From a quarry high in the mountains of north Wales to the bustling heart of Perth more than 60,000 pieces of slate have been shipped to breathe new life into a city landmark.
Just weeks before the first set of scaffolding comes down at the Old Treasury Building redevelopment, _The West Australian _was given a first look at the exhaustive restoration works being done at the historic site.
The building, the heart of the $584 million Treasury-Cathedral precinct on St Georges Terrace, is set to become a premier hospitality centre with restaurants, bars, shops and an exclusive hotel.
But before the interior fit-outs and refurbishments start, a team of experts have been given the task of returning the 135-year-old building to its former glory.
Kyle Jeavons, project senior development manager at FJM Property, the developers behind the project, said they had picked some of the best known and respected heritage subcontractors in the country to deliver a restoration of international quality.
The building, which has been vacant for two decades, needed a complete strip-out and upgrade including reinstating of the slate and copper roof.
Nigel Carter and his team from Carter Roofing have spent the past six months nailing in the high-quality slate, piece by piece.
They have even enlisted the help of Welshman Dennis Owen, a roof slater of 19 years, who has been lending his expertise in training apprentices in the traditional techniques, which have been all but forgotten as cheaper, quicker alternatives hit the market.
"It's a dying trade - something often considered too hard to learn and too costly for builders who want a quick, cheap fix," Mr Carter said.
"But slate from a good quarry is the most cost effective form of roofing - it is guaranteed for 100 years."
Chris Holdich, of Built Holdings, the contractors behind the project, said no expense had been spared in ensuring the best possible heritage result for the building.
"It is a testament to the developers that they are willing to invest in materials that are not only best for the longevity of the building but also ensure the heritage integrity of the final product," Mr Holdich said.
The project is due to be completed in early 2015.
