When a play is called A Doll's House, chances are that home might be a prevalent theme. Early on in the text, the home is seen as a thing of joy, a place of comfort and shelter. The idea of home is enmeshed with the idea of the happy family, which the Helmers seem to be. Towards the play's conclusion, however, the imbalance of power in the family becomes an issue. Now the seemingly happy home is revealed as having been a façade, a doll's house, hiding the gulf between the Helmers. The Helmers' home is really more of a prison than a shelter.
Over the course of the play, Nora's conception of her home goes from a place of shelter to a prison.
It is ironic that most of the other characters envy the Helmers' home.
