6. Outdoor screens, Virginia Tech School of Architecture and DesignThe students at Virginia Tech's School of Architecture and Design had an impressive display of privacy screens as part of their Lumenhaus project.These screens are presented as a solution to urban housing, as living in a city can mean sacrificing privacy and outdoor space. They're designed to slide back and forth across an outdoor balcony, and help differentiate and privatize outdoor space as well as insulate and block or let in light as needed. The individual "petals" of the screens can be adjusted to completely close or open.
