Urban Property Group to close the curtain on award-winning Thornton precinct with Mayfair on Penrith release

Two years after securing development approval for the final stage of its award-winning Thornton Precinct on the doorstep of Penrith Station, Urban Property Group is set to launch Mayfair on Penrith, around 400 apartments designed to reflect two of Sydney’s most iconic structures.

The builder-developer has continued refining the design plans for the two-building development on a significant 8,280 sqm site on Sheffield Circuit, recognising the importance of the prime parcel as one of the closest developable sites to the station.

UPG enlisted architecture firm SJB to design the project. The team said they drew inspiration from both the General Post Office in Martin Place and East Circular Quay to help shape the design. The two-level colonnade, in particular, reflects the famous GPO building, which dates back to the 1860s.

There will be one-, two-, and three-bedroom apartments on offer, with interiors by Cox Architecture. Residences will sit above a retail podium featuring hospitality and lifestyle operators such as One Playground and Volcano’s Steakhouse, contributing to an activated ground plane within the broader Thornton precinct.

A communal rooftop with a pool and views towards the Blue Mountains will provide shared open space for residents. The development is positioned between Ron Mulock Oval and Westfield Penrith, with the Nepean River and Great River Walk also nearby, placing daily amenity and green space within walking distance.

Mayfair is being delivered by Urban Property Group, a family-owned developer and builder with nearly 40 years’ experience across Sydney. The project will be the first in Penrith to be offered with Resilience Insurance’s 10-year Latent Defects Insurance (LDI) policy, which Urban Property Group has adopted across a number of its recent developments. The developer also has a 4.5-star iCIRT rating, one of the best ratings in market providing further confidence to buyers.

Urban Property Group CEO Patrick Elias said providing additional assurance to off-the-plan buyers has become increasingly important.

“Anything we can do to give confidence in our product is a plus,” Elias told Apartments.com.au.

“Consumers are a lot more weary and a lot more concerned in buying off the plan than they ever have been. They’re making their single large investment, which is their home, and providing confidence is something that we feel is paramount.”

The LDI policy provides a 10-year warranty covering structural defects, with independent inspections carried out during construction and protection for owners if defects arise post-completion.

Mayfair represents Urban Property Group’s sixth and final development within Thornton, consolidating the masterplanned precinct immediately east of the station.

The developer, which builds its own projects, has already commenced construction. SRM Residential is handling the sales campaign.
