In case you missed it, we're re-publishing this popular post for your material pleasure. Enjoy!

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 concept of the open plan revolutionized architecture  - promising light, space, and effortless collaboration (not to mention a more cost-effective way of getting lots of people into one space). Today, it's practically become a standard of design - but at what cost? 

A new report from researchers Jungsoo Kim and Richard de Dear, published in the Journal of Environmental Psychology, concludes that the open plan comes with some serious collateral damage - namely a lack of "sound privacy" - which outweighs its positive qualities. What's more, according to their results, the open plan doesn't even make a measurable improvement in communication at all.

Gensler, who recently topped out on the world's second tallest skyscraper in Shanghai, have just released a report outlining the keys to designing a successful workplace. Using their custom 'Workplace Performance Index' they surveyed 2035 office workers in the US to find out what makes employees happy and productive in their workplace.

One surprising result which they uncovered is that, in opposition to the trend of workplaces being designed to encourage collaboration, workers are actually spending more time on focused, individual tasks than they were 5 years ago. Consequently, over 50% of respondents said that they were distracted by others when they needed to focus. What's more, the survey found that when employees could not focus individually, collaborative work was also less productive.
