping with morning light from the east supports circadian rhythm.
शयनकक्ष · śayana-kakṣa
Traditional (Shastra)
West and north-west are suitable for younger members and guests.
Scientific rationale
Bedrooms with morning or diffuse light and cross-ventilation are cooler and better for sleep.
शौचगृह · śauca-gṛha
Traditional (Shastra)
Waste is kept away from Īśāna and the Brahma-sthāna.
Scientific rationale
Placing wet areas on hotter western walls helps them dry; separation from the kitchen and water source is hygienic.
सोपान · sopāna
Traditional (Shastra)
Heavy structures go to south and west; stairs ascend clockwise.
Scientific rationale
Heavy masses on the S/W act as thermal shields; an open NE keeps daylight and air paths clear.
जलस्थान · jala-sthāna
Traditional (Shastra)
Water belongs to the north-east; fire and water should not share a zone.
Scientific rationale
Keep any well far from the septic tank (commonly 15 m or more) to avoid contamination — this is a real hygiene rule.
Traditional (Shastra)
Heavy load on SW; keep NE light.
Scientific rationale
A tank on the SW roof shades the hottest roof area; check structural load with an engineer.
Traditional (Shastra)
Waste is placed in Vāyu (NW) region, away from Īśāna.
Scientific rationale
Locate downslope and away from wells and foundations; follow local plumbing codes.
ब्रह्मस्थान · brahma-sthāna
Traditional (Shastra)
The central padas of the Vastu Purusha Mandala belong to Brahmā and are kept free.
Scientific rationale
An open central court improves stack ventilation and daylight in deep plans.
सभा · sabhā
Traditional (Shastra)
Public functions toward north and east.
Scientific rationale
North light is steady and glare-free; good for occupied daytime rooms.
भोजनशाला · bhojana-śālā
Traditional (Shastra)
Adjacent to the kitchen, west preferred.
Scientific rationale
Proximity to the kitchen reduces carrying distance; ventilation matters more than direction.
विद्यागृह · vidyā-gṛha
Traditional (Shastra)
West (Varuna) and NE support learning.
Scientific rationale
Diffuse north/east light suits reading; desk facing E or N avoids screen glare from the west sun.
Traditional (Shastra)
Movable objects in Vāyu (NW).
Scientific rationale
Places a heat-absorbing, rarely-occupied space on the hotter side.
अलिन्द · alinda
Traditional (Shastra)
Open verandahs are traditionally placed on the north and east so that the north-east stays light and open.
Scientific rationale
North and east balconies get gentle morning sun and avoid the hottest afternoon sun in most of India.
