The Team

As an innovative design team based in Cape Town, Square One Landscape Architects works across all scales of urban design, architecture and engineering to produce plans and details that are integrated across an entire project. They are refined and stand apart from the rest for all the right reasons.

Amy Feng


Amy completed her Bachelor of Architectural Studies (BAS) degree at the University of Cape Town (UCT) in 2005, where she studied architectural theory and design; creating buildings with creative and functional interior spaces. In 2007, she further obtained her Master in Landscape Architecture (MLA) degree at UCT, expanding her knowledge in the field of landscape design, where the emphasis was rather on the design of outdoor spaces with an ecological approach. Having trained in both disciplines, Amy is meticulous in spatial design, detail design and technical detailing.

Amy’s MLA thesis was titled: “In-situ upgrade of informal settlements through securing public spaces", where she motivated that improvement of public spaces in townships such as Khayelitsha, is the first step to improving the living conditions in less privileged neighbourhoods.
Previously having worked at a leading landscape architecture firm based in Cape Town, Amy has been involved in a broad range of projects focused on public spaces, such as the Green Point Urban Park, and prior thereto on other projects such as the Green Market Square upgrade and the Gugulethu Sports Centre. She has gained extensive experience and knowledge in project management, master planning, detail design and play equipment design.

At Square One, Amy assumes the duties of a landscape architect, and currently assists in the business management of the firm, and performs project management on designated projects.
