In this step, we will make use of our road from city hall to houses. You have the choice to either update wood and stone production buildings or upgrade the road first. My recommendation is to do the first solution to maximize your production. After building the road, build the market as shown in picture.
On this image, I didn't upgrade my wood production (mistake), so now I have to wait. After upgrading houses immediately start hiring citizens in city hall so you have more people to work on upgrades.
NOTE! Every production building requires one additional worker on upgrade (one who is updating + one more to get inside and work after upgrade). Keep that in mind and hire more citizens as soon as you update any of the houses.
Although it seems simple, this phase of game is critical for creating solid foundation for future development. At this moment, try to keep your energy level between 70 and 80. If you experience shortage of any resource, go to market and trade, but as I said in previous post, don't sell iron and clay.
