After seeing some interest in Kerbin City on the forum, I looked into it, and because of the recent update to KerbalKonstructs the city is working fine in my install. Here is a step by step guide to get the old Kerbin City mod working in KSP 1.0.5. Note: I am using the 64-bit unity exe file.
Step 1: Install the most up to date Kerbal Konstructs:

Step 2: Download either of the Build 2 Kerbin City packages in the OP and install the KerbinCity folder to your GameData folder:
