Sarah Wigglesworth MBE RDI is a British award-winning architect and Professor of Architecture at Sheffield University.

Together with her partner, Jeremy Till, Wigglesworth was the first architect to be awarded the Fulbright Arts Fellowship.  In 1998 the Sunday Times named her as one of three architects in their "Hot 100" poll.  She was awarded an MBE in 2004.

Wigglesworth founded Sarah Wigglesworth Architects (SWA) in 1994.  Her practice developed a reputation for ecological buildings and a particular fascination for the use of alternative materials, including straw, in architecture. One of the practice's best known buildings is the Straw Bale House (and Quilted Office) in Islington, London, which features widely in architectural periodicals. The building was designed as a house and office for Wigglesworth and Till, using straw bales, cement-filled sandbags, silicon-faced fibreglass cloth and gabions filled with recycled concrete.

She has been Professor of Architecture at Sheffield University since 1999 and founded the PhD by Design in 2002. Her academic work often blends with her live projects and she describes her research focus as "revealing the workings of practice".

Wigglesworth has been Chair of the Judging Panel for a number of years, for the Jane Drew Prize, which celebrates inclusiveness and diversity in architecture.  In 2012 she was appointed a Royal Designer for Industry, the first ever woman to awarded this prestigious title for architecture.
