Thoughtful architecture transforming urban spaces

When I took on the role of back of house Architecture Lead for the Central Station revitalisation and Metro integration, I knew it would be an incredibly complex project. With so many interlocking elements, seamless coordination was essential. My primary focus was that the architectural components of the non-public, functional and technical areas met the rigorous requirements of the brief. Beyond that, I was responsible for facilitating communication and integration between multiple architectural teams and engineering disciplines to deliver the best outcome for public transport customers.

One of the biggest challenges was balancing the space allocation between front of house areas, where customers move through the station and back of house areas, which house essential operational infrastructure. The back of house spaces for the Metro Station account for roughly 50% of the floor area, so maximising space efficiency was key. Our goal was to prioritise the customer experience by dedicating as much space as possible to the public facing areas without compromising operational and maintenance requirements.

To achieve this, we employed several innovative strategies. We repurposed the disused ‘ghost’ platform and baggage tunnels, relocating a significant portion of the Metro Station’s electrical equipment outside of the Metro Box. This approach freed up valuable space within the station while maintaining operational efficiency. We also meticulously planned the layout of rooms and services, so that back of house areas are as compact as possible. Digital modelling played a crucial role in optimising delivery routes for installation and future replacement of equipment, enabling us to streamline circulation spaces without affecting station operations or safety.

These strategies had a direct impact on the quality of the public spaces within the station. By optimising back of house efficiency, we enhanced natural and intuitive wayfinding, improved light penetration into the underground concourse and platform areas and created larger, more open volumes with clear sightlines.

The Metro project also provided an opportunity to uplift the entire station precinct. New entries, better connection and expanded circulation spaces have transformed Central Station into a more legible and integrated facility. The outcome is a station that feels open, filled with fresh air and natural light that offers generous spaces for both movement and moments of pause. Thoughtful design enhances the experience of arriving, departing and simply passing through, making daily commutes more comfortable and enjoyable. 

The way we design and shape our built environment changes everything. My role in this project reinforced my belief in the power of architecture to not only solve complex functional challenges but to improve the way people interact with urban spaces. Thoughtful architecture has the ability to transform not just physical spaces but also how people experience and connect with their surroundings. When spaces are designed with clarity, efficiency and human interaction in mind, they become more than infrastructure, they become places that are part of a journey.

Sydney’s Central Station and Metro platforms stand as a testament to what’s possible when we put people at the centre of design. Through meticulous planning, innovative problem-solving and a focus on the customer experience, we’ve helped create a station that serves its community today and into the future. More than just a transit hub, the station is now a dynamic and welcoming public space that enhances the daily experience of thousands of commuters. By integrating thoughtful wayfinding, natural light and intuitive circulation, we have transformed it into a place that feels open, safe and connected. This project demonstrates how architecture can go beyond functionality to enrich the way people engage with their city.
