City Upgrades

Contents

Overview

City upgrades are special buildings found in the Extensions tab of any house info window. The bonus received will apply to all the houses standing in the catchment area of each such extension regardless of which house's Extensions tab the building was chosen from. Warning: There is distance limit on building ANY of the city extensions. You may build it no more than 4 squares from the the closest city building. In other words, you can have 4 empty squares and the building must be placed on 5th square from the closest building. Buildings bigger than 1x1 have ONE square of their footprint assigned as the "Main" one. That square is the one which must be at the 5th square from the town, you might have to rotate the building to be able to place it on desired location. Different extensions get unlocked as you progress through the eras of the game. There are three main types of town upgrades: Public Services, Relax and Luxury, and two special: Constructions and Pollution Zone

Pollution Zone

Each and every industrial building (with the exception of Forest) have a pollution zone around itself. The size is different for each building and you can see it in the info window.

You can see it in the city overlay as rusty brown zone around industrial buildings. Also train platforms have 1 square pollution zone around themselves. The station buildings and decorations do not have pollution zone, neither do the road stations. It is advisable to block the pollution zone at the train station by placing station upgrades and/or decorations around the platforms.

The Pollution zone prevents houses from being upgraded. The effect of the pollution zone is permanent and cannot be canceled by building other city upgrades nearby. You can either have small level 1 houses around industrial buildings as "workers quarters" or you have to place the Construction prohibited extension, or other some other extensions, just to block the area.
