London designer James Christian has created a series of architectural parasites intended to occupy empty rooftops, car parks and greens of dilapidated estates across the capital for his residency at the city's Design Museum.

James is an architectural designer whose work spans interior design, urbanism, architecture, objects and interactions. He often uses humour as a means to exploring socio-political themes, as evidenced in his Royal College of Art masters project Free[tr]aid. This imagined a future where a cash-strapped UK had to privatise its international aid programme, leading to an Indian Aid Earning zone in north London. James also worked with aberrant architecture on its terrific tiny mobile theatre which was inspired by one of London’s most unusual entertainment impresarios.
