I went with them on my bathroom remodel and they did a high quality work, did everything as I requested, as they promised and all that at very reasonable costs.

"Eran and his crew at Superior Home Remodeling delivered! I truly appreciate Eran's guidance through my major home remodel. My HOA is very strict and required extensive plans and paperwork to get architectural and HOA approval. No task or requirement seemed too big or complicated for him. I appreciated his optimism during entire process. He truly loves his work and wants his clients to be happy. I also appreciated his help with design as he has an eye for what works. I am very pleased with the choice of engineered wood flooring, the quartz countertops, the tile in the bathrooms and the beautiful cabinetry. I feel fortunate to have found this company and would recommend them to anyone looking for a stylish remodel with attention to the details. A big remodel can seem overwhelming at first but Eran is patient and walks you through the steps and does the shopping with you to help you find exactly what you want. If you want personalized attention and beautiful work, you've found it with Superior Home Remodeling!"

FAQs for shelter or outbuilding building service projects in Thousand Oaks, 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.
