So the last bit of electrical work is to install the 16mm² cable through to the car park and main road connection. It is the cable on the large wooden bobbin. Also to install the power and switch cables for the fountain, garden lights, BBQ area and Car Park so they can all be controlled from the house as well as locally.
There is so much stone that I am now starting to bury it over the warning tape to give an additional layer of protection from future digging activities. It also helps to hold the tape in place as I backfill.
