8i Architects

We don't take shortcuts, we care deeply about what we do, and we want the process to be as painless and efficient as possible to get the best outcome for our client over the life of the asset.

8i Architects is a design based architectural practice specialising in innovative, functional, cost effective and sustainable design solutions underpinned by precise detailed documentation resulting in well regarded constructable development.

The firm was founded by Brisbane trained architects Hieu Nguyen and Charmaine Kai in 2005. 

Since then, 8i Architects has grown to include architectural technical support staff to enhance the practice’s ability to provide a comprehensive service to clients. 

Our focus is on design excellence and the creation of quality spaces that are unique to the site and the client. 

We strive to incorporate qualities of the context into the built design through innovative aesthetics and ESD (Environmentally Sustainable Development) principles.


We collaborate with our clients to achieve a creative design that is delivered on time and within the construction budget.

Innovative design implementation and management are integral from initial concepts through design development and documentation phase to client feedback of the outcome. 

Design management incorporates quality design solutions with control of cost, programme and delivery 

In the modern architectural setting we have retained the old school principles of being technically equipped to work with builders, provide a hands on experience, be dependable and easily contactable.


  • 8i Architects has the resources to undertake works with construction budgets up  to  $110 million.

  • We have a third party endorsed Quality Assurance System compliant with ISO 9001:2000.

  • We have a Queensland Government PQC Rating of Level 3 - Industry Best Practice.

I’ve worked with 8i for 10years. They have done half a dozen schools for us, the most recent an award winning $30 million school. I will only work with 8i in this space as they are like no other architecture firm. Charmaine and Hieu are low maintenance, which is so important when time is so precious. They understand the scope, they meet the timelines, they get it done, they make no mistakes. Whatever you ask of 8i they get it right!  


Sean Snowden, Estimating and Design Manager - McNab Builders 

Charmaine is incredibly practical, bright, organised and picks things up quickly. She always visits the facilities, understands what is needed to be in what space and the intricate workflow of the business. 8i do not give a template solution, they customise and personalise the service and outcome to make it work for the customer. Risks are thought of ahead of time and are addressed up front. Charmaine speaks the lingo of the other professionals and gains their respect really quickly! She drives collaboration, listens, educates and breaks things down in laymen’s terms! 8i have taught me the value of spending up front to always save in the end! 

Dr Adrianne Pope, IVF Specialist 

I have worked with Charmaine, Hieu and the team at 8i Architects for the past 6 years. I can honestly say that if you want no nonsense, non-ego based, well thought through and sensible architecture then let 8i manage your project for you. In my opinion 8i are big enough to handle projects up to the value of around $100m but small enough to provide the level of service that you won’t get from the larger architectural firms who will give your project to a junior architect to manage. There is only a hand full of Architects I would recommend in Brisbane and 8i are right up there.

Michael Page, University of Queensland

Hieu is an excellent communicator, he is proactive, good to work with, and calls a spade a spade! A lot of architect and design guys are the arty flowery types, just good at conceptualization. Hieu gives more than that, he can demonstrate how he is going to make it happen, which is why we look to work with him. 

Steve Watkins, Project Manager

Constructions Group has been working with 8i Architects for many years and have engaged them to undertake the design on many of our Design and Construct Projects. 8i are efficient and lateral thinking when it comes to resolving design issues and without compromising the integrity of the design are able to come up with cost effective solutions for our clients. We would highly recommend 8i Architects to design and construct contractors and developers alike.

Murray Creevey, Director - Constructions Group
