NINJAGO City Workshops (LEGO 71837)

About this set

This LEGO NINJAGO City Workshop (71837) packs 3244 pieces at a 4/5 difficulty, so it sits on the harder end of the line. The build is a multi-story structure split across brown, black, yellow, green and blue, with a water area at the base, a signboard, plus a crane and a mech on the outside. Sort by color first, lay the base and water section, then work up floor by floor before attaching the sign, crane and mech; the crane arm and mech joints are the tightest clutch points, and that is where most of the 4/5 difficulty lives, so test-fit with a brick separator if your fingers need a break. At 3244 pieces, plan a few evenings, and batch the repeated wall and floor parts before detailing to avoid hunting for pieces mid-build. It suits builders who have finished a few mid-size ninja sets and want a display set with scene narrative, or MOC makers into city builds; the multicolor base and sign give it shelf presence, while the crane and mech leave room for modification.
