How we focus on your lifestyle and comfort

Queenslanders spend nearly 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 consider many factors in our planning and design phases to achieve your definition of an enhanced lifestyle, and you will experience a diverse set of recommendations and designs that meet your requirements. Sustainable Architecture: Also known as green building or eco-friendly architecture, in this design and sustainable building approach any harmful environmental impacts are mitigated by prioritising efficiency and effective use of natural light and shade, ventilation, layout and renewable materials. In the Queensland heat, a large factor includes efficient insulation to reduce the need for energy consuming temperature control.

End to End Inclusions: Our architectural process is likely the most holistic approach possible. With expertise from interior design to landscape design and everything in between we are able to match each hour and occasion of your time spent in the home to well-engineered ideas. This includes placement and positioning of entertaining additions such as pools, bbq areas, gyms and tennis courts, to efficient use of leisure and relaxation spaces from outdoor lounges, spas, to theatre rooms and dens that consider privacy and sound-proofing.

Architecture for Accessibility: Designing homes and renovations for accessibility or needs of those with any movement restrictions or disabilities requires a holistic review from the ground up at the beginning of the master plan. The architect measures access to all rooms and surfaces to allow for space to move in and out of these areas easily with as little compromise as possible.

We inspire you. We listen to you

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

A leading Principal Architect is skilled at asking the right questions to 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 and living experience, and learn which tastes and passions fuel your ability to truly enjoy comfortable living. With this information in mind, we are able to consult on a range of ideas from existing house designs to bespoke solutions.

With over 30 years’ experience translating homeowner and business owner thoughts into inspiring designs, we’re confident we can show you a space you never realised you loved already. See our Architectural Inspiration. 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 process from ideation to design and construction is incredibly transparent and easy to understand. You will have no hesitations or difficulties in sharing your input or changes to ensure your needs are heard every step of the way.

With over six years of University Education and ongoing Professional Development, your Principal Architect is professionally obliged to advise on all aspects of a building project.

  • We are 100% independent of builders and contractors
  • A competitive tender process ensures the best fit of contractors work on your project
  • Our design process allows for easy two-way communication and changes
