Anchored in the rapidly transforming Mamre Road Precinct, the $489 million Summit at Kemps Creek will deliver one of Western Sydney’s largest new warehouse estates, directly supporting the region’s freight and logistics network and the future Western Sydney International Airport supply chain.
The State Significant Development application has now secured conditional approval from the NSW Department of Planning, Housing and Infrastructure, following detailed assessment of traffic, construction impacts and proximity to three schools and an aged care facility.
Project Overview
Summit at Kemps Creek comprises a concept masterplan for eight warehouse and distribution centre buildings totalling 244,809 square metres of gross floor area. The scheme also includes ancillary offices, a café, hardstands, 1,027 car spaces and supporting infrastructure across a 52-hectare IN1 General Industrial site.
Stage 1 will deliver three warehouses totalling 79,888 square metres, alongside bulk earthworks, estate roads, landscaping and partial construction of the future Southern Link Road. The balance of the site will be prepared for five additional warehouses under the approved concept framework.
The development is expected to generate up to 1,981 construction jobs and 1,716 operational roles at full build-out, reinforcing the Mamre Road Precinct’s role as a major employment hub within the Western Sydney Employment Area.
The site sits opposite Mamre Anglican School, Trinity Catholic Primary School and Emmaus Catholic College, with the nearest school approximately 30 metres from the boundary. This proximity became a defining feature of the assessment process.
Planning Pathway and Amendments
The application was lodged in March 2024 and later amended in February 2025. The amendment incorporated partial delivery of the Southern Link Road and responded to agency feedback regarding traffic, earthworks and infrastructure coordination.
No public authority objected to the proposal. However, detailed submissions were received from Penrith City Council, Transport for NSW, Sydney Water and neighbouring schools. These submissions shaped a number of design refinements and conditions of consent.
The development was ultimately determined under delegated authority, as there were no public objections and Council did not object.
Responding to a Constrained Site
The site’s steep topography required significant cut and fill to create development platforms. Building pads have been carved into the ridgeline to reduce visual prominence, with maximum heights capped at 14.6 metres — well below the 20-metre control.
Setbacks and landscaping soften the transition from the precinct’s rural edge to its emerging industrial character. The masterplan commits to 10 per cent tree canopy cover, with early planting along Mamre Road and the Southern Link Road corridor intended to mitigate short-term visual impacts.
Loading docks are oriented away from sensitive receivers wherever possible. Meanwhile, earthworks volumes and retaining wall heights were reduced following independent expert review during assessment.
Traffic and School Interface
Traffic impacts and school safety emerged as the central issue in the Department’s assessment.
Approximately 1,500 students attend the three schools directly opposite the site. As a result, the Department required construction access to be taken from Mamre Road rather than Bakers Lane, with strict restrictions during school zone times.
The applicant amended the scheme to include partial delivery of the Southern Link Road, which the Department deemed critical to separating industrial traffic from school movements. A Construction Management Committee, including school representatives, will oversee ongoing coordination.
Construction traffic is restricted during peak school periods. In addition, real-time monitoring and consultation mechanisms are mandated throughout the construction phase.
Determination and Conditions
The Department approved the development subject to comprehensive conditions. Key requirements include:
• Southern Link Road infrastructure to be delivered prior to completion of earthworks
• Restrictions on construction traffic during school zone times
• Ongoing consultation with adjacent schools
• Real-time noise and air quality monitoring
• Independent auditing and compliance reporting
The Department concluded the proposal is strategically justified, suitable for the site and in the public interest, provided mitigation measures are implemented.
With approval now in place, Summit at Kemps Creek is positioned to become a major logistics estate within the Western Sydney Aerotropolis corridor, reinforcing the Mamre Road Precinct’s rapid transition from rural land to industrial employment hub.
