Under the regulatory landscape of New South Wales, developing high-rise residential towers requires more than just standard engineering capability; it demands legislated compliance expertise.
For developers, architects, and builders in Sydney, securing a structural engineering team that is fully registered under the Design and Building Practitioners (DBP) Act is a mandatory step for Class 2 developments.
JSBC Consulting confirms that our principal engineers are registered Design Practitioners under the NSW DBP Act. We possess deep, proven experience in delivering compliant, practical structural frameworks for complex, large-scale residential precincts and high-rise towers.
What is a Class 2 Building?
Before commencing any multi-residential project in NSW, it is vital to understand its classification, as this dictates the regulatory path.
According to the National Construction Code (NCC), a Class 2 building is broadly defined as a building containing two or more sole-occupancy units, each being a separate dwelling.
This classification typically includes:
High-rise residential apartment towers.
Multi-unit residential complexes.
Mixed-use buildings where a significant portion is residential living quarters.
For the precise definition and latest updates, refer to the ABCB (Australian Building Codes Board) National Construction Code.
Understanding Your Obligations Under the NSW DBP Act
The NSW Government introduced the DBP Act to restore confidence in the construction sector by ensuring residential apartment buildings (Class 2) are designed and built to high standards.
Crucially, the Act requires that regulated designs—including structural and façade engineering—must be prepared by a registered Design Practitioner. Furthermore, a Design Compliance Declaration must be issued before building work commences. This is not an optional step; it is a legislative requirement to ensure the structural integrity and safety of high-density living spaces.

Our Experience with Complex Class 2 High-Rise Towers
Compliance is just the baseline. The true challenge in Sydney’s market lies in engineering structures that are buildable, efficient, and capable of handling complex loads.
JSBC Consulting specializes in Tier 1 high-rise residential projects. Our teams are adept at solving intricate structural challenges, such as transferring massive tower loads through transfer podiums, designing deep basement retention systems, and engineering frameing for significant wind loads.
Our portfolio demonstrates extensive experience in delivering large-scale Class 2 infrastructure:
Prime Macquarie Park: A massive mixed-use precinct featuring four residential towers up to 22 storeys, totaling 680 apartments. JSBC engineered an iconic, multi-storey structural tripod to resolve complex load transfers for the high-rise towers.
The Archibald, Gosford: A landmark twin-tower development consisting of two 28-storey high-rises housing 289 residential apartments and a hotel over a common podium. Our team optimized high-rise load paths while navigating complex ground conditions.
One City Square: A “city within a city” master-planned precinct. JSBC delivered the complex structural design for a 42-storey tower and a 22-storey residential tower, supported over a colonnaded podium and a five-level deep basement.
Vivacity Stage 2, Sydney Olympic Park: A significant mixed-use precinct including 583 residential apartments across six towers, reaching up to 30 storeys in height, situated over a large transfer podium structure.
