At last the "smart" house is a reality. At least if you want to live in Watford, in Hertfordshire. There, a new development of 10 detached five-bedroom houses is being sold, complete with £25,000 sterling worth of Internet technology that will allow the owners to control their home from a distance. You can switch on the kettle in the kitchen from another room, or view a sleeping baby from another part of the world. The heating, lighting and security systems can all be activated from outside the house and if you need to stock up on food and drink, you can do it over the Net after using a scanner that tells you how much food is in the house. Four houses have already been sold at £500,000 sterling each.
