Shelter is one of those core needs along with air, food, water and clothing. But the house seeks to fulfil other functions: security, belonging, esteem and self-actualisation. In The Castle, three artists from different generations explore divergent ideas of home. Frank Nowlan uses it as a base for vernacular observation and deadpan characterisation. Rob Howe places the house within the streetscape, painting the overlap between light, cast shadow and gestural geometries. Christopher Zanko pares back and records housing types as markers of urban change. The Castle is an opportunity to view three significantly different painters initiating a conversation around ideas of home.
