The decreasing tendency of the amount of bees is a warning sign for human society. In our design, we tried to alleviate the harm for bees’ habitat in the cities through an efficient way that may cause less influences to people's daily life. Our design is about the frame that can be attached to different kinds of building facade and offers living resources to bees. With the frames, green spaces in cities will be connected. By giving the spaces that people rarely use from buildings back to nature, our design brings hope and makes the future TO BEE CONTINUED.
