Synastry House Overlays
House overlays show where your partner's planets fall inside your natal houses — the life areas where their energy is felt most strongly.
What is a synastry house overlay?
In synastry, the house overlay technique places your partner's planets onto your natal chart. The house in which their planet lands tells you where their energy will affect you — your identity (1st), your home (4th), your relationships (7th), or your intimacy and shared resources (8th).
