Fire Safety Is Designed Long Before It Is Engineered
Fire safety is often treated as a technical layer, something applied once the architecture is fixed. By that point, the most important decisions have already been made.
The reality is simpler, and more uncomfortable. The effectiveness of fire safety in a building is largely determined at concept stage. Not through calculations or reports, but through geometry, layout, and intent. In other words, through architecture.
The width and clarity of escape routes, the number and position of stairs, the relationship between compartments, the treatment of voids and facades, the accessibility of fire service intervention. These are not engineering add-ons. They are spatial decisions. Once fixed, they are rarely improved without disproportionate cost or compromise.
Where schemes work well, it is usually because fire safety has been quietly resolved before it becomes a problem. Travel distances feel natural. Wayfinding is intuitive. Compartmentation aligns with function. The building supports safe behaviour without relying on layers of technical justification.
Where schemes struggle, the opposite is true. Long dead ends are rationalised. Stairs are reduced or displaced. Open connections are introduced without a clear strategy. The design intent and the fire strategy begin to diverge, and the project becomes reliant on mitigation. More systems. More reports. More complexity.
This is not a criticism of ambition. Good architecture often involves openness, connectivity, and flexibility. But these qualities need to be balanced with an understanding of how fire behaves and how people respond to it. That balance is not something that can be retrofitted.
Architects are uniquely placed to get this right. They control the moves that matter most. A well-positioned stair can remove the need for compensatory measures. A modest adjustment to layout can transform escape strategy. Early decisions about structure and materials can avoid difficult conversations later.
This is where the conversation needs to shift. Fire safety should not be seen as a constraint imposed on design, but as a design parameter in its own right. When it is engaged with early, it tends to enable rather than restrict.
In my role as a Visiting Professor at Loughborough University, I see a strong appetite among architecture students to engage with these issues. When fire safety is introduced as part of the design process, rather than as a compliance exercise, the response is thoughtful and often innovative. The next generation is ready to do this better. The industry needs to meet that ambition.
There is also a professional responsibility here. Too often, fire strategy is expected to resolve problems that originate in the design. That expectation is misplaced. Engineering can optimise, justify, and sometimes compensate. It cannot fundamentally rewrite a poor spatial strategy.
The most effective fire safety solutions are usually the least visible. They sit within the architecture, not alongside it.
The message is straightforward. If fire safety is considered late, it becomes a problem to solve. If it is considered early, it becomes part of good design.
