To save space, I'm growing my cucumbers up a tower (photo). I took 2 large wire tomato cages, turned one upside down (wire "legs" up). The other is on top, legs pointed down, the legs of the tower are sort of intertwined for stability, and zip-tied together. It is attached to iron rebar, hammered in the ground, for even more stability.
I have grown cucumbers like this before, they love to climb the tower. The base is a half meter in diameter, so you can easily grow a tower on one meter square. Two towers produce more than enough for us!
