An official ceremony signalled the beginning of works on a 12-storey hotel, retail and office hub being constructed in Werribee.

Representatives from Wyndham council, the Pelligra Group, the InterContinental Hotels Group and Werribee MP Tim Pallas on Monday visited the site on the corner of Synnot Street and Duncans Road.

Owned by Wyndham council, the site is one of four public carparks which will be transformed into high-rise complexes as part of the Werribee “Catalyst” project.

Mayor Mia Shaw said the council has entered into a public-private partnership with Pelligra for the $49.5 million Synnot Street project.

Cr Shaw said the development – which will include a 150-room Holiday Inn, retail areas, office space and an education centre – would become a “lasting legacy” in Werribee. It will also include 362 parking spaces, 167 of which will be public.

Cr Shaw said the future hotel would give visitors to Werribee more accommodation options to choose from, within the town centre.

“Wyndham is currently experiencing significant tourism growth, and the introduction of international flights to Avalon Airport will see these numbers continuing to rise,” she said.

“This hotel will add to the accommodation available for visitors to stay in, while also boosting our local economy.”

The hotel development is set to open in October next year.

Independent analysis has found the Catalyst project will boost Wyndham’s economy by $465 million and deliver 1600 jobs, through construction and ongoing employment.
