the practice

environa studio, founded in 1986, is a highly innovative architectural practice, with an emphasis on the triple bottom line of social, environmental and economic responsibility.

We design for public and private clients. Projects include urban design, masterplanning, civic, commercial and multi-residential buildings, eco-tourism, group housing and retirement villages. All our projects have an emphasis on environmentally and socially driven community projects.

We are a multi-disciplinary practice of 10 professionals, headed by principal architect Tone Wheeler and managing partner Jan O’Connor. By integrating architecture, planning, interiors and landscape, we seek a deep understanding of our clients’ brief and site to produce an individual response.

environa studio emphasises design flexibility, so as to create dynamic solutions in short time frames. Our solutions are creative and experimental, but always practical and liveable. We have written widely on architecture and sustainability and are often quoted in the media for our activism.

practice philosophy

environa studio has a design philosophy based on 5 fundamentals:

  • The purpose of each project will reveal a detailed brief that addresses the real needs of our clients.

  • The place, its site and climate, will develop an environmentally appropriate architecture.

  • The proposition of a strong design concept leads to contemporary solutions with innovative spaces.

  • The use of precedent in form and typology will make culturally and socially appropriate solutions.

  • The patterns of construction will make the most appropriate use of materials and energy.


We are seeking ways to live in a far more environmentally conscious fashion, from increased communality in the building forms, to better land, energy and water use. Through traditional and innovative typologies, we aim to achieve greater efficiencies and a lower carbon footprint. We are reinterpreting the positives of past urbanity for a more sustainable future.
