Nestled in the civic heart of Sydney’s financial district, 39 Martin Place by Tzannes emerges as a benchmark example of civic-minded commercial design. Strategically positioned above the southern entrance to the Martin Place Metro Station, this 28-storey tower commands more than a skyline presence—it encapsulates a forward-thinking architectural response to urban density, infrastructure integration, and historical sensitivity.

Historical Context and Urban Integration

Martin Place itself has long served as Sydney’s ceremonial and financial spine, marked by prestigious bank buildings and public spaces. Among these is the heritage-listed 50 Martin Place, a 1920s Commonwealth Bank edifice with neoclassical grandeur. The redevelopment of 39 Martin Place is part of the Sydney Metro City & Southwest project, a transformative infrastructure investment aiming to optimize transit, encourage commercial development, and revitalize the public realm.

Initially engaged as a peer reviewer, Tzannes was eventually appointed architect for the site after undertaking thorough urban design investigations. These studies informed new development controls, which allowed for greater vertical density while ensuring sensitive transitions to the existing built environment. The result is an urban framework that prioritizes connectivity, sunlight access, and a seamless blending of civic, commercial, and heritage elements.

Design Principles: A Dialogue Between Eras

Respecting Heritage Context

A principal design challenge was reconciling the needs of a new commercial high-rise with the historic architecture of Martin Place. Rather than mimicry, Tzannes pursued architectural dialogue: engaging with heritage through rhythm, proportion, and materiality. The verticality and base articulation of 39 Martin Place reflect the monumental columns and cornices of 50 Martin Place. Window groupings and fenestration reinforce this continuity, subtly expressed in a contemporary idiom through modern detailing.

Material Palette: Texture, Longevity, and Contrast

The building employs a judicious selection of enduring materials: ceramic tiles, Finnish granite, and curved glass. These were selected not only for their durability and low maintenance but also for their relationship with the stone surfaces and textures of the neighboring heritage context. Ceramic panels were used to create depth and detail on the façade, distinguishing the tower’s elevations while allowing it to sit respectfully within the streetscape.

Public Realm and Station Integration

One of the standout achievements of this project is its synergistic integration with the below-grade Sydney Metro infrastructure. Tzannes provided a civic entry to the underground station, complete with glazed entries, landscaped plazas, and natural light channels carved into the podium. Street connections from Martin Place, Castlereagh, and Elizabeth Streets foster permeability. The building is not just an office tower—it’s a civic gateway.

Building Techniques and Construction Approach

Tzannes adopted a premium construction methodology to achieve durability, architectural clarity, and long-term sustainability. The curved structural glass façades, both technically demanding and visually commanding, provide acoustic and thermal performance while avoiding any visual weight. Ceramic cladding was employed not only for its texture but also its robustness against Sydney’s climate conditions and pollution levels.

Internally, the building is designed with flexibility in mind. Raised access floors, column-free spans, and high floor-to-ceiling ratios offer Class A office environments easily adaptable to tenant needs. Sustainability is embedded not just in energy efficiency, but in material lifespans, adaptive reuse potential, and minimized embodied carbon.

Comparative Global Context

39 Martin Place’s thoughtful balance of heritage dialogue, infrastructure integration, and contemporary function puts it on par with several global urban renewal exemplars:

• Hudson Yards, New York City – Built atop an active railway yard, Hudson Yards similarly masters new commercial density over transport systems, integrating office, retail, and public realm investment.
• King’s Cross, London – A regeneration effort combining heritage structures with new commercial and civic uses, with heavy emphasis on through-site access and pedestrian public space.
• 1 Bligh Street, Sydney – Though residentially adjacent, 1 Bligh demonstrates sustainable skyscraper design with a central atrium, curved glass facade, and integration with public terraces. Unlike 39 Martin Place, it does not straddle transport infrastructure nor directly mirror a historic companion.

Practical Insights for Architects and Developers

For architects, especially those engaged in civic or transport-adjacent urban sites, 39 Martin Place showcases how heritage does not need to be preserved as static, but can be catalytic. Referencing—not replicating—historical elements through scale, pattern, and material engages the city’s continuity while addressing present-day performance and function.

Developers and infrastructure planners can take note of the project’s integrated approach where public transport investment underpins value creation above ground. The inclusion of generous public connections builds goodwill, drawing pedestrian flow and contributing to precinct activity.

Sustainability in this context is holistic. It includes durability, heritage stewardship, urban resilience, and lifecycle adaptability. These should be considered early in the design process to reduce long-term delays and costs.

Conclusion

39 Martin Place sets a new precedent for civic-oriented commercial architecture in Sydney and beyond. Neither purely a backdrop nor monumental for its own sake, it fulfills a delicate yet confident role within one of the city’s most iconic streetscapes. Through its rigor in urban design, meticulous material selection, and bold architectural language, Tzannes has crafted a scheme that is not only of its time but designed to endure well into the future.

For professionals working at the intersection of history, density, and infrastructure, the lessons from 39 Martin Place are powerful: architecture can elevate daily experience, civic unity, and commercial value—simultaneously.
