Project brief
Define the conditions — site, program, ambition, constraints, stated plainly enough to build on.
AI-Guided Concept Design Engine
The quiet structure
behind strong concepts
Prefig carries an architectural concept from brief to final argument across ten disciplined stages — with every alternative preserved and every decision held to account.
“A concept is not a mood. It is a position — and a position must be defended, stage by stage, until it becomes a building.”
How it works
Ten stages. One argument.
Concept directions
Distinct positions emerge. You choose one; everything after answers to that choice.
Spatial strategy
Organise the idea: how space is arranged to serve the concept, not just the program.
Massing logic
Become a building — volume justified against the spatial logic already set.
Form & material
Define character: geometry and material argued together, not as finishing touches.
Narrative
State the argument in words, in parallel with the geometry.
Diagram strategy
Make logic visible — circulation, program, massing options rendered as legible diagrams.
Visual studies
Test atmosphere — how the space feels, not only how it is organised.
Precedents
Reference intelligence: sourced buildings that sharpen or challenge the position.
Final design argument
Prove the position — a concluding synthesis, not a rendering.
State, preserved
Every decision, alternative, and revision stays inside the project across all ten stages.
Consistency, enforced
A private evaluation lens checks each new stage against the concept’s established spatial logic.
Argument, not aesthetic
The end is a defensible position — not a mood board of images to like.
The Platform
Strategy made visible.
Decisions held to account.
Every stage produces structured output that feeds the next. Alternatives stay visible. Logic stays traceable. The final argument writes itself from frozen decisions.
- All alternatives preserved
- Logic tracked across stages
- Consistency checks at every gate
- Export-ready design argument
