The Bob Watt Studio in the grounds of Kinghorn Town Hall was officially opened on Tuesday by Mr Watt’s partner Jeannette Malcolm.
Mr Watt, who died in May 2012, was a trustee with Fife Historic Buildings Trust, as well as a renowned architect and prolific local fundraiser for charity.
The building, which was recently restored by Fife Historic Buildings Trust, was originally a guard room for jail cells within the neighbouring Town Hall and will now house the Trust’s offices.
Jeannette Malcolm said: “Bob was a very modest man and the improvement of Fife meant everything to him.
“I know he would be very honoured by this recognition from the trustees of the Fife Historic Buildings Trust.”
Christine May, chairman of Fife Historic Buildings Trust, said: “Bob is greatly missed by all of us at Fife Historic Buildings Trust, and now we have a fitting way to remember his enthusiasm and professionalism.
“I am sure our staff will be inspired to even greater achievements with Bob’s name on their new premises.”
Bob Watt was born in London in 1938 but grew up in Airdrie.
After qualifying as an architect, he moved to Methil to continue the practice of Peter Sinclair, architect in the town since 1924.
He had a positive impact on many people throughout his life and career with Sinclair Watt Architects.
He was a founding trustee of the Levenmouth Development Trust whose primary objective was the improvement of the area for the local community.
Kinghorn Town Hall and Guard Room date from 1830 and were designed by architect Thomas Hamilton in the Tudor Gothic style.
They are statutorily listed category B and form a central feature within Kinghorn Conservation area.
The Town Hall was restored by Fife Historic Buildings Trust in 2008 as part of the Kinghorn and Burntisland Townscape Heritage Initiative and now houses a unique holiday apartment.
