There are a number of organisations that can help with both ideas and technicalities. Some of these specifically address the front garden as a subject in its own right. Others deal with issues that affect front gardens, the elements that go to make them up, their relationship to the public realm, their impact on the environment and how they are used, but are not specifically focused on front gardens.
Some organisations, particularly government departments and local planning authorities, are regulatory. Others represent interest groups or particular professions, skills and activities. The best initial approach to these organisations and to tap into what they have on offer is online. You can find links to a number of these organisations on our links page.
