Alexandra Buchanan Architecture

Alexandra Buchanan Architecture | Brisbane Team

With Studios in both Brisbane & Melbourne, we have projects along the length of the East Coast of Australia.

Alexandra Buchanan Architecture was founded in 2011 by Architect & Director Alexandra Buchanan.

Our studios in Brisbane & Melbourne create beautiful, liveable architecture, interiors & landscapes that respond to your story and how you want to live.

Our portfolio includes a highly diverse range of typologies including one-off residential dwellings, additions to heritage buildings, bespoke office fit-outs, off-grid eco cabins & multi-level apartment buildings.

Our projects manipulate space, light, form and material, to create bespoke environments and unique experiences for our clients.

We want our architecture to uncover something new about a place, to capture the best aspects of a site and provide places and spaces for people to enjoy and provide an opportunity to contribute and connect to the broader community, to complement a place and positively benefit those who use it. For us, it’s not just about a beautiful product – it’s about the journey and the process and we value our relationships with clients.

We make architecture to enrich the human experience, to craft joy and create a deeper connection to a place.

ABA combines a unique team of highly skilled individuals from a diverse range of cultural backgrounds and educational experiences from Australia, South Africa and the UK that bring a greater depth and richness to our design processes and ultimately our projects. With this our team are focused on creating dynamic environments & encouraging appropriate, progressive and collaborative design processes for every project.

Our Vision

Enduring, evocative architecture that is responsive to people and place

ABA’s vision is to create enduring, evocative, beautiful architecture that is responsive to people and place. Our philosophy centres around functional, elegant and personalised spaces that are customised for you, your site and your lifestyle. At ABA we believe architecture should speak to those who inhabit, occupy or utilise it. It should respond to the characteristics and peculiarities of the site whilst expressing the personality, ethos and individuality of its users.


Design with a social, cultural and ecological conscience, always

At ABA we feel incredibly strongly about the impact of the construction industry on the environment and as such we have invested in our team to provide you with an approach that considers the longevity of each project and its impact on the climate. In 2021 ABA has committed to run a carbon neutral studio & now has two fully accredited Passive House Design Consultants.


High quality architectural outcomes no matter the scale or budget

At ABA our skill is in crafting high quality architectural outcomes, no matter the scale or budget. We care about the detail and finesse of each building


Our Team is Passive House Accredited

What does this mean

Certified Passive House is a growing trend in Australia but what exactly does that mean and why are people embracing this voluntary building standard?

A passive house is one that delivers a healthy indoor environment that is comfortable in temperature and humidity, while using very little energy. Originating in Germany in 1990 where it is known as Passivhaus, it is already widely used across Europe and, while a relatively new idea here in Australia, very much a growing trend due to its many cost and health benefits.

Benefits for you

While some people think of a Passive House as one where all the windows and doors are never opened, it is not an enforced sealing up of a building, in fact quite the opposite. You can open the doors and windows when the weather is nice and close it up when it is too hot or cold – essentially live like you usually would. The difference is when it is uncomfortable outside and the house is closed, it is sealed, and you are getting the optimum indoor environment when it comes to health and comfort.

How it works

Our Passive House Accredited Team will lead you through the full spectrum of sustainable solutions to embed in our design vision, whether that be for a full accredited Passive House or a lighter touch sustainable approach that responds to your site & budget constraints.

Our Process

We start each project by learning about your unique story and your lifestyle – your favourite season, time of day, in the belief that residential architecture should speak to you, and how you as an individual and as a family want to live and be in your space.

We explore, test & challenge the brief with you – as well as the peculiarities of your site and its context – to ensure every project is unique, highly considered and intricately tailored to you and its context.

The building process is like an iterative funnel that requires various skills to lean in to the team at various stages to inform the design as it develops. Our role in this aside from designing for you is to share our wealth of contacts and experience to ensure we have the right people lean in to join you on your journey.
