Pitt Street North Over Station Development
The Pitt Street North over station development (OSD) is set to create a vibrant mixed-use hub in the heart of Sydney’s retail, dining and entertainment precinct. The 39 storey premium office tower is located above the northern entrance to Pitt Street Station, creating a new gateway to Sydney’s CBD.
Pitt Street Station forms an integral part of Sydney’s evolving metro system, with the new North OSD adding further benefit. The OSD has an elevated lobby and retail plaza, fronting onto Park Street – one of the most prominent east-west cross-streets in Sydney. The northern station’s design on Park Street is expressed by the recessed groove form of the podium and building form, adding value to the street’s aesthetic and assisting with intuitive wayfinding.
The office building’s flexible, large-span floorplate aids visual connectivity across floors, with a design that includes a dynamic entry experience. Taking visitors through a series of spaces that includes a sky lobby and a retail and dining offering, the building’s ‘third space’ environment seeks to ease the transition between public and private. Key to the design is the clear separation of the entrance to the metro station and entrance to the commercial lobby, furthering the divide between station and office.

The integration of the Pitt Street North commercial building that will sit above the new northern Pitt Street metro station entrance, has been an exciting challenge. The concept developed by Foster + Partners carefully responds to its context and functional requirements, and COX are in the process of completing the architectural and interiors documentation to deliver the outcome.
A-symmetry is celebrated by articulating the height of the building’s roof. The plant rooms at the top of each tower volume are stepped to create three distinct and unique roof elements of different heights. Sandstone cladding to the podium and bronze-toned cladding to other parts of the tower responds to the local heritage context, while creating a distinct appearance to the building.
The North OSD project aims to meet market-leading sustainability targets. The building has highly efficient mechanical systems including passive chilled beams, PV panels on its roof, a high-performance façade that incorporates external shading and maintains strong views, and shading systems that reduce radiation that hits the glass.
The building elevations will be angled away from Park Street to reduce the width of the building’s southern façade. Additionally, the alignment of the north facade has been angled away from the adjacent buildings to minimise impact on solar access to Hyde Park. The building and podium massing will be softened by rounding the corners – combining this with angling the building facades will allow for open views where possible.
This project has been undertaken in collaboration with Foster + Partners, with Foster + Partners preparing the concept design, and COX responsible for the documentation and construction phases as Executive Architect. Drawing upon the global experience of Foster + Partners, the building responds to key trends in major office building projects.
