Bye bye Theory

Somehow this past weekend I browsed past John Hedjuk's "Bye House". I was never a particular fan of Hedjuk, I love the drawings and I recognize the importance of that streak of the avant garde, especially in the historical context bla bla bla. What I had not realized was that the Bye House had gotten built, and though it does look somehow fun, I think I lost something there. Should one build theory? Paper architecture in concrete? maybe better left to paper I think, though of course this is no vote.
