Been a little busy with one thing and another (including the day job!)
Seen the electrician and we have decided a suitable strategy to get the wiring complete.
More importantly, Andy (who built the slab and did the groundworks) has returned to install the plumbing and guttering.
I’ve made a start on the data wiring – got a busy couple of weeks ahead – but nights are starting to get lighter, and I’ve got temporary power (so I can have light and heat whilst I work).
