At inTOTUM®, we believe good design goes beyond just looking the part - it needs to work. Whether we’re designing a retail fit out, planning a fuel system, or coordinating a full commercial build, we focus on practical solutions that make sense for the people using them.
We’re a team of designers who know how to navigate the details. From the early ideas through to construction and handover, we bring structure to the process, keeping things moving, keeping things clear, and making sure nothing gets missed.
Our work spans Building Design, Interior Design, and Underground Fuel System Design. We partner closely with developers, builders, tenants, and owners to deliver commercially driven design solutions while maintaining the quality required to secure approvals, attract tenants, and deliver long term asset value.
inTOTUM® started in 2012 with a clear vision, to create a design practice that values both people and process. Based in Brisbane, we work on projects all over Australia.
At our core, we value leadership, integrity, and clear communication. We take pride in being easy to work with, and we’re not afraid to take the lead when needed. We are a team who understands the big picture and takes care of the details along the way.
