Bespoke Design Architects,
Interior Designers and Landscape Designers

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 completely reinvent the way you feel in your space as our pre-design processes account for your unique 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 and tendency for unique blocks of land pose unique design challenges. So, we achieve natural temperature control and environmentally friendly spaces wherever possible and allow your building to conform to all limitations and opportunities perfectly. If you require holistic services, we also hold a builder’s license and have dedicated interior and landscape designers.

If you’re looking for a Brisbane architect that cares 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.

The “Client-First” Brisbane Architecture Firm

  • "We had long wanted to upgrade the outdoor areas but the sloping terrain presented a number of challenges. 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

  • "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. 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."

    Clio

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

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 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

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 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. 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 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.

Our Principal Architect, Dion Seminara, has over six years of University Education. He also has over 30 years of ongoing professional development. He is professionally obliged to advise you on all aspects of a building project.

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