Use an old door frame, an metal dining table base from the 70's and some re-claimed wood for the seating...very possible! Some shop time and a bit of dowel creativity, and bingo...a contemporary yard bench.
Yesterday we showed you a fold up desk. Here is a table for two that also essentially folds in on itself. In my humble opinion this is not as sleek as the wall mounted one, but it is still a good way to space save in a small area. What do you think of this one?
