The green light was shown after the Natural Environment Research Council - the parent body of client the British Antarctic Survey - signed a construction contract for the station with Morrison Falkland.
The project has had a bumpy ride so far, with Broughton regularly denying reports of delays and claims that the scheme had been axed.
The project, dubbed Halley VI, is set to start on site in December 2007, with a test module being built next spring to allow the construction crew to be trained and for further tests to be carried out on the station.
Broughton said: 'The design is faithful to the competition-winning scheme, which I believe is a testament to the efforts made by the entire project team of British Antarctic Survey, Morrison, Hugh Broughton Architects and Faber Maunsell.
'This has been the most fantastic design journey, which has brought us into contact with so many interesting experts from so many fields. It has been a joy of a project,' he added.
