SBLUG Iron Builder Challenge

The next round of the Southern Bricks LUG Iron Builder Challenge is an Online only competition with entries closing July 15th, giving you plenty of time to join in the fun and win some prizes.

What is the Iron Builder Challenge?

A creative and fun Lego building competition held at every Southern Bricks Meet Up, in which one or more Lego pieces are specially chosen by the Southern Bricks Community Builders Group to be used in your own Lego creation (My Own Custom – MOC), or other similar rules.

Bring your build to our next Meet (or post it Online for this round) and the best Lego MOC chosen by public vote wins!


Iron Builder challenge for the next round is “Christmas in July!”

Voting is open from July 15th to July 31st ONLINE ONLY with the winner chosen by the most amount of likes. We are doing it a little differently to our last Online comp, so please E-mail all entries to Luke Saurus / with the subject “SBLUG Iron Builder”
