Sets designed by Ivan Guerrero

Featured BrickList Compiled by bulldoozer. Updated 12 August 2025. Contains 3 sets.

Since joining The LEGO Group in March 2025, I’ve designed these sets as a model designer or made significant contributions as a concept designer. I’ve also included my three LEGO Ideas sets, originally created when I was a fan designer.

Each one is the result of collaboration, brought to life through the creativity and dedication of talented colleagues and partners.
