Bespoke Brisbane Architects,
Interior Designers and Landscape Designers

Specialist Home Design Architects
Individual designs expertly tailored to YOUR specific needs and our sub tropical climate

Our Principal Architect Dion has been an architect in Brisbane for over 30 years,
and is strongly focussed on a humanist approach to working with people that sets us apart from alternatives.

We will reinvent the way you feel in your space as our pre-design processes are designed to collect your unique design aspirations and needs.
By prioritising what activities are important to you, and how you plan to use your home both now and in the future,
we create room to room functionality and a dream home that will serve you for a lifetime.

Brisbane’s sub-tropical climate, vernacular character to contemporary housing types; our irregular shapes of land and topography of our sites, pose unique design challenges. As a specialist home design architect, climate responsive design producing naturally comfortable living environments and functional, aesthetically pleasing spaces is our paramount objective.

As we are often also your interior designers and landscape designers, we work hard to ensure there is inside and outside flow between spaces;
interesting views and vistas from within, to and from the outside.

We have an extensive knowledge base of both interior and exterior materials for the best contextual feel and long-lasting outcomes, depending upon your budget constraints.

If you’re looking for a team of architects in Brisbane that care about your individuality, we can breathe life into your vision.

We’re here to help you realise what is going to work for you, whether that is just for advice, partial projects, or a turn-key solution.

You are almost home.

How we focus on your lifestyle and comfort

Queenslanders spend almost 90% of their time outdoors. So 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 consider many factors in our planning and design phases. So that we can achieve your definition of an enhanced lifestyle.

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

We inspire you. We listen to you

Sometimes it’s hard to know what you want until you see it.

Dion is skilled at asking the right questions to understand your needs. He can then illustrate inspirational ideas to achieve your goals.

During our pre-design services, we set out to identify what you’d like to change about your home.  We learn what your preferences are to truly enjoy comfortable living.

We are then able to consult on a range of ideas from existing house designs to bespoke solutions.

With over 30 years’ experience as an architect in Brisbane, Dion understands the needs of local housing. He is able to translate homeowner thoughts into inspiring designs. Designs that are suitable to the climate and surrounds.

While we’re more than capable of giving ideas, we are not here to make assumptions on how you should enjoy your space. Lifestyle needs are personal and we allow your architectural requirements to mirror this. Our transparent process is easy to understand. You will have no hesitations or difficulties in sharing your input or changes. Making sure your needs are heard every step of the way.
