The table below gives you a quick overview of the various types of consultants and sub-consultants usually involved in more complex projects.

This table is indicative only since the appointment of a professional and how that translates to the relationship with the Client is always project specific. For example, in one project the Landscape Architect could be directly appointed and paid by the Client (Developer) and be a consultant, whereas in another project he might be appointed by the Architect and therefore by considered to be a sub-consultant.
