Mike Jenner spent five years training at the RWA School of Architecture. Whilst a student he admired the work of Le Courbusier. Following his studies he set up an architectural practice in King Street, Bristol with Ray Moxley.
Although he had strong modernist leanings he realised that much of Bristol's post war revitalization of the city centre destroyed several Georgian and Victorian buildings which would now be protected form such action. His firm received several civic trust awards and commendations.
Mike Jenner has also written for the 'Bristol Evening Post' and had a broadcasting career as a commentator on architectural issues. He defended Bristol's Spectrum Building after its opening in 1984 and has been a lively antagonist of the more conservative approach to architecture voiced by Prince Charles.
He is a Fellow of the Royal Institute of British Architects and a Fellow of the Royal Society of Architects.
