The former head of regeneration in Birmingham who worked on projects such as The Cube and Library of Birmingham has died aged 62.
Clive Dutton OBE was a well-known figure within Birmingham's business community during his time as director of regeneration and planning for Birmingham City Council - a role he left in 2009 to move to London to work on the 2012 Olympic regeneration legacy.
He also helped to re-shape the regeneration of west Belfast following the signing of the Good Friday Agreement by producing the 'Dutton Report'.
Mr Dutton received the OBE for services to urban regeneration in 1998. Tributes have been paid today following his death on Saturday.
Writing on the Millennium Point website today, chief executive Philip Singleton called him an indefatigable man who finished his working day later than anyone he knew.
The pair worked together for six years at Birmingham City Council and the Olympic regeneration project in Newham, a period Mr Singleton called "intense".
"Such is the manner of city planning, Clive's ideas are fulfilled and often completed by others. Every day I look at Birmingham and I see the library, New Street station, Arena Central, Paradise Circus and the Golden Square," he wrote.
"(At) Eastside City Park, we failed in a Big Lottery bid to fund the new park and that day Clive burst into the council chief exec's office and came out with the money to pay for it.
"City council politics with both the small and large 'P' is a pretty testing place, yet Clive seemed to often create the waves and then ride them.
"He built trust, vision and advocacy for the ruling group, and then he delivered, so his ratings were very high indeed.
"Birmingham can sometimes drop good ideas a little too swiftly, but the Big City Plan was a Clive idea that became one of the biggest tools to configure a future for 800 hectares of city, ever."
Louise Brooke-Smith, who founded and runs consultancy Brooke Smith Planning in Edgbaston, said on Twitter: "Very sad to learn that Clive Dutton OBE has died. He was a tour de force for Birmingham and for the regen world and will be missed by many."
Bob Ghosh, founder and director of K4 Architects, said he had "a truly humbling list of achievements" and Ken Shuttleworth, founder of Make which designed The Cube, called him an "inspiration for Birmingham".
Coun Anita Ward, Labour member for the Hodge Hill ward at Birmingham City Council, said: "So sad to hear the news of Clive Dutton's death. A man with real drive, passion and vision for Birmingham. Thoughts are with his family."
And Labour MP for Northfield Richard Burden said: "Sad to hear that Clive Dutton has died. We differed over approaches to Brum regeneration but he was friendly, approachable & we got on well."
