The Premise 

Playgrounds are an environment that encourage exploration, creativity and new connections. Unfortunately, these places become harder to find as we get older, yet, our need for them hasn’t diminished. 


Welcome to OpenBuild

OpenBuild is a community focused environment that encourages participants to create, tinker, build and develop around an idea for a period of 24 hours. While OpenBuild has its roots in hackathons, our aim is to welcome those who are passionate about creating, regardless of their medium. LACUNA will be the home of OpenBuild.


 The Space

Housed in what was once the world's largest macaroni factory, LACUNA is bursting with murals, art installations and creative businesses. OpenBuild will take place at mulitple locations within the space and there's tons to see between 5 floors and 225,000 sqft.


The Outlet

As always, you have the option to work on whatever you'd like plus 4 challenges from Lacuna based companies. Redesign a creative space with a $2,500 budget, work on a live project with an international marketing and design agency, create new business strategy for Lacuna and work with iBeacons and Myo's.
