Darren Kaye

Topology Studio was founded by directors Amy Hallett and Darren Kaye in 2012. Together, Amy and Darren bring to their practice a combined 50 years of experience in delivering projects with inherently complex and unique briefs, and a passion for exacting design standards. The practice has grown to creative team of 6 people.

Topology Studio’s designs are informed by the unique attributes of each site, in particular the physical landscape and the climatic conditions, to create bold, rich and meaningful places. Their work combines a design-intensive, creative approach with robust, process-driven architecture.

Having spent a decade as Associate Director at one of Australia’s most respected architecture practices, Darren has extensive experience leading residential, commercial and hospitality projects across all scales. His innovative approach to design is driven by an interest in the way sustainability principles can enhance the inhabitant’s experience of architecture, as well as the broader environment.

Amy’s experience working for leading design architects has developed her passion for detail and conceptual legibility. She has worked on numerous public, residential and educational projects in Australia and overseas, notably The British Library Centre for Conservation and The Jewish Museum in London.

Collaborations

Drawing on the knowledge and experience of multidisciplinary professionals and experienced contractors ensures logical and robust decision making. Open and collegiate collaboration with during both design and construction stages is instrumental to promote meaningful exchange and achieve a quality outcome.

We seek opportunities to work long side other Architectural practices and with independent designer-makers. The ability to fabricate bespoke items that have been designed specifically for a project opens up the possibilities beyond the range of commercially available architectural hardware and fittings. We are fortunate to be based in Melbourne amongst a rich and diverse community of creatives.

In consideration of sustainability and supply chain accountability we specify locally designed and produced furniture, fabrics and lighting whenever possible. Local production also enables standard products to be customised to suit particular projects.

The city of Melbourne has a wealth of design events with which we engage. We have participated in public events such as Open House Melbourne and the Robin Boyd Foundation’s Open Day and spoken publicly at events hosted by the Robin Boyd Foundation, The Concrete Masonry Association, Green Magazine and Architeam. We have engaged in conversations within the design community through written articles for various print and on-line architectural and design publications.
