House siamese shillelagh is a 13-cell still life.

As its name implies, this still life can be seen to contain a house and shillelagh sharing cells. It very closely resembles bookend siamese shillelagh.

This is the smallest way to stabilize a house. As a house can act as an eater 1 if both sides are used at once, it sometimes gets used in symmetric oscillators despite being asymmetric itself.
