Devlin Street Ryde: Mixed-Use Development in a Growth Corridor

Devlin Street Ryde

Located in one of Sydney's fastest-growing corridors, the Devlin Street project in Ryde required engineering solutions that balanced density with construction efficiency and compliance.

Growth Context

Ryde has experienced significant development growth driven by proximity to Macquarie Park, excellent transport connections, and supportive planning controls. The Devlin Street project contributed to this growth with a mixed-use development comprising ground-floor retail and multi-storey residential above.

Engineering Approach

We adopted a reinforced concrete flat plate system for the residential levels, which maximised ceiling heights within the allowable building envelope. The ground-floor retail required larger spans, which we achieved through post-tensioned band beams that transferred loads from the residential structure above.

Basement and Excavation

Two levels of basement car parking required excavation into sandstone. We designed a contiguous pile wall shoring system that provided both temporary excavation support and permanent basement retention. This dual-purpose approach eliminated the need for separate temporary and permanent structures, saving time and cost.

Services Integration

Mixed-use developments require careful coordination of building services. Residential and commercial areas have different services requirements, and the structural design must accommodate penetrations, risers, and equipment platforms without compromising structural performance. We coordinated closely with the services engineers throughout the design development phase to ensure clean integration.
