Approval has been given to build a modern art gallery on a site where 19th Century artist JMW Turner stayed on his visits to Margate, Kent.
David Chipperfield's gallery will be clad in white opaque glass
Planning permission for the Turner Contemporary was granted by Thanet District Council on Wednesday.
The two-storey building, designed by architect David Chipperfield, will be clad in white opaque glass to reflect the light which inspired Turner.
The gallery, which is key to Margate's regeneration, is due to open in 2010.
Work is scheduled to begin in autumn.
"This is a tremendous step forward and we remain on schedule for the creation of this landmark building or Margate," said Kent County Council (KCC) cabinet member Mike Hill.
"A vast amount of work has gone into this project and we will soon see it really taking shape."
David Chipperfield, who won the Royal Institute of British Architects (Riba) Stirling Prize last year for The Museum of Modern Literature in Germany, was appointed in July 2006.
An earlier design for the Turner Contemporary, in the sea off Margate, was scrapped when projected costs rose to £50m.
KCC then put a ceiling of £15m on the cost of the new gallery, though it later rose to £17.5m.
The Turner Contemporary is seen as central to the growth of the town's cultural quarter and prosperity of the Old Town.
As well as exhibition galleries, it will have education space, a cafe and a shop.
Thanet council said the ground floor gallery would have spectacular views out to sea.
Roadworks to connect the Fort Hill site with the Old Town and the seafront and improve pedestrian access are to begin in April.
