The bench at Shirehampton was made with a group of local people of various ages at the end of 2013 and installed in January 2014. Here's how it looks after the first year:
The next bench was up in Leigh Woods, on the protected area of Stokeleigh Camp iron-age hill fort. It was made and installed in 2009 and did have some finishing (tung) oil applied at first. The five years since then have allowed mosses and other plants to move onto it and I think that it now looks part of the landscape in a pleasing way.
