About

Spectra

We believe citymaking needs a space for collective dreaming and building that helps people reclaim agency and redefine the design process.

What if there was a way to play with the big problems of the future that didn’t leave us feeling paralyzed and voiceless? Spectra is a growing community of Virtual Citymakers: real-life architects, engineers, and urbanists as well as virtual modders, creators, and worldbuilders. Our dream is to build a city for the future. In order to make it happen, we’re launching Spectra Cities to open a possibility space: a cooperative, digital playground for mixed-reality citymakers to hone their skills and forge the disciplines that will build this century’s most ambitious urban projects. 

We believe cities are complex and dynamic participatory processes that can only be built collectively.
