Just a random thought as to what standards there were for treehouses and playgrounds…not in the standard scope but could include a reference for clients since many have children and playgrounds. Here are some tips I found just for general knowledge…it appears there are standards for everything!
Any tips on what to say or not say for treehouses/playgrounds?
