_____, “For me, it’s absolutely easy to say what my idea of a perfect house is. I’ve been dreaming about it since my childhood. I was brought up in such a house. My house should be my home, first of all. I mean it should be the place where I feel comfortable and welcome. I dream about a cosy house in the centre of a small quiet town, not very big but large enough for me and my family. I think it should have three bedrooms, a kitchen, a sitting room, and a big dining room with a large table. I like to entertain guests and to treat them to something tasty – that’s what I need a big dining room for. I would also like to have a small garden with flowers and fruit trees, with an arbour and some comfortable benches. There should also be a lawn and a play yard for children.”

_____, “Well, let me think… It should be large, first of all … a mansion, I think, somewhere in an isolated place, a two or three-storey building with a balcony, columns and things like that. It’s even better if it looks like a castle with towers and gates, and high walls. It’s so romantic! Plenty of rooms, staircases, an attic and a basement. It would be great if it was a real old house where ghosts live, like in fairy-tales. I could feel like a princess. But there should be all those modern conveniences like central heating, electricity, cold and hot water, gas, landline and Internet access.”

_____, “The house of my dream? Well, it would be a farm or ranch, I think. It’ll be situated near a forest, a river or a lake. You know, I like nature. The house should be a simple one, not very big, but with a large yard and fields around. I don’t need all the modern conveniences, for I won’t spend much time in there. I’d like to have some cottages or cabins also to have some rest when I get tired. There should be a garden to grow fruit and vegetables. But the main thing is the barnyard, to keep cows, sheep, horses, and pigs. I like animals and I like to take care of them.”
