The porch foundations were a bit more complicated than the main tree house. The porch is supported by what I may call an inverted 3D roof truss which spans between two tree stumps. Below you can see Didymus balancing on the mid point of the truss (temporarily supported at each end).
To make matters more interesting you can see that the last tree stump (on the right – below) was way too short.
Thus we used an “Alpine” style cross made of simbi (metal) by Soko. This anchored the centre of the truss firmly into the tree stump with the help of some cement. So technically the tree house still doesn’t touch the ground (yet) – it just has a steel-cement support in one tree stump.
(Just in time for the phantom rainy season – its a drought year)
