"My parents wanted a couple of the rooms bigger in the house. So we hired Progressive Builders to get the job done. We extended the rooms about 5 feet each. The prices were great and everything turned out great. I thought it would have taken longer but they got the job done in rapid time. Thanks for all your hard work !!!"

"A GREAT experience! I chose Top Leader Construction to work with me on the renovation of my former childhood home, and as an Interior Designer I had a clear vision of what I wanted to create and achieve. I knew that I needed a top-notch, experienced and detail oriented builder who would be able to help me reach those goals, and truly my dream, for the house: creating the best of the new while respecting and honoring the past. Zack and his team were absolutely the only ones for the job! Their professionalism, courtesy, focus on quality, and ability to deal with the unexpected changes and issues that will inevitably arise on old house renovations, were exemplary. Zack and his staff were always responsive, communicative and available to work through any issues. The house is a living embodiment of the dream I had imagined, and that's very much due to the efforts and expertise of Top Leader Construction. As an interior designer, I emphasize quality materials and customer service, and Top Leader delivers that and more. I look forward to future collaborations with Zack, and would refer him as the only choice for any client seeking to renovate or build!"

FAQs for shelter or outbuilding building service projects in San Clemente, 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.
