When I travel into London on the train, I often count how many trampolines I see in the gardens that the railway line travels by, just to pass the time. It always surprises me !!!
We carry out designs for lots of family gardens and are often asked to include the obligatory TRAMPOLINE.
For low cost options we position them within borders, sometimes behind hedges, which I like as you can see the children jumping up and down but don't see the ugly trampoline, sometimes with secret paths which children love.
Another alternative is to sink the trampoline and here we have installed a trampoline designed in amongst rubber bark mulch and interplanted with Fatsia japonica and Ferns.
