Definition
Concept design is the first stage after the brief: space planning, overall massing, orientation and the facade idea, shown in preliminary plans and simple views that are enough to decide on.
Why it matters on a project
Changing the idea at this stage is cheap; changing it after construction drawings is expensive, so the big decisions are made here.
Measurement and pricing
Usually a share of the full design fee and often the first payment stage.
Common mistake
Jumping into details and material choices before the space plan is approved.
Frequently asked questions
How many revision rounds are in concept design?
The contract sets them, usually two or three; extra rounds are charged separately.
Is concept design enough for a building permit?
Usually not; the permit needs more detailed architectural and structural drawings that meet municipal requirements.
