Client testimonial

Dion conducted a pre-purchase inspection for us. Dion’s advice, input and experience was invaluable. Prior to our meeting, Dion spent time on the phone with me and a we completed a questionnaire so he could thoroughly understand our needs both now and into the future. Dion then spent 2 hours with us at the property. He provided great advice about the options and possibilities with the house, taking into consideration the block and aspect, our lifestyle and budget. We gained so much from his knowledge and decided the property wasn’t for us due to the scope of work, time and costs involved – better to know that upfront rather than make a significant purchase that wouldn’t have been right for us. We gained so much information from the session – I typed up 3 pages of ‘gems’ from our meeting! We’ve taken this info over to our house search and that’s helped us to better clarify our needs, and we can better appraise other properties from a more informed perspective, and that’s saving us a lot of time and effort.

I also called Dion a couple of times after our meeting, and he was again generous with practical, detailed info and suggestions. I’d be happy to engage Dion again. It was time and money very well spent.


We had been living in the house for over 6 years and had long wanted to upgrade the outdoor areas and make a better connection to the pool.  The large block offered significant potential but the sloping terrain presented a number of challenges and it was clear we needed professional architectural support to both tackle the practical issues and deliver a high-end design finish.

The services provided by Dion Seminara and his team were comprehensive helping to steer us through concept design to tendering, procurement and construction management.  Without this support, we would have been exposed to significant risks and doubtless additional costs. We are very happy with the finished product which has significantly enhanced our living space delivering a finished product that was far beyond what we had anticipated.

Neil & Hazel

I would like to say that I really appreciated your comments when we spoke last year regarding a possible renovation. You gave your opinions and time without obligation and it really helped me in my decision making. I’ve since seen your TV segment that you did and read the updates that your company has sent through.

I can safely say that if I was to ever reconsider a renovation or build, or if a friend asked me for a recommendation, I would certainly consider you first. When I called you last year to enquire about renovating, your comments were open and honest and extremely helpful. No one else I called took the time to really talk to me about the process. You were honest and genuine… qualities that are hard to find these days!

Thanks and all the best for the future.

Sherwood, Brisbane

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!

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 our Brisbane architects today for a design consultation.

Your Brisbane Architects.

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

As a Brisbane architect, we 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 as your Brisbane architect 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 principle, Dion, about your new future home or commercial architect Brisbane project.
