Editorial estimate · first build
Intermediate
≈ 9 h 30 minSuggested range5 h 30 min – 15 h 15 minExperienced
≈ 6 h 45 minSuggested range3 h 45 min – 10 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
Editorial assessment: The Detective’s Office combines brick façades and urban rooms in a multi-level modular composition. Signs and little furnishings complete the ground floor. A first build following the instructions, including normal piece finding; an adult may help when needed. Breaks, subsequent play and any alternative models are excluded. For older sets, unnumbered bags or previously mixed pieces may prolong sorting. No verified timed build: indicative values with substantial variation.
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 building rhythm
Saxophone tone and space between phrases suggest an unhurried landscape. This is an atmospheric reading for natural forms and views, without assigning an undocumented geographical setting.
OUR PICK
Dis
Jan Garbarek
Intimate and spaciousA 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.
