The designs for redevelopment of Donington Park, the future home of Formula 1 racing in Britain, "weak" and a "missed opportunity".
A report by the Commission for Architecture and the Built Environment (Cabe), said the proposed plans show a "a poor understanding of the site and the opportunities it offers".
The park's owner Simon Gillett was granted permission to develop the site by North West Leicestershire District Council earlier this month. He signed a 10-year agreement with Formula 1 supremo Bernie Ecclestone last summer to host the British Grand Prix.
Silverstone has been used since 1987, but after stalling over a deal it lost out to Donington Park and the final race at the Northamptonshire track will be in June this year.
But the review of the future track was far from positive.
Cabe`s report said: "The material presented gave us little confidence that a bold architectural vision had been developed for this facility to showcase Britain's racing pedigree and create at Donington Park a racetrack of global standing to match Formula 1's most recent tracks in Bahrain, China and Malaysia designed by the same team that are working at Donington."
