Tony Wrench was toasting victory over the planners yesterday with a glass of wine made from the vines that grow on the turf roof of his wooden roundhouse. After ten years of planning battles, during which he and his partner, Jane Faith, faced having to demolish the home they had built themselves, they have finally won the right to stay. The roundhouse, known officially as “That Roundhouse”, was built in a hidden corner of a farm in the Pembrokeshire Coast National Park. It has a grass roof and walls built from cob – a combination of mud, straw, sand and water – and 16in (40cm) logs. A skylight was salvaged from an old coach and a milk churn is used as a stove.
