Draw vector map including buildings

I need you to draw a vector map which looks similar to this one - but not identical. It should be drawn using Adobe Illustrator. The map shown here covers about 80% of the final map. The other 20% have to be added from other maps, because this part is missing on the sample map provided here. Additionally, up to 10 tall buildings have to be added to this map, which are not yet visible on the sample map shown here. I am providing 2D computer renderings for such 10 buildings which are missing - so that you get a feeling how such buildings look like.
