Established in 2001 and based in London, the office of 6a architects is headed by its founding directors, Stephanie Macdonald and Tom Emerson. This monographic issue takes a look at their work from 2009 until the present. Besides presenting nineteen exemplary projects, it reproduces two extensive conversations with the architects, through which readers can get a better sense of their history, education, relationship, perspectives, design concepts and methods, and much more. Featured works include the Raven Row Contemporary Art and Exhibition Centre, V&A Fashion Galleries, HafenCity Residential Buildings, Hotel Therme Vals, South London Gallery, and more.
