Alba and Luna

Westbourne Constructions, a distinguished name in Sydney’s construction industry, was at the forefront of delivering the Alba and Luna developments in Green Square, both designed and developed by Bridgehill Group. These architecturally ambitious projects feature two striking buildings offering 360 meticulously designed apartments and penthouses at 499 Botany Road, Zetland.

As the design and construct builder on both developments, Westbourne was responsible for the full delivery—from early site establishment, dewatering, and structural construction through to detailed internal fit-outs and final handover. “We managed all construction phases, coordinated with key stakeholders, and ensured that every element aligned with the client’s vision for quality and functionality,” said Project Manager Matthew D’Arcangeli.

Designed in collaboration with McNally Architects and Sissons Architects, Alba blends modern urban living with the industrial heritage of the area. The distinctive terracotta masonry façade pays homage to the precinct’s brickwork legacy while delivering durability and thermal efficiency. A mix of one, two, and three-bedroom apartments and double-storey penthouses feature flexible layouts, abundant natural light, and intelligent interior detailing.

However, the project came with complex challenges. “The site’s urban location and large footprint required meticulous planning and smart sequencing,” said Matthew. “Basement construction was carried out seven metres below the water table. We worked closely with Cetco, Waterproofing Assurance, Aqua Remedial Works, and National Pump & Energy to implement a fit-for-purpose tanking and dewatering solution—particularly during one of the wettest years on record.”

The team also delivered a unique architectural feature on the Luna building—8-storey high brickwork chimneys on the northern elevation. “These chimneys, built with dry-pressed bricks in a faceted layout, demanded artisan skill from Paragon Group. With radii as tight as 300mm, it was a small miracle and a true focal point of the façade,” he said.

Throughout the build, Westbourne followed its rigorous Integrated Management System, ensuring quality, safety, and environmental compliance. “Stage-by-stage quality checks, daily safety briefings, and real-time progress tracking allowed us to deliver consistency across both sites,” D’Arcangeli said. “This approach helped us achieve Federal Safety Commissioner accreditation, which we’re very proud of.” Sustainability was embedded in both projects from the outset. Internally, the buildings incorporate energy-efficient lighting, high-performance insulation, and smart climate control systems.

Shared amenities include electric vehicle charging stations, bicycle storage, a pet wash bay, and a landscaped sky garden, enhancing community connection while reducing environmental impact. Efficient plumbing fixtures and a planned water recycling system further support long-term conservation goals.

Collaboration was central to Westbourne’s delivery model. “From early design development through to final detailing, we worked hand-in-hand with Bridgehill, the architects, and consultants,” said Matthew. “Regular workshops helped us refine materials, problem-solve in real time, and maintain buildability without compromising design.”

The developments are set within the fast-growing Green Square precinct, offering residents unmatched access to the Gunyama Park Aquatic & Recreation Centre, Drying Green Park, Green Square Library, and transport links, including Green Square Train Station.

Looking forward, the team views these projects as a blueprint for future success. “Despite COVID-19, material shortages, regulatory changes, and weather disruptions, we delivered on time and to a high standard,” Matthew said. “The project reinforced the importance of early contractor involvement, adaptive planning, and strong communication.”

From world-class amenities and landmark architecture to environmentally conscious design, Alba and Luna stand as testaments to Westbourne’s commitment to innovation, craftsmanship, and collaborative delivery—an approach that continues to define their legacy in the Australian residential construction landscape.
