While house owners have quite a lot of freedom in how they plan and what they do in their front gardens, as with other aspects of property and land, there are issues that are subject to central government or local government control. Laws and rules applicable to the front garden are mostly administered through the Town and Country Planning Acts and associated legislation.
Some local authorities take a close interest in front gardens and in particular their use for car parking. Because of this, they sometimes publish recommendations and rules about this.
In addition to statutory controls, some houses are subject to covenants that were set up to maintain the quality and consistency of front gardens in a street. Such covenants are most likely where the house is a part of an estate, often developed comprehensively and with the objective of maintaining character and quality of environment in the street.
