The hotel, which was gutted by fire in 2007, reopened its doors to patrons last weekend as Carnegies Fremantle.
The pub was bought by its current owners, the international Carnegies chain, which has hotels in Perth’s CBD, Hong Kong, Taiwan and China, in June last year.
The venue now includes a rooftop bar, a historic front bar, as well as 11 boutique hotel rooms.
Classic Contractors managing director Mark Stewart said the project was particularly challenging considering the heritage value of the 130-year-old hotel.
“When we took over, it was basically a shell, you could look up in the middle of the building and see the sky,” he said.
“There was no power or water to the site, and being a building that’s 130 years old, having requirements of what needs to be done from a heritage point of view and also the owners’ requirements of what they wanted was quite challenging.”
Mr Stewart said the National Hotel revamp was also a handy boost to the company’s profile, and a good showcase of its capabilities.
The redevelopment took 18 months to complete.
Elsewhere in Fremantle, another rooftop bar has recently opened its doors, on the roof of the old Myer building at Kings Square.
