Client testimonial

Work on the homestead is nearing completion and we are very pleased with the outcome. Your design is everything that we hoped for and it was completed with no variations other than the deletion of the trophy and wine cabinets.

Gregors Creek

Dion Seminara played a key role in the renewal of St Peter and Paul Church at Bulimba. He was able to understand our requirements and responded generously and creatively. It is a beautiful space… and it won an architectural award!

Father Tom

We engaged Dion Seminara Architecture to help find a more aesthetically pleasing solution to using a baby gate to fence off an area for our dogs. His design solution was nothing short of brilliant – both in form and function.

We are astounded at the way that Dion managed to effectively understand our brief, understand our passion for interior design, gauge our style and uncompromising standards and immediately provide options that were on-point.

In addition to interior works, Dion made us aware of improvements that we had not even considered; all of which will provide, what is an ordinary street facade, with the WOW factor. All of the suggestions made are being embraced and Dion will oversee all works.

W have an immense amount of respect for his talent, and that of his team. He is professional, punctual and accommodating.


Thank you so much for your knowledge and expertise. We valued your service and it was very helpful in allowing us to picture how to wisely plan out each minor and major step. A major encouragement for us!

Low Commitment Consultation

Step 1 in our process begins with our Design Options Assessment – needs and options review, our low commitment consultation offer to our clients. Many years ago we constantly saw people rushing into their design process and building works without having fully completed their research and analysis. The consequence of this is similar to building a home on bad foundations. It’s very expensive to change the foundations when you are already building on top, but it’s very easy to change them if they are lines on a plan. Therefore, in order to spend a little more time on research instead of rushing into design we conduct an analysis of your needs and wants = lifestyle, and explore design options and ideas with you.

Tailored to you

Your home reflects who you are, and we want the finished product to be something that you are proud to call your own.

Our experienced Brisbane architects create homes and environments that inspire and excite, while simultaneously providing a comfortable space to call home. We understand the needs of our climate and environment. Given Brisbane’s often inclement weather and predilection for flooding, we place emphasis on making sure that homes are flood-resistant and eco-friendly wherever possible and necessary.

Our expertise means that we understand traditional Queenslander designs, pre-war renovations and modern homes. Every design that we create considers the way in which the modern family lives and interacts.

Call us today on (07) 3899 9450 to discuss your design needs and speak to our principal architect, Dion, about your new future home or commercial project.

Welcome home

Your dream home is possible

  • Ready to create your dream design?

    An architecturally designed space is so much more than just a dwelling. When working with you to develop a home or space, we consider the liveability, functionality and overall aesthetic so that we can deliver a technically sound and specific design that intuitively meets your needs. We think about light, space, the interplay between the seasons and your preference for dining outdoors – and then create a design that will tap into how you truly want to live in your home. We would love to meet with you and discuss what you have in mind for your home or commercial project, so please contact us today for a design consultation.

  • Professional services

    When you work with us, you will enjoy access to not only our architectural services — which include building and interior design — but also landscape and grounds design, concept through to approval stages, tendering and complete project management. We can provide as much or as little input as you want or need and will be on hand with creative direction throughout the process.

  • What stage are you at?

    Whether you’re getting started on a new build and want the peace of mind that comes from enlisting the guidance of a professional Brisbane architect, or you are looking for a concept to kick-start the process, we can help. Our team of creative and passionate design experts are on hand to guide you in the direction you want to go. We love turning your dreams into an on-paper design and then creating a reality.

    Our realistic and unique designs let you be as passionate and involved with the creation of the design as you desire, while still comfortable with the budget that you need to facilitate this investment. Because after all, an architecturally designed home is an investment, and you will enjoy a home that retains and grows in value over the years.

  • Consultations

    We are available to consult on pre-design advice and assessment as well as pre-purchase design advice. Whether you’re looking to kick off a home renovation or create a new home from scratch, we have a process in place that makes the planning and design simple. We can guide you on things like budget, specifications, council guidelines, planning and approval, and realistic constraints and/or possibilities.
