Reporter Real Estate DeveloperMohammad Habib has made a career building Luxury Hotels and homes for the uber rich. Hello reporter such as this one showcased on bravos reality show real housewives of Beverly Hills featuring his exwife Yolanda Foster and gigi hadid. We brought these from northern california. Reporter these days hadid is not making many friends in Beverly Hills or more exclusive bel air. This is actually one of the mediumsized ones. This is about i would say 30,000 square feet. Reporter from highend developers seem to be done with mega mansions tearing them down for the new giga mansions. And nearby relevance dents like jennifer aniston, whose house is 8,500 square feet are fighting back. Voicing outrage to city officials. The very idea that a building of 90,000 square feet can be called a home seems at the least a significant distortion of Building Codes. This 50,000 square foot mansion built and lived in by hadid has a 300seat ballroom turkish bath large infinity pool and 5,000 square foot guest suite. Why build homes this big . Theres a need for it. You have customers asking for it. Reporter the ultrarich living richer. He says a new generation of global billionaires is driving this construction boom. This is not your typical inhome theater. Reporter they want it all. They expect to have a theater in these mansions. From 20 seats up to 50rr 70 seats. What is the number one amenity buyers are looking for when they are purchasing a house of this magnitude . Entertainment area. They want to have the splash to have a full 300 people at the party. You need to have bar areas, outdoor area. Something specific about a house that is different than anybody else. Reporter that includes outdoor landscaping that feels hike a resort. A Swimming Pool that stands out. Maybe two or three. And the best location. Luxury mansions soaring beyond 20,000 square feet are popping up on street after street. Some 40,000 square feet. And some reaching a staggering 90,000 square feet. Bigger than the white house and taj mahal combined. This boasts a 3,000 square foot master suite, three living rooms, salt water pool. It could be yours for 65 million. For some this giga construction seems more like giga invasion. This is the backyard. The wonderful part about this house. Reporter just yards from entertainment attorney joe horoceks front door this 30,000 square foot hall of glass and cement is being built by hadid. Do you feel hes invadeing your privacy . Privacy is completely gone. Reporter for 15 years hes lived a quiet life tucked away in the hills until hadid bought the house behind him and excavated thousands of cubic yards of soil from the hillside. I see the star ship enterprise. And i get very angry also. Whats your biggest concern . Biggest concern is a combination of the total invasion of privacy, the total disregard which i believe Mohammad Hadid has for the Building Code and for the safety of living beneath it. You think the house could end up in your property . I think theres clearly that chance. Reporter the city of los angeles is not happy either. Theyve issued a stop work order. You had your permits revoked and a stop order on construction . Correct. Why was that . Well the neighbor has complained to the city. And they decided that they want to look into it. We got our permits correctly. You can see the ocean from here. You can see its the place is a modern home. Reporter hadid showed us the property from his perfectspective where you can see horaceks house directly below. Whoevers going to live here is not going to stand here hook down.

Everyone thinks its foreign buyers . Its everybody. Local, entertainment, hedge fund banking, computer definitely Technology People then a lot of foreign buyers. 30 to 40 are foreign buyers. Reporter all this Development Comes at a price. Some irate neighbors pointing to the death of two lapd officers killed by construction vehicles. Police officer nicholas lee was killed last march when a dump truck returning from a construction site then two months later an out of control cement truck overturned on the same road. Res another truck. Theres another truck. Reporter as a result, fred rosen, former ceo of ticketmaster, who recently founded a Neighborhood Alliance cringes at every large truck in his neighborhood. Is this a regular occurrence on your street . Yeah. People at home who are going to watch and say, this is a fight of millionaires against approximately fair s billionaires. I know, theres always somebody with more, so thats not the issue. We want to be safe. The one straight ahead reporter Maureen Levin soon bel air mother of two, is a member of the Neighborhood Alliance. She became sort of a modernday vigilante over a massive 90,000 square foot property up the road. Are you with the construction site up here . Theres wildlife here. And thats the way bel air used to be. Very peaceful and quiet. Now you have a truck oh, yeah. Three trucks going through. Reporter levinsons neighbors, 8,000 and 10,000 square foot homes, are some of the homes considered to be teardowns. Thats a milliondollar view. Thats a 10 million view.

