Alternate builds for LEGO sets have long been part of the fun. When I was a kid, I remember loving to see the variants featured on the back of the box. As a young fan of LEGO, it inspired me to look at that box of bricks in a different light — to try my hand at my own alternates. Twenty years later, I can count myself amongst a crowd of LEGO fans devoted to alternate builds. Though you can find all sizes of re-imagined sets, few are as ambitions as builder Lucas Bolt and his Modular variant of the microscale 71043 Hogwarts Castle. Inspired by the magic school aspect, Lucas created the University of Cambricks to fit perfectly on the corner of a LEGO Modular city street.
