An enthusiastic champion for sustainable architecture, Hattie welcomes every opportunity to engage with practitioners in the UK and abroad who are leading the way. Trained as an architect and urban planner, she now works as journalist, writing primarily on sustainable design. She participates widely in industry juries in the UK and abroad, chairs events and lectures on mainstreaming green design. Other interests include Olympic legacy (particularly in London and Rio de Janeiro) - and Brazilian architecture and urbanism. She is a UK ambassador for the LafargeHolcim Awards for Sustainable Construction. Hattie is the author of London 2012 Sustainable Design: Delivering a Games Legacy (Wiley, 2012), editor of Invisible Architecture: Atelier Ten (Laurence King, 2015), and co-author of Energy, People, Buildings (RIBA Publishing, forthcoming). She guest-edited AD 241 Brazil: Restructuring the Urban (Wiley, 2016) prior to the Olympic Games in Rio de Janeiro. Raised in America and trained as an architect and urban planner at Massachusetts Institute of Technology, she has lived in London since 1991. After 15 years in practice in Brasília, Washington, D.C. and London, serendipity and the opportunity to interview Oscar Niemeyer led her into journalism in 1998.
