SBLUG Iron Builder Challenge

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 or themes are specially chosen by the Southern Bricks Community Builders Group to be used in building your own Lego creation (MOC).

Bring your build to our  Meet – Up  on Sunday Feb 2nd at Hamra Library Hilton, place your build on the Iron Build Table and the best Lego® MOC chosen by public vote wins!

Each Iron Builder Challenge is completely open for public viewing on the day – as are our Meets! – and we encourage voters to choose the most interesting usage of the selected parts for each round.

The Iron Builder piece given to Southern Bricks members varies between events, so make sure you don’t miss our regular Meet-ups to get your bricks and battle it out to be a Master Builder!

Our latest challenge is to get creatively curvy with these cute silver arches.

If you didn’t pick them up at the last meet and can’t find them in your LEGO® stash, grab some at…

1. Use as many or few silver arches as you like.

2. Your original build must be no larger than 16×16 studs in size in all 3 dimensions – yes we’ve imposed a 16 stud height limit this time!


  • Build a  MOC out of LEGO® that is no larger than a 16 x 16 stud baseplate in size. and no larger than 16 studs high/13 bricks high.
  • “Lego®” includes Lego® System, Technic, Duplo, Belville… as long as it was produced by the The Lego® Group you can build with it! (Yes even boxes.)
  • Power functions and lighting encouraged.
  • Creativity strongly encouraged! The Builds that win usually have the most interesting concepts presented in the best way possible.
  • Prizes will be awarded based on the highest number of votes tallied by 3.00 pm on “Meet day”.
  • There will be both AFOL (Adult) and KFOL (Kids) prizes on the day. TFOL bracket can be created depending on the number of valid entries by TFOL members (3+), but prizes may not be available.
  • Please note: Prizes may vary in value between events.
