There used to be a guy who made the steps, but I doubt he does them any longer as he did not replay to repeated emails. I've refurbished one of these that was in great original shape. I had to make the steps out of hard board and square balsa. The hedge originally was made from Loofa. Its very hard to locate in very long lengths. I found a 6" one at a drug store and cut it with a single edged razor and used two pieces. The shrubs are just hard lichen shaped and glued on.
