Simon Allford

Simon Allford (born July 1961, in Sheffield, UK) is a British architect, and is the co-founder and director of Allford Hall Monaghan Morris (AHMM). He is a past President of the Royal Institute of British Architects (RIBA), and serves as a member of both the Board and Award judging panel. Allford was previously the chair of the board of trustees of The Architecture Foundation (2013-2018), a trustee of the Architectural Association Foundation, and the Vice President for Education at the RIBA. He is currently a trustee at the London School of Architecture and Chickenshed Theatre Trust.

The son of architect David Allford, chair of YRM, Simon Allford was born in July 1961. He attended the University of Sheffield and the Bartlett School of Architecture, where he has since worked as a lecturer. Allford is a visiting professor at the Harvard Graduate School of Design and The Bartlett.

In 1989, with Jonathan Hall, Paul Monaghan and Peter Morris, he established AHMM. The practice today employs over 450 people working on projects in education, healthcare, housing, arts and offices. In 2017, it became majority employee-owned through an employee ownership trust.

AHMM was awarded the RIBA Stirling Prize in 2015 for their design of Burntwood School, in Wandsworth, London. The judging panel said of the project: "Burntwood School demonstrates the full range of the skills that architects can offer to society… It encompasses great contemporary design and clever reuse of existing buildings as well as superb integration of artwork, landscaping and engineering."

In November 2013, it was announced that Allford would be the new chair of the board of trustees of The Architecture Foundation. Allford was elected RIBA President (2021–2023) in August 2020.
