The RIBA Stirling Prize is judged against a range of criteria including design vision; innovation and originality; capacity to stimulate, engage and delight occupants and visitors; accessibility and sustainability; how fit the building is for its purpose and the level of client satisfaction.

The Stirling Prize 2023 ceremony takes place in Manchester on Thursday 19 October 2023 at Victoria Warehouse, an iconic cultural venue. The winner will be announced at the event live alongside a number of special awards.

The RIBA Awards are the most rigorously judged prizes for architectural excellence in the UK, with the winning buildings then eligible for the prestigious RIBA Stirling Prize. 

Born in 1996 out of its predecessor, The Building of the Year Award, The RIBA Stirling Prize is presented to RIBA Chartered Architects and International Fellows for buildings in the UK which have made the greatest contribution to the evolution of architecture over the past year.

The RIBA Stirling Prize is named after James Stirling. Stirling won the Royal Gold Medal in 1980 'in recognition of past achievements which exist in their own right, as well as the potential of unbuilt projects, both past and future, which are an inseparable part of the Stirling vocabulary'.

Often described as a 'prophet without honour in his own country', he did not live long enough to achieve the public recognition and success his peers achieved after his untimely death. He died, at the height of his powers, following a routine operation.
