"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!"

"We just completed our kitchen remodel in a fifty year old building. We lived in during the project and they were kind enough to keep my stove and refrigerator in use the whole time. Our Projuct Manager was Meir Bar who was great. He completd all city permits was in attendance for all inspections and was available by phone at all times even when he needed to leave the country. We had the same crew for the entire project and all were very responsive to all my questions and kept me informed as to what they were working on each day. Our project was completed within the time given at the start. The payment schedule was given to me at the start of the project and when had a change order they kept the cost at as low a cost as possible. I would use them for any future construction projects."

"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."

"Finally an honest Solar company!! I went through several companies trying to get quotes for one of my properties, either they were ridiculously expensive or they didn't return my calls. A friend of mine referred me to Mega Sun and I have to say I am very pleased. Within a couple days from the initial phone call I already had an estimate and once i decided to go with them the installation was completed in one week. Its been a little over a month since they completed the install and everything is working smoothly.

I was amazed at just how great the customer service was. I just want to say thank you to the whole team who helped out, I really appreciate all your hard work. Now I know you guys are the ones to call for all future jobs."

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