As an established architectural firm located in Melbourne, we specialise in the design of small to medium multi-residential developments, new single dwellings and residential extensions. We are a multi-lingual office with Project Architects available to communicate in English, German and French.

Our collaborative design process between client, consultant team, and relevant authorities ensures outcomes that are founded on design excellence whilst also personalised and relevant to their surroundings. Each project is an intelligently considered proposal which seeks to exceed client aspirations whilst maximising the site’s unique opportunities. This, for us, is key to the development of an architecturally rich project.

Atelier 1:7 is committed to applying sustainable design principles to our projects to create homes that are a pleasure to inhabit.
