I bought this little gazebo in the Christmas section of my local Dollar Tree. It's a nice little resin piece that is part of their Cobblestone Corners set and wasn't loaded with Christmas decorations and could be easily converted to 15/20mm gaming terrain. The roof was simply glued on, so I was able to make it removable by cutting it with a razor saw (as well as removing the upper portion).
A quick repainting and some static grass and it was ready for gaming. The gazebo fits a small FOW base perfectly!
