The modular strength
The set is built in stackable, connectable modules, and that is the heart of its appeal. Each floor is its own detailed scene, and because the sections link to the broader NINJAGO City range, the set is a piece of something larger rather than a closed box. That expandability is a real, lasting value: it invites you to keep building the district, and it keeps the set relevant long after a standalone build would have been shelved.
The build and the detail
Assembly is a long, varied journey through the floors of the city, and the detail density is the reward, shopfronts, signage, interiors and the little narrative touches that give the place life. It never settles into repetition because each level is a different scene, and the techniques on show keep an experienced builder engaged throughout. The finished tower has strong presence and reads as a busy, lived-in slice of the city.
Value and the read
The parts are a deep and varied haul, and the modular, expandable design means the value keeps compounding as part of a larger setup. The ratio is strong for the size, with little padding. It is a significant commitment, and it is at its best as part of the wider city rather than in isolation, but for longevity and depth it is one of the standout Ninjago sets, and an easy recommendation to anyone invested in the theme.
The NINJAGO City sets are among the most beloved builds in the theme, and Workshops upholds that reputation. It is a modular, multi-storey slice of the city dense with detail and shop life, and crucially it connects to the wider City line so it can grow into a larger district. The build is long and layered, the detail rewards repeat looking, and the modular design means it stays in rotation and expands over time. It is a set with genuine longevity, the rare kind you keep coming back to, and that is what pushes its score.
