TIME TO BUILD
How long does it take to build Empire State Building?
A starting point for planning your build. Times for each experience level are editorial estimates, not measurements submitted by HowLongToBuild users.
Editorial model estimate · no verified measured building time
Intermediate
≈ 6 h 15 minSuggested range4 h – 9 h 15 minExperienced
≈ 4 h 30 minSuggested range2 h 45 min – 6 h 45 minBased on one person building the set for the first time, following the original instructions and using numbered bags where supplied. Includes normal piece-finding and minor adjustments; excludes long breaks, filming, dismantling and modifications. Sources may use different methods. This range is neither a statistical interval nor a limit: your build may take less or more time.
How we estimate times · sources and method
Numerous repeated modules and slender cladding require careful alignment. The three central durations are model-specific editorial assessments. Planning ranges extend approximately from 65% to 145%, rounded to quarter-hours; they are not measured experience-level averages or guaranteed limits.
Sources do not always specify the builder’s experience. The three experience bands are our editorial assessment, based on the complexity of the set and individual accounts where available.

A soundtrack for your build
· Selected for the subject and atmosphere
Ravel offers finely worked sonic surfaces, reflections and shifting perspectives. A pairing for art and architecture when a model’s pleasure lies in proportion and shading rather than motion.
OUR PICK
Ravel: The Complete Solo Piano Works and Concertos
Seong-Jin Cho, Boston Symphony Orchestra & Andris Nelsons
Piano, colours and proportionsA build to spread over several sessions: choose the more understated option when you want the instructions to take centre stage. The music does not set your pace.
