The Klong Toey Community Lantern — a community space in the oldest and largest of Bangkok’s slums — was built very quickly. Not quite as quickly as shown in this three-minute timelapse video, but construction for the project took just three weeks thanks to the help of the community.

But while construction went fast, Norwegian architects Yashar Hanstad and Andreas Gjertsen — of the firm TYIN tegnestue Architects – took six months to design the space. They conducted interviews with Klong Toey residents and held public workshops to find out exactly what the 140,000 person community — which struggles with rampant unemployment, drug use and substandard housing — needed. The goal was to create a safe oasis for community members of all ages to play and congregate.
