My design approach is to beautifully wrap function into the aesthetics which, is especially important in commercial spaces where function is by far the most important aspect of a design.  If a space does not function well, no matter how beautiful, the design is a failure.  However, if each and every detail is well planned and thought through with the end user in mind, the space will only require minimal updates through its lifetime.  In addition, a great commercial design will promote its occupants to be productive, creative, constructive, and professional.
