As House considered the security of the Strip to be his highest priority, he also ordered an inner wall built to separate it from the area around the old Fremont Street, which soon became known as Freeside. At first, he established contact with the raider tribes in the area and recruited volunteers for building a wall around the inner city limits to better protect it, under the watch of his Securitrons and with his stockpiles of pre-war building materials. House's Securitrons finally emerged from the Lucky 38. A society that would no doubt see Las Vegas and its power source, the Dam, as theirs for the taking. These were no tribals, these were civilized people - somewhere, out in the wastes, a new society had begun. In 2274, New California Republic (NCR) scouts arrived at Hoover Dam, piquing House's interest.

In 2138, House awoke from his coma, but bided his time, watching the city be settled by tribals and raiders.

Little is known of what happened in this period of Vegas' history, although evidence of riots scar the city even today, and at least one overweight gangster similar to Don Gizmo was known to have made his mark. While many citizens were spared and even began celebrating, fallout from the warheads that did hit blew into the city, killing all of them. House was forced to make do with his relatively primitive stasis systems and although most of Vegas was saved, he suffered numerous system crashes and was eventually forced into a coma. The attack, however, came 20 hours earlier than House had predicted, and before the platinum chip could leave Sunnyvale, the city was reduced to rubble, the chip buried beneath it. The platinum chip was due for delivery by courier on October 23, 2077, the day of the Great War. To this end, he had engineers in Sunnyvale develop The Platinum Chip, a data storage device that would upgrade his defense systems and Securitrons to the Mark II OS, ensuring that Vegas and the surrounding area would be safe. House calculated that his defenses would see off the majority of missiles bound for Vegas, but at least some damage to outer Vegas and the surrounding towns was unavoidable, and that more was to be done. He also had his own hotel, the Lucky 38 Casino, fitted with radar-jamming systems, missile arrays, a laser defense network, and life-support systems. He created an army of Securitrons, some to police the Strip, but the bulk of them hidden beneath Fortification Hill for activation at a later date. He used his considerable intelligence and vast wealth to ensure that when war finally came, he would be prepared. In 2065, House predicted that a nuclear exchange between the USA and China would take place within the next 15 years, and decided to put all of his resources into protecting his home city of Las Vegas. Vegas' survival is owed to the actions of Robert House.
