Construction of the new Marriott Hotel in South Australia is now rising above Adelaide’s iconic General Post Office (GPO) building in King William Street.

Led by BESIX Watpac on behalf of developer Greaton, construction has reached Level 4 and is on track for completion in early 2024.

BESIX Watpac CEO, Mark Baker, said the company was excited to be delivering the landmark, 5-star accommodation to support economic growth and tourism for South Australia.

“Construction is now rising up above the original GPO building which is a reflection of more than 120,000 hours worked on site, and 3,100 cubic metres of concrete poured to date,” Mr Baker said. “The new build sits on the site of what was an office tower addition to the original post office in the 1920’s.”

“The remainder of the building, constructed in the late 1860’s and early 1870’s, will remain with some sections being incorporated into the new hotel.

“Currently, new structural and seismic upgrades are taking place between the basement and the roof to ensure structural integrity of both old and new buildings – a major milestone to allow commencement of fit out.”

Once complete, the $200 million luxury hotel will boast 16 storeys and will become the first hotel operated in South Australia by Marriott International.

The property will incorporate 285 large guest rooms, including a Presidential Suite, as well as a Club Lounge, restaurants and bars, swimming pool and fitness centre, plus function and conference rooms.

Greaton Regional Manager for South Australia Wendy Liang said Greaton was excited by the project’s progress and grateful for the strong support of the South Australian Government.

“The project certainly has reached an exciting stage and the skill and talent of our consulting and construction team has been demonstrated,” said Ms Liang. “Heritage works to strengthen and integrate the new hotel with the former GPO are almost complete.”

“Greaton is very proud of this new hotel that will benefit the state’s economy for many years to come.

“A special thank you also to the project team, the consultants, the trades and everyone on the site for their contribution to the project and to a safe workplace.”

SA Minister for Tourism, Zoe Bettison, said tourism in South Australia was in an exceptional position, with hotel bookings over recent months reaching record highs.

“We’ve seen Adelaide accommodation have its strongest week ever during Mad March with an average 9,140 of the 10,521 rooms available sold each night, and regional South Australia now at nine consecutive months of record-breaking occupancy rates,” Ms Bettison said.

“This incredible demand for accommodation in Adelaide and South Australia is exactly what makes hotel investors look to our state, and why globally recognised hotel brands like Marriott International are investing in our city.”

Developer Greaton and builder BESIX Watpac have employed heritage and architecture consultant Lovell Chen to supervise the build including connections and restoration work where the new hotel integrates with the GPO building.

Heritage measures have been implemented in the main postal hall, while specific protection measures have included preservation of the World War 1 Staff War Service Board and some of the pneumatic tubes system.
