This is a series of photographs of Sydney basement car parks. The Sydney Basin, extending 380kms along the east coast of NSW, is known for its beautiful sandstone, quarried since European settlement. Now that cars seem to rule, we excavate massive underground car parks, using enormous cutting discs which often leave behind circular patterns in the stone. The stone’s porosity allows moisture to seep through and due to the lack of bleaching sunlight, layers of algae and other microbial elements combined with the rock’s coloured sediments can build up exquisite patterns. These photographs are the actual walls in these basements.
