I truly believe that there is no project, however simple and basic it may be, that doesn’t lend itself to optional and different outcomes….so, even if there may not be zoning or building code issues, the very nature of the design process can suggest options (i.e. if you are only changing a door…what kind of door? what kind of hardware? Pros and cons of different doors…doors with glass or with/out?…cost implications of one versus another, you see?) – Even if you know they are going to hire you, show professionalism and true intent in making the experience the best possible for both…and yes, absolutely, this is the best testing ground for the full working relationship ahead of you.
