I had a professor say to me once that an entrance isn't merely a door. I hadn't really thought about it before, but looking at many of the great buildings that I admired the entrance door was not a prominent feature. The entrance, instead was more implicit in the design. This project by Archinauten Dworschak + Mühlbachler ZT Gmbh is a great example of how the architecture invites you in naturally as part of a greater scheme. Instead of simply puncturing the facade with an opening, the whole building opens to invite you inside. Probably not possible in every case, but the entrance is often the most prominent part of the design, so it deserves a little more consideration.
