|Underground Garden Plaza|
|Building Type||Unique Building|
|Milestone Required||Big Town|
The Underground Garden Plaza is a unique building that you can build if you have the Cities: Skylines Financial Districts DLC.
To unlock the Underground Garden Plaza, you need to build a Stock Exchange and upgrade it to reach level 4 (this requires ₡750,000 in investment gains). You’ll also need to reach the Big Town population milestone (1,800 – 8,000 population, depending on the map).
Once you’ve accomplished those requirements, you’ll be able to build the Underground Garden Plaza from the Financial Buildings tab of the Unique Buildings menu for ₡45,000.
Step 1: Build a Stock Exchange Building
You’ll find the Stock Exchange building in the Financial Buildings tab of the Unique Buildings menu.
It’s unlocked at the Big Town milestone.
The build cost for the Stock Exchange is ₡60,000, and the upkeep cost is ₡960 per week.
Step 2: Make Money from Investments to Level Up
Once you build the Stock Exchange building, you’ll be able to make investments.
Here’s how to do that:
Access the Investments tab by going to the “Economy” menu, or by clicking on the Stock Exchange building and then clicking the “Manage Investments” button.
On the left side of the panel, you’ll see a list of companies that have stock you can purchase.
Note: More options for stocks become available as your Stock Exchange levels up.
Clicking the “Buy” button on each stock will bring up a panel where you can decide how many stocks to buy.
You’ll also be able to see recent trends in that company’s stock price.
Any stocks you buy will show up on the right-hand side panel, and that’s also the same panel where you’ll be able to sell them from.
To make money, you’ll want to buy stocks at low prices and sell them at higher prices.
Any gains you make will be counted towards your Stock Exchange level progress.
But losing money (i.e., selling stocks at a lower price than you bought them for) will not be counted against your progress.
Of course, you’ll still want to avoid selling at a loss anyways so that your city doesn’t lose money.
Step 3: Upgrading Your Stock Exchange
You’ll first need to reach two different investment milestones before you can upgrade your Stock Exchange to level 4.
|Level||Investment Gains Target||Cost to Upgrade||Unique Building Unlocked|
|4||₡750,000||₡60,000||Underground Garden Plaza|
|5||₡1,500,000||₡120,000||International Trade Building|
Reaching ₡50,000 in investment gains allows you to upgrade to level 2. This upgrade will cost you ₡15,000.
Then reaching ₡250,000 in gains unlocks the upgrade to level 3, which costs ₡30,000.
Once you’ve made ₡750,000 in investment profits, you’ll get the option to upgrade your Stock Exchange building to level 4 for ₡60,000.
And then once your Stock Exchange is upgraded, you’ll be able to build the Underground Garden Plaza from the Financial Buildings tab for ₡45,000.
