[3] Hart's art has been exhibited both in traditional gallery spaces and unconventional spaces such as "a semi-derelict flat above an abandoned frame-maker's shop" in Folkestone, as part of the 2014 Folkestone Triennial.

[4] Her artwork addresses questions of social class,[4] familial behaviour,[5] and the connections between relatives.

[2] Hart's initial training was in photography, but she has gradually focused more and more on sculptures using ceramics.
