The question

A built-environment team wanted to reflect critically on its work in the Lower Lea Valley, together and on foot. I needed to connect engineering history with questions of access and equity, and give a moving group a way to contribute within a two-hour session.

My contribution

I conceived, designed and built a five-stop route, a 15-page print companion and a mobile workshop interface. I paired engineering accounts with cited critical readings, and created tools for voting, notes, photographs and voice recordings. The app connects contributions to a shared display; local updates and a retry queue support interrupted connectivity. I developed the work through critique and delivered it collaboratively.

How I approached it

  1. Research the route

    I connected five stops to engineering history and cited questions about regeneration, access and equity.

  2. Make the companions

    I designed separate print and mobile experiences around shared content, including maps, readings and prompts.

  3. Support a shared reading

    I built arrival polls, field capture and a shared display to carry observations from the walk into the group discussion.

What exists

  • A live two-hour walking workshop delivered for a built-environment practice’s Cities and Infrastructure team.
  • A 15-page A4 companion and standalone vector route map, with PDF, SVG and PNG outputs.
  • A mobile companion with voting, field capture, shared display and local retry behaviour.
  • Cited critical readings and engineering references woven through the route, print and interface.

Where the work stands

The case presents my route, print and interface design. Delivery was collaborative; commissioner, co-host and participant contributions are not reproduced here. The live archive is not a public showcase.

Design choices and constraints
  • Use one arrival poll to connect the walk with the closing discussion.
  • Update contributions locally and queue retries for interrupted connectivity.
  • Share content between print and web while designing their layouts separately.
  • Distinguish engineering accounts, cited critical readings and open questions through typography.

A two-hour walk, a moving group and patchy connectivity required concise reading, quick interactions and a reliable print companion.
