There is not single answer to this as it depends on what you can get in your
area and how you rate some of the risks. The cheapest option may not be the
safest. Many would not use CCA treated pine or creosote treated sleepers
where children play. Galvanised iron is also dodgy as it can have sharp
edges exposed. Non-treated timber that is durable in contact with the
ground is available in some places but it may be expensive. Used material
such as concrete blocks may an option, if you only need to go one block high
new blocks might be affordable. Try to get some local nursery/builder/
second-hand merchants on side to help.
