yadi saṃvarddhayed gehaṃ sarvadikṣu vivarddhayet.
pūrveṇa varddhitaṃ vāstu kuryādvairāṇi sarvadā.. 256.29

Such a flaw should be carefully avoided in fixing up the pillars making the doorways and also in the dwelling places for if it is allowed to remain in them, it means the destruction of the household The house should not be extended in one direction only If extension is to be made, it should be made uniformly and symmetrically in all directions If it is to be extended towards the east it creates enmity.—28-29
