Last summer while visiting my sister in Utrecht, we built a 2×4 bench. We used the wood that was available in the local store. However, the wood was of different dimensions and it cost a lot more too.
So this year we decided that it would be easier to make a chair here in Seattle out of actual 2×4’s. After building one, and taking it apart again, it appeared to fit perfectly into a suitcase.
On the picture you can see how it fits nicely in the Dutch patio, also notice the bench in the back ground.
