Inspirational leaders, creative geniuses, dynamic entrepreneurs and tireless campaigners - over the past 40 years, our industry has been blessed with them all. But which person do you think is, or was in their time, the best in the business? We're looking for your nominations for the new Building Hall of Fame - and you've got just three days to have your say …

Who's had the biggest impact on the built environment? Who has helped shape the industry or left a lasting legacy that will be felt for decades to come?

Building is looking for the 40 most influential people across the built environment of the past 40 years for the Building Hall of Fame, to be housed in a permanent exhibition at the Building Centre in central London. The event is to celebrate 40 years since our now 163-year-old magazine changed its name from The Builder to Building.

The opening of the exhibition will be accompanied by a supplement to Building, which we will be publishing on 23 June.

We then intend to inaugurate a member to the Hall of Fame every year.

We would like to invite you, the readers of Building magazine, to help decide who should appear in the Hall of Fame exhibition by sending in your nominations. We will then draw up a shortlist of people who will be whittled down to the final 40 by a panel of industry judges.
