Intelligent" homes might look a little unusual from the outside. This is because the builders use a lot of glass and wood to make the walls. Some of the houses even have a grass roof because it's kinder to the atmosphere! But, inside, they are comfortable and bright. The technology, which is similar to that of your TV remote control, makes sure of this. There are always enough lights on in every room and the windows close when it starts to rain. The water is always at the correct temperature whenever you want to have a shower and the house doesn't allow you to use more water than you need. You can even watch television in every room, or use the close-circuit cameras to see what's happening in the garden.
