Until recently,we have always had to think about everything we want our house to do. if we have wanted it to be warmer or cooler, lighter or darker, we have had to turn the heating or lighting on or off. However, for some families already living in intelligent houses, daily life has changed in many ways. they don't worry about turning off the light or locking the door before they go out. the house does all this for them. Families in intelligent house don't have to do as much work to keep their home clean and comfortable - and the hi-tech kitchen means it isn't difficult to prepare family meals.
