Properties with a garden are going to be on the more expensive end of the market. In rural areas detached and semi-detached houses will be more likely to have larger gardens whereas in more urban areas green pastures are harder to come by. Terraced housing might have a small patch of garden in the front or back of the property but the end terrace house may have a larger garden. There are strict planning laws and boundary laws around gardens. So to avoid any difficulties or neighborly contention be sure consult the title deeds.
