"We did a major remodel—adding a second story, moving walls, and completely rebuilding the kitchen—and couldn’t be happier with the results. After past issues with other contractors, this team was honest, communicative, and truly cared about our project. Despite the pandemic, they finished on time and made our home the talk of the neighborhood. Highly recommend!"

"IY Development and Renovation exceeded all my expectations with our kitchen remodel. Ilan Yosef and his team not only brought my vision to life but also added their expertise to create an even more stunning result. The work was precise, clean, and on schedule.

"I cannot overstate how happy I am with Ron and his great team from Babylon Builders. I had a dream to have a greenhouse built with a hot tub inside. I was looking for an oasis and a natural garden under one roof. I searched and interviewed many contractors and I at one point thought this idea could not materialize as there were discussions from other contractors who did not seem to get the feel and flow or vision of what I was trying to capture. In addition to the build, the placement of the greenhouse had to be attached to my balcony. I came across Babylon Builders and after having a conversation with Ron I got excited thinking this could really happen. Ron came to the house within a few days and brought Juan and the crew so we could all go over exactly what we were hoping for. We hired their team instantly. They were very efficient, creative, and neat in their cleanup every day which was so important to me. Juan thinks outside the box and is a great problem solver in addition to being very talented in his ideas. Every day we would go outside several times a day to watch the magic happen. Juan and Ron fielded many questions and were always ready to answer our numerous questions. Ron and Juan are great people and take pride in their work. Their price was great too. In the end, the results were better than we imagined! I highly recommend Babylon Builders to anyone who wants great craftsmanship and a job you will be proud of."

"The Job went perfectly.
 Beau did an impeccable job attaching the conservatory to the main house without any dust or  construction debri entering the home.  He cleaned up every day after work. He kept the exact hours he said he would work. He kept the job on schedule.
He worked with the city on all the permitting and inspections.
The quality of workmanship was well beyond my expectations and became the envy of everyone who saw the finished room.
Beau came in right on bid. NO COST OVER RUNS!

I would highly recommend him for any job from building an entire home to remodeling that garage you have been putting off for a while."

"I’ve been working with Cobar Builders for a while now and was great with multiple jobs in my home. From our full kitchen remodel to upgraded can lights all around, added new beautiful 3” LED lights in my dark living room. He changed my sliding door to a lovely French door. I’m very pleased with their work and always turn to them"

FAQs for shelter or outbuilding building service projects in Sebastopol, 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.
