Bugger, an epic oversite by the look of things
I think the builder has trenched the conduit for the phone, but from what I read from a quick search, they won't do a pre-wire from the pit to connection point with the trench backfilled.
The wire down the external wall in the garage shouldn't be a problem, if I want a point on an external wall (like in the display home) they will struggle with the wall insulation.
Could have all been prevented with a quick call from the SS
Not that I had plans to run a home phone immeadiatly, but it would have been a lot easier.
