Here's my full City layout that I plan to build. There are only 2 buildings that are sets: The modular "Town Hall" and "Pet Shop". All of the rest will be created by me! The table on the bottom may or may not fit in the layout. If not, I will continue building in another room. In addition, I hope to someday build a space city.
Each MOC will be an individual build, and I'll be integrating them along with the roads and infrastructure as I go along. The "Zoo" on the top-right will be comprised of multiple animal exhibit MOCs (starting with my bird exhibit which is complete).
The monorail will run from the airport to the zoo, and may tunnel through some buildings as needed. The Maersk train will not be motorized, and will be stationary, while the Horizone Express train will run in a loop.
Planned MOCs, in order that I wish to complete them:
