"Our kitchen was in dire need of upgrades, and we met with many different contractors for estimates. Young from New Life Construction left the best impression by far, from his professionalism, renovation ideas and design, reasonable pricing, etc. I am so glad we decided to go with New Life as Young and his entire team were a delight to work with from start to finish. We received very helpful opinions regarding many aspects of the design and materials without it being overbearing, and it was helpful to see his previous projects through instagram (@newlife_construction) to see what has worked well for similar kitchens in the past. There was clear communication about everything from details of the job to scheduling and everyone was very attentive to our needs throughout. This company handled the demolition, cleanup, cabinets, countertops, overhead lighting, painting, appliance installation (range/oven and dishwasher), sink and faucet installation for us-- pretty much everything in the kitchen except the floors. They bring in separate contractors that are specialists in their respective field (cabinets, countertop, etc) to do each portion of the project so you know you're truly getting the experts at every step of the way. Even after the project was done, Young went above and beyond to wrap up last-minute issues that came up from cabinet parts that were on backorder and to this day is responsive to any issues that may come up in the future. My family and I are so happy with how the kitchen turned out and we would not hesitate to hire Young and his team again for future projects."

"My husband and I are in our 70’s. All of the upgrades/construction in our house in over 26 years was done by my career-construction husband. But recently he hurt his back. We needed our guest bath prefab bathtub/shower removed and replaced with a NICE prefab WALK-IN shower handicapped out. Our 95-year old mom was coming for a 2-week visit. We only had 3 weeks notice. Ani Kevorkian, owner of LGC Construction came to our house 1 day after I called. She listened, REALLY listened to what we wanted and understood the time constraint. She gave us a quote within hours and started the job within days. Her two gentlemen who came out were just awesome and cleaned everything up each day. Then Ani surprised us with “barn-door” glass shower doors that we didn’t even know we were getting. The shower is just beautiful! This company is exceptional. I have and will continue to tell our neighbors, people at our church, friends, etc. about LGC Construction! You can TRUST THEM!!!!"

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