SponCon is the nittiest, grittiest, smashin-est, bashin-est, clangin-est, bangin-est, creativist, barbaloot savin-est party in town!


Designed to inspire a culture of reuse with a free, engaging community activity, Spontaneous Construction, or “SponCon” for short, has become an annual Missoula tradition. Contest participants have seven hours to use their choice of Home ReSource materials to build the most beautiful, functional, and creative pieces they can dream up.

The event also features a variety of enjoyable, inventive reuse activities for all ages, music, and access to local food vendors for contestants and spectators alike. The contest draws teams of artists, DIYers, and builders to create works of art and utility, as well as a crowd of onlookers just there for the fun. After the judges announce winners, some pieces are auctioned on site, and top-judged creations go to the Benefit Auction.


Compete in the 7 hour building competition! Do you have what it takes to make an amazing upcycled masterpiece? Of course you do! Even if you don’t, you’re still going to have a ton of fun trying! Register your pro or general team while there is still space and let the games begin.

Participants receive a commemorative SponCon t-shirt, free breakfast treats & coffee, and one drink ticket. Plus, every team gets a prize!
