The Trelowarren estate in Cornwall is famous for its sustainable holiday homes, but you don't have to be a greenie to find this place stylish. It's all very luxurious and that includes the pool. From March to October it's heated to 28C degrees by a carbon-neutral heating system and it's lined with river pebbles. If you get bored of the pebbles, lounge on a deckchair and enjoy a glass of wine from the New Yard Restaurant while feeling far, far away from city-life and stress.
