Skirt of the Black Mouth is a semi permanent installation at the Tate Modern on London’s South bank. Designed in collaboration with Heather and Ivan Morison the project is a site-specific piece that creates an urban park space. Commissioned by Tate Modern to hide the porta-cabin site office for the gallery the hording takes a new approach to creating a boundary as an architectural and sculptural frame. Made of cast concrete and burnt timber the park covers an area of 6x20x100m
