John Fisher, a builder, and his wife Elizabeth wanted more living space, so they left their small flat for an old 40-meter-high castle tower. They have spent five years turning it into a beautiful home with six floors, winning three architectural prizes. "I love the space, and being private," Elizabeth says. "You feel separated from the world. If I am in the kitchen, which is 25 meters above the ground floor, and the doorbell rings, I don't have to answer it because visitors can't see I am in!" There are 142 steps to the top so if I go up and down five or six times a day, it's very good exercise! But having to carry heavy things to the top is terrible, so I never buy more than two bags of shopping from the supermarket at a time. Except for that, it's a brilliant place to live. "When we first saw the place, I asked my father's advice about buying it, because we couldn't decide. After paying for it, we were a bit worried because it looked awful. But we really loved it, and knew how we wanted it to look." "Living here can be difficult--yesterday I climbed a four-meter ladder to clean the windows. But when you stand on the roof you can see all the way out to the sea on a clear day, and that's a wonderful experience. I am really glad we moved. " What is the writer trying to do in the text?
