To celebrate the recent launch of our US product catalog, ArchDaily Materials, we've coupled six iconic architects with what we deem to be their favourite or most frequently used material. From Oscar Neimeyer's sinuous use of concrete to Kengo Kuma's innovative use of wood, which materials define some of the world's best known architects?

To celebrate the recent launch of ArchDaily Materials we've brought together five projects with fantastic façades, from Viñoly's Dolby Regeneration Medicine Building in San Francisco to Holzer Kobler's PALÄON in Schöningen, Germany. A building's envelope is often people's first impression and, in recent years, have been one of the focuses of innovation in the design and construction industry. The projects we've collated show a glimpse at what's possible with façades and wall finishings.

The RIBA's recent report "City Health Check: How Design Can Save Lives and Money" looks at the relationship between city planning and public health, surveying the UK's 9 largest cities in a bid to improve public health and thereby save money for the National Health Service. The report includes useful information for city planners, such as the idea that in general, it is quality and not quantity of public space that is the biggest factor when it comes to encouraging people to walk instead of taking transport.

The following 20 articles are what we at ArchDaily consider the Best of 2013. They may not have received the most traffic, but they posed fascinating theories about the state of architecture and urbanism today, they gave us insight into the creative processes of innovative architects (from Bjarke Ingels to Peter Zumthor) and, most of all, they provoked us to question: What does architecture mean? For us architects, and for the world?

It's that time of year again! The time when we round-up what you, our dear readers, most enjoyed this year. The following ten articles - from fun lists (30 Architecture Docs to Watch in 2013) to thought-provoking looks into the state of the architecture profession (Are Renderings Bad for Architecture?) - caught your attentions and provoked some great comments. See them all - including our record-breaking #1 article - after the break.

The American Institute of Architects (AIA) and MIT’s Center for Advanced Urbanism has produced a new report examining urban health in eight of the USA’s largest cities, which has been translated into a collection of meaningful findings for architects, designers, and urban planners. With more than half of the world’s population living in urban areas - a statistic which is projected to grow to 70% by 2050 - the report hinges around the theory that “massive urbanization can negatively affect human and environmental health in unique ways” and that, in many cases, these affects can be addressed by architects and designers by the way we create within and build upon our cities.
