Orlando Bloom is building an eco-friendly house in the British countryside.The 'Pirates of the Caribbean' star decided to construct his own green home because he can't afford to buy a property in London.The actor complained to Britain's Daily Express newspaper: "I was trying to buy somewhere in London but couldn't afford it. It is not the actors making money, it is the boys in the City."However, the project has been a lot more time consuming and expensive than Orlando had anticipated. He said: "I wanted to make a green house, a place that felt safe and comfortable and out of the way."But building a house has been so stressful, it has taken double the budget - but I did make changes."The 30-year-old, who is a committed environmentalist, recently travelled to the Antarctic for environmental organisation Global Green to study the effects of global warming. Orlando explained: "I slept in a room the size of a bus shelter and shared a toilet and bathroom with 27 other dudes. It was the most surreal experience I have had in a long time."Meanwhile, Orlando has not ruled out getting naked when he makes his West End debut in David Storey's play 'In Celebration' this July.When asked if he would reveal all, he replied: "Hmmm, naked in London? There's nothing wrong with a little bit of nudity. I'm not sure I'll be getting all my bits and pieces out though."
