Residential Area Output and build times
The residential area is where gold resources are generated. You require gold to create and upgrade buildings as well as to make purchase from the Trading Center. You can have a max of 12 residential areas fully upgradable to level 24 according to the game data files. A minimum level of Civic Center is required to upgrade the Residential Area.
Once you have a full set of level 12 residential areas it begins to become cost effective to build Landscaping Structures. A level 16 residential area will cost 1.33 million resources and will give 780 per hour. A 1% landscaping structure will cost 0.88 million resources and gives 550 per hour. If you have significant resource collection bonuses through Corp membership then it is far better to upgrade your residential areas as the 780 is multiplied by your corp bonus while the 550 is not. This is also true to a lesser extent with bonus gold from research but it won't be significant enough unless you are close to maxing out the 10% bonus.
