ASTROVASTU studies this relationship by reading the Janma Kundli (birth chart) together with the Makan Kundli (house chart).
The SUN often shows its influence through fire and light. In some charts the kitchen functions better along the eastern wall rather than the traditional south east. When the SUN occupies the eighth house, a south facing entrance may coincide with health challenges or career obstacles. In such charts, opening the western side of the house or allowing strong light from the WEST can also create persistent imbalances in life.
Water features tell a similar story. Houses associated with particular placements of the MOON may comfortably support underground water tanks even though classical Vastu would normally treat them with caution.
Planetary combinations can also appear through symbols inside the home. Certain homes benefit from imagery of deer if Mars and Saturn are in the tenth house of the birth chart, while other charts respond favourably to elephants, dogs, goats, or lush greenery. These elements often act as subtle balancing influences within the environment for the individual.
Even the shape of the house may sometimes reflect planetary strength. When VENUS is strong in the second house, homes frequently appear in a Gaumukhi form, narrow at the entrance and wider at the rear, a layout traditionally associated with prosperity.
