A great deal of agricultural activity and development is able to take place outside of the planning system such that planning permission is not always necessary. 

However, in some cases planning permission is required, particularly for large scale agricultural buildings, and in such cases an understanding of the most effective approach of securing planning approval will be essential if you are to ultimately meet your development needs.  Hughes Planning is able to offer advice about when planning permission is (and is not) required for agricultural development and to assist you through the development process.
