There are over 22 million homes in Britain that come in various sizes, ages, and types, from old cottages to new buildings. Many British people prefer older houses, which are often more expensive than modern homes. Approximately two-thirds of British families own their own homes. The British also enjoy gardening, and gardens can be found everywhere ranging from small urban spaces to large country estates filled with flowers and trees. Some homes aim to live in harmony with nature, like hobbit houses that utilize natural materials and design to admit light and air.
