The LEGO® Group's Hogwarts Castle set captured the imaginations of Harry Potter fans worldwide, yet the community's passion for the Wizarding World called for even more magic. Enter Ryan Kroboth, a talented fan designer, who took the initiative to expand the iconic castle with his own epic extension.

Our lead designer had the privilege of collaborating with Ryan on this ambitious project. The task was to develop instructions that would make Ryan's visionary design accessible to a wider audience. Together, they embarked on a meticulous process to refine the extension, focusing on making it more user-friendly for the public market. This included evaluating part costs to ensure affordability and implementing minor design adjustments to enhance stability and integrity.
