PDA powered Newgreens Precinct with expert high-voltage infrastructure and hands-on family leadership.

Power Distribution Australia

The Newgreens Precinct, a landmark golfside development in Sydney’s Chatswood, demanded more than just visionary architecture and luxury finishes—it required robust and future-ready electrical infrastructure. Stepping up to meet this challenge was Power Distribution Australia (PDA), a family-owned business renowned for delivering high-voltage electrical solutions across New South Wales.

Led by Emily and Tony Rossi, the father-daughter team behind PDA brought over 60 years of combined industry experience to the site.

“We were responsible for the installation of a 1000KVA Ausgrid kiosk substation to support the precinct’s energy needs,” said Director Emily Rossi. “That included more than 400m of excavation, conduit and cable installation to extend the Ausgrid high-voltage network—no small feat in a built-up, environmentally sensitive area.”

PDA’s work involved navigating complex site logistics, including tree protection zones, existing infrastructure, and close residential proximity. “We prioritised clear communication with nearby residents and took every measure to comply with electrical authority and council requirements,” Emily noted. “Working within those constraints while maintaining safety and efficiency is where our experience really shines.”

One of the standout technical challenges was the installation of the site’s earthing grid, which required specialised equipment due to the area’s unique soil and construction characteristics.

With over a decade in operation, PDA has built a reputation for precision, safety, and family-driven values. “Having directors who are hands-on and deeply invested in each project makes a real difference,” Emily added. “We’re proud to have contributed to the backbone of a development that blends innovation with community living.”

The Newgreens Precinct now stands powered and future-ready—thanks in no small part to the expert hands at PDA.

Smart Access, Waste, and Mobility Solutions for Newgreens Precinct

Traffix delivered smart, tailored transport solutions to overcome access, waste, and mobility challenges at Newgreens.

Traffix

Since late 2019, Traffix Pty Ltd has played a pivotal role in shaping the functionality and accessibility of the Newgreens Precinct. As a mixed-use site with a diverse set of transport needs, including residential, hospitality, and golf club component, the project demanded tailored, high-performing traffic and transport solutions.

“Our scope was comprehensive,” says Ben Liddell, Director at Traffix. “From the initial Traffic Impact Assessment to
post-approval construction planning, we worked closely with Parkview and Willoughby City Council every step of the way.”

The team addressed key challenges early—particularly the steep grade difference between Beaconsfield Road and the precinct’s Level 3 top level. “We had to provide safe, compliant access for everything from passenger vehicles to fire trucks and ambulances. It required extensive modelling and precision design to meet the Australian Standards for both grade and width,” Ben explains.

One unique obstacle was accommodating waste collection within the basement. “Typical garbage trucks just wouldn’t fit. Our solution involved mini waste trucks and redesigning the basement ramping to suit them,” says Ben.


Traffix also integrated sustainability into their strategy, recommending 48 bicycle parking spaces, dedicated bike lanes, and safe pedestrian links to bus stops and surrounding infrastructure. A private minibus service was also planned to assist resident mobility.

Collaboration was key to success. “We had over five years of ongoing coordination with architects, engineers, and the builder. From design reviews to swept path analyses, we ensured our traffic planning matched the project’s overall vision,” notes Ben.

Even during the challenges of 2020’s remote working conditions, Traffix remained committed. “Online meetings were new to us all, but we adapted quickly to keep progress moving.”

Digging Deep for Success: Safety, Sustainability, and Efficiency

Chalouhi’s civil works prioritise safety, sustainability, and efficiency, ensuring successful early and civil works at Newgreens.

Chalouhi

Chalouhi was engaged to complete extensive early and civil works that enabled the successful transformation of the former Chatswood Golf Course into the $250 million Watermark luxury retirement living community.

Their scope included demolition, soil remediation, bulk and detailed excavation, rock face stabilisation, installation of permanent ground anchors and construction of temporary haul roads. They have managed in delivering the project on time with high quality while prioritising safety, sustainability, and efficiency. “We leveraged our in-house plant and machinery to manage critical aspects like demolition, excavation, and traffic planning, ensuring control and flexibility across the 51-week project,” said Christine.

The site’s previous use as a golf course presented major environmental and logistical challenges. Chalouhi managed the Green Star-rated demolition of a 3-storey clubhouse and remediated over 15,000m² of contaminated material across the site, including asbestos-affected soil Sustainable practices were also prioritised throughout the project, with over 70,000m³ of sandstone being crushed, recycled and reused onsite. In particular, 25,000m³ has been used to construct a 2,500m² temporary access road, minimising material waste and noise disruption.

