European Roma Mapping (EU-ROMA) was a Europe-wide 3 year research project on Roma dwelling and housing. David worked on the UK research for the project with Sue Konu at Project 35, in collaboration with artist Lucy Orta and the London College of Fashion. The project led to conferences and exhibitions across Europe, including at the Royal Institute of British Architects and Conway Hall (London), and in April 2010 to the publication of the edited collection Mapping the Invisible, published by Black Dog.
