Bolton-based contractor G&J Seddon has won the contract to build a £10m new home for Williams Bolton's BMW and Mini dealerships.
The showrooms on Manchester Road will replace the existing Williams buildings on Bradshawgate in Bolton town centre.
Robert Hirst, dealer principal of Williams Bolton, said: "We will be moving our head office into Bolton. Contrary to some rumours circulating, we are not moving the Manchester showroom to Bolton – it is staying where it is. Williams will continue to have strong presence in Bolton, Liverpool, Manchester and Rochdale."
The 12-month construction programme is expected to begin in November this year with completion and opening of the new dealerships taking place in November 2008.
