Brighton-based artist Claudia Fontes created an art installation, ‘Glasshouse Stories', exploring the hidden lives of plants and the complex relationships between nature, history and migration.

The installation was selected as the winning proposal from an open commission organised by Brookfield Properties and AWITA, supporting new sculptural work by women artists in public spaces.
