Builder-developer Urban Property Group (UPG) is continuing to expand into new markets. UPG is heading to the Hills District, where it is planning a 40-storey mixed use building near Castle Hill Metro Station.

They've gone down the favoured developer route of a State Significant Development Application, which should see developments approved within the space of nine months.

The tower will comprise 371 apartments, 42 of which will be affordable housing, above a ground-floor retail precinct at 16-20 Old Castle Hill Road, on the corner of Garthowen Crescent and within walking distance of Castle Hill Metro Station, an area identified for higher density under both local and state strategic planning frameworks.

Designed by Studio SC, the tower would rise from a brick podium base, accommodating one retail tenancy and communal open space, before transitioning to a slender glazed residential form above. Six basement levels are proposed beneath the building to house parking and services.

“Castle Hill is undergoing a significant transformation, evolving from a traditionally low-rise suburban centre into a true metropolitan destination anchored by the Sydney Metro Northwest," the Architectural Design Report prepared by Studio SC noted.

The majority of apartments (194) will be two-bedrooms. 90 one-bedroom apartments are planned, 83 three-beds, and four four-bedroom apartments.

Studio SC’s design adopts a podium-and-tower composition, with warm-toned masonry at the lower levels intended to anchor the building within its streetscape context.

"At the podium, the architecture is anchored through solid brickwork in warm, earthy tones, reflecting the local sandstone formations and the natural colour palette of the surrounding hills," Studio SC added.

Above, the tower transitions to a lighter glass expression, articulated with fins and tonal variation to reduce visual bulk and respond to changing light conditions.

Urban Property Group is one of Sydney's most active developers. They have projects currently under construction in Little Bay, Penrith, and Macquarie Park, with future projects earmarked for Wollongong.

Castle Hill has been one of the most popular suburbs for development across Sydney in the last five years, as developers scramble for land around the newly extended Sydney Metro. 

Kassis Homes kicked it all off with Grand Reve, along with Deicorp who has delivered over 1,000 apartments in the area and continues to develop. The likes of Dubai-backed developer Arada will take to market their project in the coming months, while Masscon has just launched Avenue on Cadman Crescent.
