In pictures: Life in an eco-roundhouse

Built inside Pembrokeshire Coast National Park, with agreement from the owners of the land, the roundhouse – which cost £3,000 to build - does not have planning permission.

The threat of demolition has been hanging over it since officials spotted it from the air in 1999.

Tony and Jane’s campaign to remain has won many reprieves and delays, but the park authorities are due, yet again, to make a decision about its future in the next couple of months.
