Some photos of the actual build.
A few videos of the groundwork
The concrete lorry was more than 80 meters from the base so we had to get it pumped to save waling hundreds of wheelbarrows full of wet concrete up the hill. The video shows how they clean the pipes out, the send a ball down the pipes under extreme pressure from clean water that follows.
This is Steve (our digger driver) who had the hard job of digging out the base for the concrete base, digging a trench all the way back to the house for the electric cable and water pipe.
This video shows him digging out for the gully drain to get rid of the rain water off the patio.
