Equestrian garden buildings - do they existing under permitted development?

In a word - No! The title above is an oxymoron. Most equestrian buildings for horses or horse related uses are not normally placed within the residential curtilage. Therefore any garden building placed outside the defined residential curtilage of the dwelling will not fall under permitted development.

It is only the residential curtilage of a dwelling that can utilise permitted development rights.

However, if you are lucky enough to own a property that has a large residential curtilage that happens to contain horse use as well or the garden building is placed within the residential garden but used for horse use then it can be classed as permitted development in my opinion.

Placing a garden building in an adjacent paddock is not permitted development.

Certain exemptions or loop holes do exist for some types of horse storm shelters where they are classed as temporary buildings on skids for example so that they can be easily relocated around the field or paddock. Most planners seem to turn away from pursuing any enforcement action on low level use of these types of equestrian shelters.
