What does the model house represent in the play, Tiny Alice?

The model house is the most important symbol in the play. The house in which Tiny Alice lives where Julian will join her is sealed tightly. In this respect, it is like the "glass dome" that "descended " on Julian before he entered the asylum. The sealed world of the model also represents the unrealistic world Julian has tried to create for himself since then. He had sought safety in the Church but that institution turns out to be his greatest enemy. The model, which captivates Julian, ends in symbolizing his death.
