Bespoke Brisbane Architects bringing peace of mind and tailored solutions to your unique projects

Your Specialist Residential Architects in Brisbane


Welcome to Dion Seminara Architecture Brisbane

It’s exciting to think that we may soon be working together to create your dream renovation or upmarket new home design. I have more than 3 decades of experience as a specialist home design architect for bespoke projects. Bespoke means a design tailored to your needs (including lifestyle and style needs) and the needs of the site or your block of land. I see myself as not only a design professional but also an educator. As a specialist in residential design, I can educate on all that is associated to achieve your best design outcomes. I have completed 1000’s of our professional pre-design, design advice services over the years and over 700 design services. These services have achieved, for those I have encountered, creative but functional design solutions with honest and ethical input from me along the way. 

You are in safe hands, if you are willing to think laterally and invest in us.
As Walter Gropius (a famous architect) says, “The mind is like an umbrella, it’s most useful when it’s open.”

Ours is a collaborative approach, it’s all about working together to get you the very best outcome. We take the time to truly get to understand you and your needs. Our expertise and years of experience allows us to create outstanding, unique designs beyond your expectations. Using the latest in cutting edge technology to help explain ourselves; we can take you on a virtual tour of your project before a shovel of soil is turned.

Whether your project is a new home, or a renovation, you will be delighted with the final outcome. Together we can create a stunning, tailored design for your project. I’m looking forward to discussing your needs in person.

I’m here ready to answer any questions you may have.

How we focus on your lifestyle and comfort

Queenslanders spend almost 90% of their time outdoors. As our homes allow for leisure and exercise, rest, entertainment, dining and more. These spaces play a huge role in how we define the quality of time spent with friends, family, and ourselves.

We will give you good advice and recommendations. You will experience a diverse set of designs that meet your requirements.

Sustainable Architecture:

In this sustainable building approach any harmful environmental impacts are mitigated by:

  • prioritising efficiency
  • effective use of natural light and shade
  • Effective ventilation, layout and use of renewable materials.

Efficient insulation can reduce the need for energy consuming temperature control… especially in the harsh Queensland climate.

End to End Inclusions:

Our architectural process is likely the most holistic approach possible. Because of our expertise, from interior design to landscape design, we are able to match your needs to well-engineered ideas. This includes placement and positioning of entertaining additions such as:

  • Pools and spas, bbq areas, gyms and tennis courts
  • Efficient use of leisure and relaxation spaces like outdoor lounges
  • Theatre rooms and dens that consider privacy and sound-proofing

Architecture for Accessibility:

A holistic view of architecture is needed for people with accessible needs. Our designs keep this in mind. If you have movement restrictions we can design from the ground up at the beginning.

We measure access to all rooms and surfaces. This allows for space to move in and out of these areas easily, with as little compromise as possible.

We consider many factors in our planning
and design phases. So that we can achieve your
definition of an enhanced lifestyle.
