Diane Archer, researcher with IIED's Human Settlements group, spoke with Somsook Boonyabancha, secretary-general of the Asian Coalition for Housing Rights (ACHR) and International Institute for Environment and Development (IIED) Board of Trustees member. Somsook answered 4 key questions about urban density, watch the interview below.

Part One:

Bangkok is a city of over 7 million people, and land prices are high. Can the many residents on low incomes still find a place to live?

What are the main differences between community-driven and developer-led approaches to low cost housing construction?

Part Two:

Does housing for the urban poor have to be in high rise form?

Is there a link between housing density, social relations and the sense of community in low income settlements?
