A luxury Gold Coast development has become Multiplex Queensland’s first battery-powered building site following a successful trial that sets the pace for cleaner, quieter construction worldwide.

Global building giant Multiplex used a supersized rechargeable lithium battery to power building works on beachfront project COAST, being developed by Sammut Group on the Northcliffe beachfront in Surfers Paradise.

The battery-powered generator was a first for Multiplex Queensland and was trialed during stage one of the project.

“You would normally rely on diesel generators to get everything going because you mostly don’t have power on the site to kick off with,” said Multiplex Regional Manager Glenn Robinson.

“We were able to get a small power connection to the site which trickle fed 100% renewable power from the grid to charge the battery overnight ready to power the entire site during the day.

“There were positives from the trial, both from the 60 tonnes reduction in carbon emissions from our site operations and a better understanding of the capabilities of this new technology – it’s given us confidence to use these systems again in the future.”

The battery system, which reduces the carbon footprint by up to 90%, is 30 times less noisy, and emits zero exhaust fumes compared to diesel generators, is capable of powering tower cranes, welders, hoists, bar benders, and even concrete pumps.

The practice has since been rolled out to other Multiplex Queensland job sites, marking a carbon win for the Tier 1 builder and a sustainability tick for Sydney-based Sammut Group as it makes its Gold Coast development debut.

Announcing the final release of apartments, Sammut Group Managing Director Allen Sammut said his team was elated with progress on COAST.

“To be out of the ground now is a huge boost of certainty and confidence for our buyers in a market where most developers are struggling to secure a builder,” he said.

“In the coming months the four podium levels that house the amenities will be finished and the tower will start. Our intention from there is to pour a floor every four to five days.”

The current timeline would see COAST finalised in the first quarter of 2026, making it among the first to be completed on the Northcliffe strip, which is halfway between Broadbeach and Surfers Paradise and in proximity to The Langham Hotel and the iconic Jewel Residences.

The $250 million project encompasses 52 residences over 37 levels, with four levels of resort-style amenities including two pools, a sunset bar and lounge, and extensive wellness and fitness facilities.

Leading luxury real estate agency Kollosche has been engaged to market the nine remaining apartments, which includes half floor beachfront residences priced from $6,500,000 and offering 287 sqm with three ensuite bedrooms, a powder room, a multi-purpose room, and balconies to all elevations.

The full floor beachfront apartments offer a sprawling 598 sqm – the largest available off-the-plan on Garfield Terrace – and include four ensuite bedrooms, two powder rooms, a multi-purpose room, an entertainment quarter, and 143 sqm of external area.

Kollosche Managing Director Michael Kollosche said the limited supply of beachfront land, protected ocean views and a shortage of new apartments made COAST a very rare find.

“COAST is a stand-out project on this strip,” said Mr Kollosche. “Uninterrupted and protected ocean views are limited along the beachfront and the lifestyle on offer from this location, with four levels of amenities, is outstanding.

“With the supply of new apartments dwindling due to construction challenges, buyers are wise to make their move at today’s prices.”
