Nice looking design! Sorry for my curiosity, but what is the purpose of the fence and roof? I have found it useful in the past to add a small walkway down one side and a small ramp or steps to exit the foam pit. www.bikeparkitect.com
well i was afraid of falling out of the pit so i placed a fence there... And it is an outdoor pit thats why i've designed an removable roof that you put on at the end of the day.
well it depends on the funds. We've collected the money for the foam so far but for the tramp and material we still need a few months or sponsors. It will be centered in Ljubljana.
we've got the foam for free so the only expense is the wood and the tramp... tramp costs about 300e and for the wood lets say 400e.. none of these are exact but lets say a 1000 would do it
