The countdown is officially on, there are now just two weeks left to submit your entry for One Big Idea, and this is your moment to shape the future of the built environment.

If you’ve ever had a spark of inspiration… a “what if we tried this?” moment… or a fully formed strategy sitting in your notebook, this is your chance to bring it forward.

Why Your Idea Matters

The built environment sector is evolving rapidly, social expectations, sustainability goals, new technologies, and economic pressures are reshaping how places are planned, built, and experienced.

One Big Idea is designed to celebrate the creativity and curiosity that drive this sector forward. And your idea doesn’t need to be perfectly packaged or fully actionable. In fact:

Your submission can be anything from a tiny spark to a complete strategy. If it has the potential to advance the built environment, it’s welcome.

You’ll find examples, guidance, and plenty of food for thought.


So far, ideas have included:

  • Portals for private sector tenants
  • Developing standardised stakeholder engagement metrics
  • New anti-demolition schemes

These are fantastic, but there’s room for so much more. From digital innovation to sustainability to community engagement, anything that pushes the sector forward is fair game.
