Domus and Insula

Domus or Roman house was coordinated around colonnaded courts with open front doors enabling a look to the interior atrium. These courtyard houses were surrounded with peristyle columns which hold dining rooms, baths and kitchens. Especially the Pompeian houese were decorated. One could see paintings on the walls showing narrative scenes. The villa type emerged from the luxurious life on the countryside consisting of a larger scale with more openness for the landscape vistas. The multilevel apartment, insula, evolved after the Great Fire; they have built these blocks fireproof using brick-faced concrete on wide streets.

Hadrian took the Roman vaulted style to another level. The temple of Pantheon which was part temple part throne room provided a hemisperical space contributed to concrete technology. The dome with an oculus on the top acted with the similar task as a keystone by behavng like a compression ring to lock the structure. It was also the source of the light.
