Decode has commenced construction on ‘Atrium’, Stage One of Carrington Place - Ellipse Property’s five-stage, $750+ million master-planned community at Castle Hill Showgrounds. Occupying 17 amalgamated sites along Carrington Road, Ashford Avenue and Partridge Avenue in Sydney’s north-west, Carrington Place is the largest residential masterplan in Castle Hill. It will deliver more than 800 new homes, helping to address Sydney’s critical housing shortage.

A recent groundbreaking event was attended by more than 100 partners and stakeholders, including the Mayor of the Hills Shire, Federal Member for Mitchell, and the Acting NSW Building Commissioner.

The groundbreaking was celebrated with a traditional turning of soil as well as a smoking ceremony led by a local Deerubbin Elder, paying respect to the traditional custodians of the land in Castle Hill.

Carrington Place is Ellipse Property’s largest project to date, featuring stunning architecture by the award-winning Tony Owen Partners and Stanisic Architects, with interiors by renowned design firm Studio SC, formerly known as Scott Carver. 

With the newly-built Hills Showground Metro Station unlocking greater connectivity between the Hills and the Sydney CBD, Ellipse Property founder Sam El Rihani said that the groundbreaking marks the start of a thriving new community in Sydney’s burgeoning north-west – a sentiment echoed by Federal Member for Mitchell, Alex Hawke.

"With an ongoing shortage of high-quality, transport-oriented housing in greater Sydney, we’re proud to be delivering hundreds of quality new homes – with significant amenities and proximity to retail as well as the state-of-the-art Sydney Metro system. Together with our partners, we are setting a new standard for modern, community-focused living in Castle Hill,” said Mr. El Rihani.

“North-west Sydney is becoming a hotspot for jobs and growth thanks to our world-class Metro infrastructure. The community has been ready for this change for some time now, and we thank developers like Ellipse Property for bringing that vision to Carrington Place,” said Mr. Hawke.

The masterplan will be constructed across five stages and feature abundant community space, with over 20,000 square metres of outdoor recreational area including a one-kilometre boardwalk connecting the precinct to the nearby Fred Caterson Reserve. The project is seamlessly integrated with the surrounding bushland, with a site boundary that stretches right to the edge of Cattai Creek – immersing residents in Castle Hill’s natural beauty. 

The Hills Showground Metro Station is just two minutes’ walk from Carrington Place, offering fast connectivity to Sydney’s CBD, Chatswood, North Sydney, Macquarie Park and Norwest Business Park.

Atrium comprises 140 over-sized, ‘house-like’ apartments in a range of one, two, three and four-bedroom configurations, some with double living spaces. Uniquely, over 75% of apartments will feature studies or multi-purpose rooms, and abundant storage with various layouts also offering walk-in pantries.

Paying homage to its verdant setting, Atrium’s striking design features a curvilinear exterior echoing the form of Cattai Creek with lush landscaping surrounding the building on three sides. True to its namesake, it will also feature an expansive atrium at the ground floor entrance, further connecting residents to nature.

The development will offer elevated indoor-outdoor living, outdoor kitchens, BBQ areas, an outdoor gym, and rooftop terraces boasting sweeping views of the creek and the wider Hills region.

Atrium will be delivered by Decode, an award-winning Tier 2 residential builder and one of the first to achieve a prestigious Gold iCIRT rating. 

"Housing is a massive investment for any consumer, and it is absolutely vital that they can trust the developer and builder they are dealing with. We need iCIRT-rated developers and builders like Ellipse Property and Decode to be the backbone of our industry, and the type of quality players that are filling the void of the housing supply crisis,” said Acting NSW Building Commissioner, Matt Press.

Apartments at Atrium have been sold predominantly to downsizers and first-home buyers, who are attracted to Castle Hill’s natural beauty, vibrant community and abundant retail and dining options. Speaking at the groundbreaking event, Mayor of the Hills Shire Dr Michelle Byrne said that Carrington Place addressed the needs of the Hills’ changing demographics.

“There are people that have lived in the Hills for 30,40, 50 years, they’re not leaving the Hills - they’re downsizing and choosing apartments. There are also more and more people from outside the Hills who want to be part of our community. I’m looking forward to welcoming these people, and projects like Carrington Place - that build not just apartment blocks, but communities - are the key,” she said.

Atrium is set for completion in early 2026.
