I found this Chilean architect through Dezeen. I'm very impressed with the play of light and shadows produced in this particular house... However, when reading through Irarrazaval's website, I was most impressed and intrigued with his news section. Many architects maintain a news section as a list of links to recent publications, however Irarrazaval's news is actually a link to his blog (which as we all know can truly be kept up to date). Its a very clever and forward thinking move for an established architecture firm.
