A startup is helping solve one of San Francisco's problems with shipping containers.

Campsyte is turning these steel boxes into uber-cool work spaces, and then parking them on vacant lots. While it might take years to build an office (think permit process and then actual construction), you can easily throw together a workplace with these cheap, sustainable building blocks.

"​Today even an office tenant improvement project costs $100 per square foot," Campsyte co-founder and CMO Allen Wong said. "Campsyte builds modular and prefab structures that can actually be relocated. Campsyte ​ passes those ​ savings to our tenants by reducing their ramp-up time."...

Wong said there are thousands of empty lots around the city and owners often can't afford to build on them. With their unique land-sharing model, Campsyte can work with these lot owners to determine options and create interim office spaces that can quickly and easily be rented. With this model, Wong thinks sleep areas of the city could turn into vibrant communities.
