Construction and demolition
Construction
Floors
Your tower is constructed of floor tiles. Floor tiles must be placed in a location where it is supported: Anywhere on the ground floor, above an existing floor tile if building above ground, or below another tile if under ground. When building rooms and placing wallpaper tiles, floor tiles will automatically be placed.
Floors have a minimum separation distance. Building too close to another floor tile will automatically merge floor spans. You can demolish built floors. However, the minimum spacing distance still applies.
Floor tiles can be built by clicking and dragging. If you want to build multiple floors at once, use the shift key while dragging.
Tip: You can use the f key to select the floor tool.
Rooms
Rooms must be placed at at a location where its floor tiles are fully supported. Multiple rooms can be built on the same floor by clicking and dragging. You can build multiple rooms across multiple floors using the shift key while dragging.
Certain rooms can be relocated such as the vending machine. Using the cursor tool, you can click and hold the room to relocate the room.
Wallpaper tiles
You can decorate your floors with wallpaper tiles. These are decorative and also boost the environmental score in the area. Lobbies are treated as areas decorated with the lobby wallpaper tile.
Most wallpaper tiles can be customized with custom colors. Use the query tool to change the color of an entire wallpaper section.
Tip: You can use the picker tool to copy existing wallpaper styles and their colors.
Skybridges
You can join two towers together with a skybridge. Select the skybridge item and hover/click somewhere between two separate floor tiles to build a skybridge.
Demolition
Select the demolish tool from the tool palette or use the X or Delete key. Click or drag over an area that you want to demolish. The rooms, transports, or tiles to be removed will be highlighted in red and the cost/refund amount will be displayed.
Floors
Floors can only be removed if it is not load-bearing where another floor tile or transport system depends on it.
Elevator cars
You can remove existing elevator cars by demolishing a car. You may not remove the last car as all elevators require at least one car to function.
Refunds and costs
If refunds are enabled, most build items will refund half the construction cost after being built for one full day. A full refund will be given within the first day of construction.
