Our flat has a south-facing main door — is that bad according to vāstu?
no — vāstu itself has good entrance positions on every side, and in flats light, air and cleanliness matter more than one direction.
South-facing homes have an unfairly bad reputation. Classical vāstu divides each side of a building into padas (sections) and identifies auspicious entrance positions on all four sides, including the south. Many prosperous homes and temples face south. The fear mostly comes from popular simplification, not from the texts.
Vāstu was written for independent houses on open land. In an apartment block you cannot choose the door, the orientation or the plumbing, and traditional authorities themselves say a flat should not be judged as strictly. What you can do: keep the entrance clean, well lit and uncluttered; place a Gaṇeśa image or a toraṇa of mango leaves above the door; put the mandir in the most peaceful corner available; and let in morning light.
Please avoid breaking walls or spending heavily out of fear. A home filled with kindness, prayer and order is already a well-placed home.
