The chairman of Sellar Group died on Sunday following a short illness.
Sellar was best know for the Shard which was completed in 2012.
He was a massive presence on the UK property scene and his son James will now become head of the group which his father founded in 1991.
A spokesperson for Irvine Sellar said: “Irvine will always be remembered for his determination ‘against all odds’ to create and develop The Shard, a building that changed London’s skyline forever.
“The property industry has lost an immense and irreplaceable character whose sheer grit and determination will leave a huge void in a sector known for big characters.”
