Final answer:
The characteristic not associated with Augustus' building program in Rome is 'Option 4: Built a huge palace for himself'. Augustus aimed to improve the city for public benefit, not personal luxury.
Step-by-step explanation:
The characteristic that is NOT a feature of Augustus' building program in Rome is Option 4: Built a huge palace for himself. Augustus’ building program included several key elements: it established the parameters and scale of later imperial buildings, introduced a new richness of materials, and sometimes standardized certain architectural features, such as the use of columns. However, building a huge palace for himself was not characteristic of Augustus; this is more associated with later emperors like Diocletian and his Palace at Split. Augustus was careful to maintain an image of a restored Republic and even declared Rome had been turned from a city of brick into a city of marble, indicating his improvements were for the public good rather than personal aggrandizement.
