System Pavers is the nation’s leading outdoor remodeling company, thanks to award-winning customer service and more than 30 years of experience behind every install. With every project backed by industry-leading warranties, over 90,000 homeowners have trusted System Pavers to create beautiful, easy-to-maintain outdoor spaces where family and friends can connect for generations. System Pavers’ visionary designers and expert installation teams specialize in hardscapes, patios, driveways, turf, outdoor kitchens, BBQ islands, water features, fire features, decking, and more.

"Barely a month ago we first contacted System Pavers to consider having them replace our driveway. Today, I signed off on completion of the project, which was extremely smooth from start to finish. When James Jordan, our design consultant first met with us via video conference, he already had Google images of our property, and was therefore well prepared to discuss what we wanted to do. Based on that meeting, he prepared a first draft plan for what we wanted, which he brought to our home only about 3 days later, along with material samples. At the end of that marathon meeting, we had a game plan for a 2- or 3-phase project: first replacing our driveway and then -- if we were satisfied with phase 1, moving on to the back patio and yard. Two weeks later, construction started, with Jimmy Jackson as our Project Manager and Temo as his crew chief, and now -- less than a week later, everything is completed and beautiful. During the course of construction, we encountered a couple of minor glitches -- nothing major -- and each time, Jimmy's attitude (and that of everyone working with him) was, "no problem -- we can fix that." Meanwhile, our neighbors have been working (with a different company!) on a similar project for the past 4+ months. Needless to say, they are in awe of how quickly our transformation was completed!"

FAQs for shelter or outbuilding building service projects in Riverside, CA

A bomb shelter is an abode built to withstand disaster. Bomb shelters may refer to a space or bunker that can protect inhabitants through a hypothetical nuclear attack, apocalypse, or any other massive crisis. People usually build bomb shelters underground and stock them to live there a few days to a month at a time. Doomsday bunkers accommodate long-term living rather than just through a short crisis.

Builders construct bomb shelters with reinforced steel, box culvert, concrete, or other durable materials (but many professionals do not recommend shipping containers, as they’re not designed to live underground. If building underground, you’ll first have to excavate land before building the actual structure. You’ll have to implement air and water filtration systems, septic systems, and power supply.

It takes a lot of experience to safely and legally construct a bomb shelter, not to mention make sure it’s fit to live in for extended periods of time. It’s best to talk to a residential structural engineer near you for proper guidance.

The current standard filtration systems require filtering both air and water. For air, you’ll want an NBC filter system, which both domestic and international producers make. NBC stands for Nuclear, Biological, and Chemical, which filters out all three. If you’re only building your shelter for natural disasters, chemical attacks, and biological attacks, you may opt for the less expensive HEPA filter system. 

Water filtration requires the same level of care. You’ll likely want to have a large water storage capacity to survive short-term disasters. For long-term living, you’ll want to have a water filtration system.

Rising S bunker prices depend on the size, ranging anywhere from $20,000 to $9 million. Their least expensive model is 96 square feet while their most expensive model has a gym, swimming pool, hot tub, and bowling alley.

  • Mini: $45,500

  • Standard Bomb Shelter: $67,500–$109,500

  • Silver Leaf: $140,000–$182,500

  • Admiral: $180,000–$500,000

  • Xtreme: $450,000–$780,000

  • Xtreme Bunker Complex: $840,000–$1,830,000

  • Luxury Series: $3,800,000–$9,600,000

You almost always need a permit to build a bunker on land with any type of public utilities running through it. You’ll want to check with your local building code enforcement agency to see if this is the case for your area. 

Because you’re building a structural component that often requires electricity, water, and sewage services, you’ll need to apply for permits to attach these utilities to your new property. However, off-grid-only units in rural areas may not need all or any of the permitting you’d normally find in more urban settings.

To survive a nuclear blast, you’ll need to have your bunker at least three feet underground. However, it’s usually advisable to put it further underground. To survive a close strike, you’ll want to have the bunker at least 10 feet down and with five-foot thick reinforced concrete. However, knowing exactly how deep to build depends on the size of the blast you’re trying to avoid. Most bunkers don’t need to be more than 5 feet below the ground.
