This study documents an innovative experiment in participatory urban visioning conducted in Mae Hia Town, Thailand. The workshop utilized LEGO® Serious Play® (LSP) methodology integrated with Imaginary Future Generations (IFG) techniques to enable diverse stakeholders to articulate their personal and collective urban imaginaries in tangible forms. Forty participants representing five key stakeholder sectors collaboratively envisioned Mae Hia's past (2014), present (2024), and desired future (2044) states. The findings suggest that LSP can serve as policy instruments for activating civic agency, co-producing knowledge, and embedding context-sensitive planning capacities in secondary cities. This approach offers valuable insights for urban planners working in contexts where traditional engagement methods struggle to foster meaningful dialogue across diverse groups and generations of residents.
