The Hansen team culture is built on pride and passion for our work

The multidisciplinary nature of our practice applies to not only what we do, but how we do it. Our services may be defined by the fields of urban planning, urban design and landscape architecture, but in reality we apply a spirit of collaboration to everything we do.

Associate - Landscape Architecture


Castiel is a landscape architect with seven years’ professional experience in local and international practice. Castiel’s design philosophy centres around design that respects and reveals the natural context and history of a site through a process of attentive observation, creative interpretation and innovative construction. She has comprehensive experience and a keen interest for projects located in sensitive ecological environments requiring particular attention given to the natural dynamics and biodiversity of the site and the site’s role and function within its context.

Castiel’s background studies in landscape architecture, horticulture, art, urban and environmental planning bring a broad knowledge base that contributes greatly to the Hansen Partnership’s collective creativity and ability to respond to diverse client needs and expectations. In particular, her extension into planning broadens her understanding of the relationships between the practice of landscape architecture and urban planning and how the two can coexist with the natural and built environment.

Castiel provides creative and technical design in the delivery of complex urban, residential and environmental development projects. Her extensive history of success executing and managing landscape architecture and urban design projects is borne from her strong artistic, interpersonal and communication skills. These strengths assist our team when engaging with stakeholders, conducting community engagement workshops and presenting creative and sustainable design solutions to meet client needs and expectations.
