(28)National regulations in the field of architecture and on access to and the pursuit of the professional activities of an architect vary widely in scope. In most Member States, activities in the field of architecture are pursued, de jure or de facto, by persons bearing the title of architect alone or accompanied by another title, without those persons having a monopoly on the pursuit of such activities, unless there are legislative provisions to the contrary. These activities, or some of them, may also be pursued by other professionals, in particular by engineers who have undergone special training in the field of construction or the art of building. With a view to simplifying this Directive, reference should be made to the concept of ‘architect’ in order to delimit the scope of the provisions relating to the automatic recognition of the qualifications in the field of architecture, without prejudice to the special features of the national regulations governing those activities.
