Here's a city plan I sketched out for once we've found a suitable location. With the amount of people we now have I envision a more communal layout, so I've gotten rid of the individual homesteads of old and divided the village into three fairly standard zones: agricultural, residential, and industrial. The plan will probably be increased in scale depending on the population.
green - farms. can be extended to the north and wrap around the sides of housing.
dark gray - stone mansion. storage area. temporary housing for new residents. also a place for cheese production with a cellar.
brown - log cabins.
the center - oak tree (green), village idol (white), poppies/decorative plants (violet)
peach - leather production, kilns, ovens, etc. trees should be planted here for fuel access.
blue - the water source. alternatively, we might consider moving inland since raiders are more likely to target riverside villages. in this case a well would replace the river.
