WELCOME TO SOUTHMARC

Interior of a modern living room with concrete walls, a large abstract artwork on the wall, a light gray sofa, a textured rug, and a decorative branch with white blossoms in the foreground.

Founded by Nikki South, Southmarc Architecture has been shaping thoughtful, enduring homes since 2004. From Hong Kong’s hills to the beauty of Lisbon, to Sydney’s leafy suburbs, Nikki’s global experience and local insight define a practice devoted to architecture at the scale of everyday life.

As a Fellow of the Australian Institute of Architects, Nikki’s work has been recognised with awards and featured in The Sydney Morning Herald, Indesign, House & Garden, and Grand Designs. Yet the heart of Southmarc lies beyond accolades—in creating spaces that give back to their inhabitants and their surroundings.

ABOUT US
Open French doors leading to a bedroom with a bed, nightstand, and green accent wall, outside plants and flowers.

At Southmarc Architecture, design begins with two questions: Who is it for? How will it give? Every home, whether an intimate renovation or a multi-residential project, is shaped by these principles. We design with light, landscape, and history in mind—crafting architecture that feels both grounded and alive.

No fixed style. No formula. Just a continuous pursuit of balance, beauty, and purpose.

Open glass doors leading into a bedroom with a bed, dark green wall, and a small side table with a plant.
