About us

Our vision is to transform ideas, through an engaging creative process, into quality architecture that supports, inspires and delights, for positive environmental and community impact, and a sustainable future.

Enriching lives, enriching place

Our design process applies creative enquiry and analysis to ideas that explore and express unique project, lifestyle and business opportunities, challenge the norm, and develop appropriate architectural solutions, through an interactive collaborative methodology. We combine vision, innovation and value with creative problem solving, efficient planning, rigorous technical detail, and responsible use of materials. Our core design values of sustainability, access and equity are integral to our process.

Our principles

Our design principles uphold, respect, respond to and enhance our clients’ unique needs, desires and aspirations and the opportunities presented by the site, the brief and the budget. They address context including topography, flora and fauna of the natural landscape; scale, density and amenity of the urban environment. They adhere to best practice conservation or adaptive re-use of heritage buildings and environments. They apply the aesthetics of harmonious visual proportion, form, materials, and the interplay of scale, space and volume.

They integrate energy efficient, environmentally sustainable design (ESD) through passive / active solar design, passive house design, low toxic healthy environments, appropriate storm / wastewater management, recycled buildings and materials. They include socially sustainable design that reinforces culture, a sense of place and identity, and builds community.

Our practice

Directors James Morrison & Yvette Breytenbach migrated to Australia in 1991 and the spectacular World Heritage Cradle Mountain – Lake St. Clair Overland Track attracted us to Tasmania. We settled in Hobart where we established our architectural practice, which operates from the repurposed Halls Machinery Building and demonstrates our commitment to sustainable design. We bring worldwide cultural and architectural insight and experience to our practice, gained in South Africa, UK and USA.

The practice is pre-qualified with Department of Treasury and Finance for Strategic and Project Services. Both directors and all professional staff are members of the Australian Institute of Architects (AIA). Being an AIA A+ registered practice we comply with AIA Continuing Professional Development (CPD) requirements, which keeps us informed and inspired by relevant, up to date information and skills.
