House Overlays: The Arenas Where Relationship Plays Out

Beyond planetary aspects, synastry reveals where one person’s planets fall in the other person’s houses, showing which life areas are activated by the relationship.

When your partner’s Sun falls in your 4th house, they illuminate your sense of home and family, potentially helping you feel more secure in your foundations. If their Venus falls in your 10th house, they might enhance your public image or career ambitions through their affection and support.

Partner’s Planets in Your 8th House: Creates deep transformation, intimacy, and potentially challenging power dynamics in areas related to those planets.
