It is the thrill of the hunt. The realization/materialization of ideas stirred up in your head and then formed with hands with care. It is proportion, scale, material and texture and craftsmanship coming together to make something that was not there before and something that in some way sings. I believe that architecture is a language that speaks to you as you make it and also as you later experience it. Firmness, commodity and delight? Seems simple enough.
