Charrette Method
Also known as: Design Charrette, NCI Charrette, Dynamic Planning Charrette, Collaborative Design Workshop
A charrette is an intensive, time-compressed collaborative workshop in which designers, planners, officials, and the public work together over several days to produce a feasible plan or design for a place. Codified by the National Charrette Institute in The Charrette Handbook, the method replaces the slow, adversarial sequence of separate meetings with short, repeated feedback loops in which designs are drawn, shown to stakeholders, critiqued, and immediately revised. Its purpose is to compress months of back-and-forth into a few days and to build shared ownership of the outcome.
Key highlights
- Compresses months of sequential meetings into days, accelerating a plan toward decision and adoption.
- Short, repeated feedback loops catch flawed ideas early and produce technically and politically tested designs.
- Co-designing in the open builds trust and shared ownership, reducing later opposition.
- Brings disciplines and stakeholders into one room so trade-offs are negotiated as the design forms.

When to use it
Use a charrette when a complex place-based project needs buy-in from many stakeholders quickly and when bringing decision-makers, experts, and the public into the same room can break a logjam — typical for neighborhood plans, corridor and downtown redesigns, campus or master plans, and form-based codes. It works best when there is genuine intent to act on the result and authority to make decisions is present. It is less appropriate when there is no real decision to make, when key stakeholders cannot attend the intensive days, when the timeline or budget cannot support thorough preparation, or when the conflict is so entrenched that mediation must precede design.
Strengths & limitations
- Compresses months of sequential meetings into days, accelerating a plan toward decision and adoption.
- Short, repeated feedback loops catch flawed ideas early and produce technically and politically tested designs.
- Co-designing in the open builds trust and shared ownership, reducing later opposition.
- Brings disciplines and stakeholders into one room so trade-offs are negotiated as the design forms.
- Heavily dependent on extensive, costly preparation; an under-prepared charrette tends to fail.
- The intensive multi-day format excludes people who cannot take time off to attend.
- Loud or organized voices can dominate the room unless facilitation is skilled and deliberate.
- Momentum and consensus can fade if there is weak follow-through after the event.

Frequently asked
How long does a charrette last?
A full NCI-style charrette typically runs as a continuous four-to-seven-day collaborative work session, long enough to fit several complete feedback loops of design, public review, and revision. But the event is only the middle phase: substantial preparation precedes it and implementation follows. Shorter one- or two-day 'mini-charrettes' exist for narrower questions, though they trade away some of the iteration that makes the full method powerful.
What makes a charrette different from an ordinary public meeting?
An ordinary meeting usually presents a finished proposal for comment, with revisions, if any, happening out of sight over weeks. A charrette designs in the open and in real time: the team produces work, shows it, hears reactions, and redraws within hours or a day, repeatedly. That tight feedback loop means participants watch their input reshape the plan, which builds trust and yields a design that has already been tested against public, technical, and political reality.
Why is preparation considered so important?
Because the intensive days leave no slack. During the charrette the team must design, test, and revise under deadline, so any missing baseline data, unidentified stakeholder, or unclear decision authority becomes a crippling gap that cannot be filled in time. The Charrette Handbook treats preparation — assembling site, market, and policy data, engaging stakeholders, and setting up the workspace and schedule — as the single strongest predictor of whether the charrette produces an implementable result.
