When remodeling a kitchen, there are a variety of professionals you can hire. Once such professional is an architect. If you plan significant structural changes to your kitche--such as tearing out walls--an architect may be a good choice. However, choose one that has residential experience versus commercial experience unless he or she has designed restaurant kitchens. Keep in mind, your kitchen is a room where you spend much time.
Hiring the right architect is key. The letters AIA after a particular architect's name indicate that person is a member of the American Institute of Architects, a national association with some local chapters that may refer architects to you. Architects are specially skilled in major construction and will give you options if tearing out areas are not allowable due to the structure of your house. An architect may refer you to a kitchen contractor but always check that company out yourself.
Architects will likely have much experience with contractors they can trust but you should still do your due diligence. If an architect refuses to do business with a contractor you prefer, you may want to find another to handle the job.
