Some architects, such as John Lautner, never really did anything other than houses. His entire portfolio is basically residential. There's nothing wrong with that.
I paint daily with watercolors on 5-by-7-inch pads that are small enough for me to take them everywhere.
Frank Lloyd Wright made houses right up until the end. I think that's important because it gives you a direct connection to all the basic aspects of architecture - the spatial energy of the place, the construction, the materials, the site, the detail.
I'm sorry to say, but 85% of so-called 'green' firms make some of the ugliest buildings that were ever made. So for God's sake, I don't want to be categorized with them.
