Detailed design

Work with the community to create a detailed infrastructure design


This stage will build on the activities already undertaken, and draw from the findings of the requirement capture and options evaluation stages to influence the shape of the process and define the objectives. A third workshop may be the most appropriate way to include stakeholders.

Create and gather technical tools that can be used to engage community residents eg the rainwater harvesting (RWH) calculator

Prototype systems may also be a useful tool for community participants to see how they work in action and apply that knowledge to design.

More information and examples are available in the Workshop 3 tool and requirement capture stage to support the successful delivery of a workshop. 

Encouraging active participation 

This stage has the potential to be ‘hands on’ and use a range of practical tools and approaches, the following are suggestions for the practical delivery and recording of activities

  • Using a mix of documenting activities that might include audio and video recording in line with the evaluation approach.  
  • Beginning with an overview of the co-design process so far, including the results of stage 1 – characterising the communitiesstage 2 – requirement capture, and stage 3 – options evaluation and a recap of the co-design process poster.  
  • Introducing key infrastructure technology that will be involved in the delivery of the project (for example, the rainwater harvesting information sheet
  • Use available and/or bespoke tools (such as the rainwater harvesting calculator) and hypothetical scenarios to develop solutions 
  • If possible, include a physical walk-around tour to identify locations within the community that solutions can be deployed and visit any prototype installations. This can be supported with documentation materials such as local area maps and note taking templates 
  • Further use of tools to develop specific design specifications, allowing community stakeholders to understand parameters and justify their recommendations 
  • A final plenary discussion to create consensus on the design outcome and identify how it will be taken forward 
  • Closing feedback such as a questionnaire for participants. 


This method should be applied with the involvement of community residents in the co-design process.  

Detailed information on how to get community residents involved can be found in stage 1 – characterising the community and the example in the Community Engagement Methods for Step 2


This stage generates project documentation and team reflections that should be used to evaluate the workshop.  

This stage will also generate participant feedback on the whole project if an evaluation questionnaire is used. The results of the questionnaire, in conjunction with other data, documentation and observations from the project, can be used to carry out a systematic evaluation of the project overall. The evaluation principles and processes are detailed in stage 5.
