|Milestone Required||Big Town|
The Official Park is a level 3 unique building in Cities: Skylines.
To unlock it, you must have 10,000 squares of office zone. You’ll also need to reach the Big Town milestone (1,800 to 7,500 total population, depending on the map).
When these requirements are fulfilled, you’ll be able to build the Official Park from the level 3 tab of the Unique Buildings menu.
Although the level 3 Unique Buildings menu is available from the Boom Town milestone, you’ll need to reach Big Town to start zoning offices (as well as build a university, which is crucial to office zones).
The Official Park is one of the requirements for the Eden Project monument.
Creating Office Zones
Offices are created by painting the office (cyan) zoning tool from the Districts and Areas menu. This tool is unlocked at the Big Town milestone.
Getting Demand for Office
In order to count towards the unlock progress, the 10,000 squares of office zone will need to be built upon (not empty zoning).
This means you’ll need to have actual demand for offices in your city.
Similar to industrial demand, the demand for office zoning goes hand in hand with growing your population. In other words, you get demand for workplaces when there are people in your city that need jobs.
This means you should expect to grow your city in general as you work towards this unlock.
Educating Your Citizens
In contrast to generic industry, which employs a lot of uneducated workers, office zones need educated employees, including a lot of highly-educated ones.
This means you’ll have to make sure your city has enough educational facilities—for all three levels—to generate the workers for your office zones.
Building a university (or any of its DLC equivalent buildings) will be key to growing your office zones.
Tip: Office zones that lack educated workers for too long will eventually get abandoned.