Traffic management was another key component. Oversized equipment, including 40-tonne dump trucks and 110-tonne surface miners, had to be carefully transported via narrow local roads. Chalouhi worked closely with local councils to secure permits and reduce community impact.

In addition to environmental remediation and complex logistics, Chalouhi undertook detailed planning to ensure their works integrated seamlessly with other construction activities. Their expertise in sequencing multiple operations (ground anchoring, stabilisation, and utility preparation), was essential in maintaining project momentum.

Chalouhi’s strong stakeholder communication, proactive problem-solving, and real-time project tracking helped keep the project on track. Their coordination of complex, multi-disciplinary work streams showcases their expertise in high-density, multi-stage urban developments. A commitment to sustainability, quality, and collaboration has made them a trusted partner in shaping Sydney’s future communities.

Sun, Glass and Smart Design

Renyi ensured sustainable, code-compliant design at Newgreens, balancing energy efficiency with architectural vision.

Renyi

As Australia embraces greener urban development, the Newgreens Precinct demonstrates how architectural vision and sustainable engineering can work in harmony.

Playing a central role in that success is Renyi, a Sydney-based consultancy specialising in sustainable building design and performance compliance. Led by Director Allan Ang, Renyi was tasked with ensuring the project met environmental goals without compromising the architectural intent.

“We focus on providing professional design and architectural advice that delivers not only code-compliant solutions but enhances the environmental sustainability and visual value of each project,” says Allan. “Our goal is always to support projects that will contribute to cleaner, greener cities.”

At Newgreens, Renyi’s primary role involved Section J energy efficiency assessments, as outlined in the National Construction Code (NCC). This included evaluating the façade and services systems to ensure code compliance, buildability, and resource efficiency. “Our job was to assess the performance of the façade and the services—like insulation, ventilation, and air conditioning—so that we could provide realistic, code-compliant solutions,” explains Allan.

A standout challenge was the clubhouse, which features a dramatic west-facing glass façade and an articulated butterfly roof. While visually striking, the design posed comfort and performance risks, particularly in Sydney’s harsh afternoon sun.

“The façade was elaborate—mostly glass and west-facing. It created comfort challenges,” Allan said. “We had to carefully assess and apply glazing performance data to meet both thermal comfort requirements and the architect’s design vision.”

The angled roof also complicated insulation and HVAC installation. “The roof wasn’t flat—it was tilted and sculptural. That made it difficult to run services efficiently. We identified those issues early and worked through several iterations to ensure performance standards were met.”

Through thermal calculations and simulation modelling, Renyi proposed energy-efficient yet achievable solutions that aligned with construction requirements and regulatory obligations. Their focus was not just on compliance, but on real-world performance.

“This wasn’t about introducing high-tech systems—it was about getting the fundamentals right,” says Allan. “Section J is about energy efficiency, but the outcome is comfort. It’s about choosing the right materials, so the space doesn’t overheat, and the aircon doesn’t have to work overtime. That’s how you reduce long-term carbon impact.”

Renyi’s contribution extended across the entire precinct, including independent living units and communal facilities. Their approach prioritised early-stage collaboration to align performance requirements across teams.

“There were a lot of meetings and coordination,” Allan recalls. “Each time a new party came on board, it introduced new perspectives—and new challenges. It really highlighted how important it is to engage the right people at the same time to resolve complex design issues.”

Renyi’s strength lies in this collaborative clarity, helping balance client expectations, construction practicality, and environmental ambition. Their role at Newgreens reflects a broader commitment to delivering sustainable building solutions that are both technical and tangible.

“The Newgreens Precinct is architecturally refreshing,” Allan reflects. “The clubhouse is a beautiful building, and it was rewarding to work on the independent living units too—knowing that our input supports thermally comfortable, sustainable homes for older Australians.”

While this wasn’t Renyi’s first aged care or retirement development, it was a standout for its design complexity and layered stakeholder environment. For Allan, the project was a reminder of the power of early integration and honest collaboration.

“We’ve seen how critical it is to involve all consultants early,” explained Allan. “When you do, you save time, reduce rework, and achieve better results.”

Renyi continues to lead with practical, code-informed solutions that champion both comfort and creativity. The Newgreens Precinct stands as a prime example of that mission in action.
