Classroom Design Is Not Interior Decoration
Classroom design is often reduced to furniture placement: where the tables go, where the shelves sit and what goes on the walls. But a classroom is an active part of the learning experience. It shapes what children can reach, where they can gather, how they move, what they notice and which activities become easy or difficult.
This is one of the central ideas behind the Brain-SET Environments Formula®, developed by Dr Kathryn Murray after more than 40 years in education. Brain-SET treats environment design as part of pedagogy. The question is not simply whether a room looks good. The question is what the environment makes possible.
What Does the Environment Teach Without Words?
Every room communicates. An open shelf can communicate that children are trusted to choose resources. A crowded walkway can communicate that movement is an inconvenience. A clearly defined collaborative area can make group work easier. A quiet corner can signal that taking time to reset is acceptable.
These messages are not the curriculum, but they influence the experience of the curriculum. Children are constantly interpreting the environment around them. Educators are doing the same.
This is why the idea sometimes described as the environment as a “third teacher” is useful. Reggio Emilia has long explored the relationship between environment, pedagogy, relationships and learning. Brain-SET builds on the broader insight that spaces are active participants in educational experience while placing its own emphasis on the developing brain and the conditions for Safety, Emotional connection and Thinking.
The Shift From “Where Should It Go?” to “What Does It Do?”
A more useful classroom design question is not “Where should we put this table?” but “What does this table allow children and educators to do?”
The same piece of furniture can support or obstruct learning depending on context. A low table might enable independent access for young children. In another setting it may create a bottleneck. A large group table may support collaboration, but it may also make it harder to provide quieter options. A display can inspire curiosity, but too many competing displays can add visual load.
Brain-SET encourages educators to move from static design decisions to purposeful environmental thinking.
Five Questions for Purposeful Classroom Design
When reviewing a classroom, start with five questions:
- What do children need to be able to do independently?
- Where can children connect with others?
- Where can they move, explore and use materials actively?
- Where can they engage in quieter or more focused experiences?
- How does the environment respond to different sensory, developmental and learning needs?
These questions are deliberately broader than furniture. They bring pedagogy, relationships and inclusion into the design conversation.
Calm Does Not Mean Silent
The aim is not to eliminate stimulation. It is to make stimulation purposeful and provide different ways for children to participate. A classroom may need spaces for energetic movement, collaborative play, focused work and quiet reflection.
Research from the Center on the Developing Child at Harvard University also highlights the importance of responsive relationships and safe, stable developmental environments in supporting children’s development.
This is particularly relevant when designing for neurodivergent learners. A single sensory profile cannot be assumed for every child. Flexible environments give educators more options to respond to individual needs.
The Classroom Is Also a Social Environment
Physical design is only one layer. The social environment matters too. Harvard’s research on serve-and-return interactions illustrates how responsive back-and-forth interactions between children and caring adults contribute to early development. Where educators position themselves can affect visibility and access. Where resources are placed can affect independence. How spaces are named can influence whether children understand what is expected.
NAEYC guidance on inclusive early childhood environments emphasises intentionally designing and adapting the physical, social and temporal environment around children’s diverse strengths, abilities and needs. That aligns with an important Brain-SET principle: environment decisions should be connected to the people using the space.
Design for Independence, Not Dependence
One of the strongest signs of a purposeful classroom is that children can do more for themselves. They can find resources. They know where materials belong. They can choose among meaningful options. They can move between activities without needing an adult to manage every transition.
Independence does not mean leaving children to manage everything alone. It means designing the environment so the environment itself supports participation. This is one reason prepared environments have remained influential across early childhood education.
Look at the Room Through the Child’s Eyes
Try a simple exercise with your team. Sit at a child’s eye level. Walk through the room slowly. Notice what is visible, what is reachable, what is hidden, what feels crowded and what feels inviting.
Then observe the room in use. Do children actually use the spaces in the way you intended? If not, resist the urge to blame the children. The mismatch may be telling you something about the design.
The Brain-SET Classroom Design Checklist can be used as a practical starting point for this type of review.
From Classroom Review to Professional Learning
The strongest environmental changes usually happen when educators are involved in the thinking. If someone simply redesigns a room for a team, the physical changes may be impressive but the underlying professional practice may not change.
Brain-SET therefore connects environment design with training, coaching and mentoring. Educators are supported to understand the principles, apply them to their own context, observe what happens and refine their decisions.

Classroom Design in Australia
For educators looking at classroom design in Australia, including schools and early childhood settings in Queensland and the Sunshine Coast, the practical question is not whether there is one ideal layout. There is not. The better question is whether the environment is purposeful for the particular children, educators, activities and context.
That is why Brain-SET does not prescribe one perfect room. It provides a framework for thinking.
What Happens When the Environment and Pedagogy Conflict?
Consider a classroom that values independence but stores the most interesting materials on high shelves. The teaching philosophy says children should make choices, while the environment requires them to ask an adult for access. Or consider a programme that values collaborative learning but provides only one large shared table. The pedagogical intention and the physical environment are working against each other.
These mismatches are easy to miss because educators become accustomed to the room. A design review can make them visible again.
The Environment Can Make Good Practice Easier
The most useful question is often: does the environment make the practice we value easier or harder? If educators value open-ended play, are materials accessible and varied enough to support it? If they value small-group interaction, are there spaces where small groups can work without competing with whole-group activity? If they value independence, can children understand where resources belong?
This is where classroom design becomes a professional practice issue. The physical environment can either reinforce the pedagogy or quietly undermine it.
A Review Does Not Always Mean a Renovation
Purposeful classroom design does not necessarily require a major budget. Sometimes the change is moving a resource, reducing competing visual information, redefining a pathway, changing where an educator sits or creating clearer choices. Other settings may require larger changes. The starting point should be the learning need, not the product catalogue.
Purposeful Design Supports Educator Wellbeing Too
The environment is experienced by educators as well as children. Storage, pathways, visibility, access to resources and the ability to move between groups can affect how manageable a day feels. Thoughtful classroom design can therefore support educator practice as well as children’s participation.
This broader view is important to Brain-SET because the aim is not to optimise a room for children while ignoring the adults responsible for teaching and caring within it.
Conclusion: The Environment Is Part of Teaching
A classroom teaches before an educator says a word. It communicates what is accessible, where people belong, how movement works, whether children can make choices and which behaviours the environment makes easier.
Seeing the environment as part of teaching changes the design conversation. Furniture still matters. Lighting, acoustics, resources and layout still matter. But they matter because of what they enable people to experience and do.
That is the deeper proposition behind Brain-SET: the environment is not simply where learning happens. It is part of how learning happens.