Vo the non drowsy coughing, aching, fever, sore throat, stuffy head power through your day medicine. Youre about to witness Mother Nature turning deadly in the bling of an eye. With extreme Winter Weather heading our way this Holiday Weekend were going inside an avalanche. What happens if you get stuck in a pounding rush of snow . Abcs brave matt gutman learning how to escape the hard way, firsthand. Reporter snowmobiler sam be robinson expected to charge up this mountain. Whoa challenge. Reporter he didnt expect the mountain to charge back at him. His snowmobile triggered an avalanche. His friends going to the right to avoid the tsunami of snow. Then they race to their friend. Theres also the fact that you could be going to uncover or dig out a dead guy. Reporter his buddy cleared off his face and airway. Where is he . You cant breathe and you dont know when youre going to stop. You dont know whether youre going to stop at the bottom of the 35foot pile of snow or if youre going to stop on the top. Thats the part when its most scary. Reporter but this happens all the time. This is cody strong getting blindsided. By an avalanche he never saw coming. [ bleep ]. Reporter you see him ragdoll. Check this out. See the snow on the ground starting to crack like a shattered window . A romanian snowboarder catches the moment before and terrifying moments during the time he was in an avalanche. Big mountain snowboarder Travis Wright needs all his skills to try to outrun this avalanche, deftly navigating his way down the climb. And mike lansig not the same luck. Gobbled up by the avalanche and tossed down the mountain. Miraculously hes okay. [ bleep ]. Reporter every year more than 150 people die in avalanches world wide. Avalanches can release enough snow to fill 1350 dump trucks. And can bury entire villages, like this one in italy last year. You want to get in . Reporter theyre also survivable. To learn how we traveled to avalanche country in the Canadian Rockies teaming up with avalanche experts at the resort ski patrol. Avalanches can blast down the mountain at 200 miles per hour. So if you cant move and youre in it you can think of it as a tsunami wave. Youre swimming through it. Trying to stay at the top of the wave. To not drown. Because thats the biggest concern is not being crushed to death or hit, but its asphyxiation. Cover your head to give yourself an air pocket. How much of an air pocket do you need . You dont need much. You just need enough to continue to breathe. Reporter if youre trapped, suffocation is the biggest concern. Create as big an air pocket around you as possible and try to control your breathing. Experts say you can survive for hours that way. Better yet deploy an avalanche air bag. Without that air bag, you may wind up being buried. Something i actually volunteered to do. Going six feet under in snow didnt sound that stressful at first. Get him in the hole. Reporter until i got that order. Oh, god help me. Reporter in case you cant tell i was really freaked out. Can. Reporter my sole companion, a beacon that will send out a signal to snow patrol. You can see that red light. Its a little tight. Nothing to do but wait. Reporter the patrollers dont know where i am but hale does. Time ticks by so slowly. I think i hear footsteps but its my heartbeat. Reporter 20 minutes later they triangulate my position using that beacon. Finally digging through the snow once they got close. There it is. Whoo how you doing . Youre a sight for sore eyes. Reporter in order to keep the slopes safe resorts like Kicking Horse pinpoint potential trouble areas and actually trigger their own avalanches with explosives. Basically what youre making is a rudimentary bomb. It is a bomb. Reporter they chuck those bombs over a possible avalanche so skiers dont inadvertently do it themselves. We have two bombs that we just dropped. Reporter the avalanche we expected, the blowback of black soot not so much. Making bigger avalanches means bigger explosives. Hales team detonated a pair of bombs to protect the ski trails alone. 50 pounds of explosives right there. Reporter to get a better sense of the impact of an avalanche, we recruit these two dummies. Outfitted with go pros this one even has an avalanche air bag and i pull the cord as hes lifted up. They hold out and drop right in the middle of another planned avalanche, this time using even more powerful explosives which we all get to the chopper and pile in. Ive got 50 pounds of explosives. Reporter we light the fuses in the chopper and its bombs away. Just a few minutes later, our cameras capture the moment the avalanche buries the dummies. Lodged so firmly in the snow it took weeks to get our cameras there. What surprises a lot of people about avalanche is they think, its snow, dig yourself out. Theres no digging out of it. Absolutely not. It sets up like concrete in minutes. Reporter sam robinsons friends needed shovels to get t. Would he do it again . You know the answer. Its always fun to push the extreme. For people like me. But its scary when the extreme pushes back. Reporter but maybe a little more cautiously next time. Im matt gutman for nightline.
