Donington chief Simon Gillett has dismissed a UK government report that was highly critical of the circuit's plans to ready the venue for the 2010 British grand prix.
The Commission for Architecture and the Built Environment (CABE) said the project, including track reprofiling and new facilities, are "disappointingly weak".
The report said the plans fall "far short of what the local authority and the nation should be aspiring to in a modern formula one venue".
But chief executive Gillett, who has secured a ten-year contract to host Britain's round of the world championship at Donington Park beginning next year, pointed out that the refurbishment plan is being overseen by renowned F1 architect Hermann Tilke.
"Tilke GmbH is a company that has worked on the majority of outstanding motorsport circuits worldwide and understands the requirements and compromises that have to be made to deliver a fully functional, workable, deliverable and yet still very striking grand prix circuit," he told the Daily Telegraph.
