Cyril Dick’s house is neither a modern house nor a house of the future. It is 40 years old. There are more houses like that in the south of France. They are called “bubble houses”, and you can see why!

Cyril Dick is a designer and he loves round things. He collects old records and clocks. He also collects round furniture. And now he has a completely round house.

Everything in the “bubble house” is round. The centre of the house is one very big bubble. This is both the living room and dining room. There are round armchairs, a round table, and a big round rug(地毯) in front of a round fireplace. Around the living room are three small bubbles. One bubble is a kitchen with round shelves, another bubble is the garden room, and the third bubble is a music room. Upstairs there are two more bubbles—a bedroom and a bathroom.

The doors and windows are also round, of course. The window are like eyes. There aren’t any curtains(窗帘) in the house, because Cyril likes to see the garden all the time.

Bubble houses are the idea of a Hungarian architect(建筑师), Antti Lovag. “A lot of modern houses are bad for us, especially tall buildings of flats,” says Lovag. “Because round homes are more natural, people feel happy in them.” Cyril agrees with this. “Some people think my house is funny,” he says, “but for me, this is the perfect home.”
