9 years ago today, ArchDaily launched with a challenging mission: to provide inspiration, knowledge and tools to the architects tasked with designing for the 3 billion people that will move into cities in the next 40 years. Over these 9 years, as we have developed innovative approaches to help architects tackle the urban challenges facing our world, our work has brought us into contact with some of the most creative and respected architects in the world. To help us celebrate our 9th birthday, we asked 9 architects who are renowned for their creative and imaginative abilities to create drawings inspired by our logo, to show the world what ArchDaily means to them.
