"Ryan and his crew did a great job building out Car Port. From the first time we talked to a completed project was about 6 or 7 weeks. He and his crew were very professional and, came on time, and exceeded my expectations with respect to the quality, time to finish, etc. Ryan also collaborated with another team of professionals that were contracted to place Solar Pannels onto the Car Port that was just completed. He made sure that all of their requirements and spec were addressed while building the Car Port. THANK YOU Ryan and Co!"

"I could not be any happier. Scott was a pleasure to work with from the start...his plans were very professional, and he was very experienced in working with the county on getting the proper permits and approvals. Scott was there every day, rain or shine, and we did have some inclement weather for part of the project. We made a few changes on the project as we went on and Scott was always very responsive to my questions and concern. He was always very polite and had a very positive attitude throughout the deck project. Anybody who needs a beautiful deck done by a true professional cannot go wrong with Scott. I am so happy with his work I have a couple more projects that I will have Scott perform for me....he is a true craftsman, and his attention to detail and the quality of his work made this a very rewarding and happy experince...I would recommend Scott to anybody!"

"It was a pleasure doing business with these fine craftsmen from start to finish! The quality of their work was far beyond what I expected. I was so impressed with their work ethic and professionalism. They truly listened and were collaborative through the entire build. Each day they were on-site, they worked very hard and with a cheerful attitude as well! My new custom shed is exactly what I wanted and I would hire them again in a heartbeat."

FAQs for shelter or outbuilding building service projects in Seattle, WA

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.
