In Partnership with Southern Design Group

Southern Design Group, through its distinct brands Bankston, Iver and TradCo, redefines architectural hardware with innovative designs, sustainable practices and a roster of inspiring collaborations.

Southern Design Group, a leader in the architectural hardware industry, has built a reputation over 40 years for innovation, craftsmanship and design excellence. Founded in 1982 as the Traditional Brass Co by Graham and Denise Duff, the Adelaide-based company underwent a transformative rebranding in 2018 under the leadership of co-CEOs Emily and Steve Bradley (Emily is the Duff’s youngest daughter), marking a pivotal chapter in its evolution.

The Bradleys’ leadership has guided Southern Design Group through a period of bold expansion, elevating the company’s brands to international prominence.

Today, Southern Design Group has three distinct offerings: Bankston, Iver and TradCo, each providing unique hardware solutions that cater to a range of design aesthetics and functional needs. Bankston represents the premium offering, featuring high-end, design-driven collaborations with leading creatives that push the boundaries of architectural hardware. Iver caters to modern homeowners with trend-led collections that balance style and functionality. TradCo, rooted in restoration, celebrates timeless design with a collection that revives classic styles while maintaining the high standards of quality for which Southern Design Group is known.

Husband-and-wife duo Emily and Steve Bradley bring a shared passion for art, architecture and sustainability to the company. As co-CEOs, they transformed the family-run business into a powerhouse in the architectural hardware industry while maintaining its Adelaide roots. Their leadership has guided Southern Design Group through a period of bold expansion, elevating the company’s brands to international prominence. Steve’s background in environmental science and urban design has shaped his innovative approach to product development, while Emily’s expertise in law and sustainability has driven the business’s strategic growth.

Sans-Arc’s offbeat and playful ethos is evident in every piece, offering a fresh perspective on what architectural hardware can be.

In 2018, the Bradleys rebranded Bankston, positioning it as the premium offering within the group’s portfolio. Under their direction, the brand has distinguished itself through bold collaborations with leading architects and designers, challenging conventional hardware design while pushing the boundaries of form and function.

The Super Collection, Bankston’s first collaboration with Sans-Arc Studio, marked a bold departure from traditional hardware design. Inspired by the Radical Design movement of the 1960s, the collection embraces daring shapes, vibrant colours and unexpected materials. Sans-Arc’s offbeat and playful ethos is evident in every piece, offering a fresh perspective on what architectural hardware can be.

Emphasising materiality and craftsmanship, the Casts collection offers a raw, tactile experience that enhances spaces through character and subtle detailing.

Bankston’s second collaboration, Casts by Edition Office, took a more textural and process-driven approach. Known for its innovative architectural work, Edition Office applied its design philosophy to create a collection that explores the relationship between person and place. Emphasising materiality and craftsmanship, the Casts collection offers a raw, tactile experience that enhances spaces through character and subtle detailing.

This spirit of innovation continued with Bankston’s latest partnership, Hemispheres, a collaboration with Brooklyn-based design studio Civilian. Hemispheres introduces bold geometries and striking finishes, offering modular components that allow for endless configurations. With influences ranging from Art Deco to industrial prefabrication, the collection’s versatility makes it adaptable to any interior style.
