Sandstone & Salt is Ava Shirley's pair of homes on Sydney's Northern Beaches. La Petite Palette is a one-bedroom apartment of original art and colour, tucked behind a boutique interior design studio in Manly with its own entrance. The Streamliner is the architect and builder family home in North Manly: four bedrooms, two living spaces and a kitchen that opens straight onto the garden, a flat walk or bike ride from the beach.
