Concerns over second homes are certainly not confined to Pembrokeshire or Wales, but there are few better illustrations of the problem than the village of Solfach (or Solva in English), in Pembrokeshire.
Here around a third of properties are second homes and even on a sunny day in June much of the village is remarkably quiet.
On Prendergast, a picturesque road which runs alongside the River Solva there are now 31 houses, but fewer than a third of those are permanent residents.
Knocking on the doors of the last ten houses on the road, only one was occupied - by a couple on holiday for the week.
