Boulders can be used to create a maze, seating, or as stepping stones. The spiral arrangement of boulders below defines a space that can be used by teenagers as their territory. A boulder terrace set into a sloping bank can be a simple and effective way of creating a climbing wall.

How to build

  • Set boulders within a meadow or glade to the side of a footpath. Long grass and tall meadow flowers may grow up around. Make up ground within spiral with compacted stone.
  • Approximately 1/3 of the boulder should be buried for stability. Boulders should be butted together as closely as possible with shapes to suit and placed so that a flat top is created at suitable height for seating. Significant gaps should be pointed with mortar mixed and coloured to match boulders to prevent foot traps. Slight differences in height between boulders is alright.

Useful contacts

  • Use local stone if possible, suitable boulders previously purchased from
  • Refer to fall heights, falling space and entrapment in safety section of appendix.
  • CDM regulations might apply for engineering works.
