Recently I've found myself drawn to steel framed windows. Sort of old world European, or modern industrial look. I'd like the entire sunroom to be constructed of this style windows. Also the front entrance and certain interior walls and doors.
Sky Garden House by Guz Architects. Wierd, but I think it would be really nice to inhabit. It's also an interesting application of green roofs/roof gardens to a very modern, otherwise steel and concrete design.
