Jonathan Woolf ((1961-02-13)13 February 1961 – (2015-09-04)4 September 2015) was a British architect.

He was born in London and educated at Kingston School of Architecture at Kingston University before apprenticing at practices in Rome and later in London, where he was project architect for the house of art collector Charles Saatchi.

In 2003 the practice completed Brick Leaf House in Hampstead, North London, which received a RIBA Award[2] and a Civic Trust Award, and became the first private building to reach the mid-list of the UK Stirling Prize.

Building Design hailed Brick Leaf House as "a statement of real capacity" and in 2004 honoured the practice with the Building Design Architect of the Year Award.

The practice won international competitions in Milan for furniture and in Dublin for urban regeneration and in 2007 received an Honorary mention and 7th place amongst the 1,170 entries of the international competition to extend Eric Gunnar Asplund’s 1930s Stockholm City Library.
