"I hired Best Austin to remove a wall as well as relocate appliance outlets. Once they started doing the work, the subcontractors did a great job. Communication was good. Occasionally I had to speak with the project manager or subcontractor to discuss with him change orders and other details. The contract took a bit longer than we expected but we enjoy the new layout of our new home."

"I can't say enough good things about J&J Constructions! We purchased a playground from Walmart and accidentally overlooked the option for assembly. We were in a bind, but thankfully J&J Constructions came through for us. They spent an impressive 7 hours building the playground, and the quality of their work was truly top-notch. From start to finish, their attention to detail was impeccable. Every bolt, board, and piece was assembled with precision and care. What stood out even more was their professionalism and character. These men are not only incredibly skilled but also humble, kind, and hardworking. They took the time to ensure everything was done perfectly, and we are beyond pleased with the result. If you're looking for a team who delivers outstanding work with a great attitude, J&J Constructions is who you need to call. They turned what could have been a stressful situation into a seamless experience. Highly recommended!"

"This project couldn’t have gone any better. The company owner contacted me and set up a time to come by. His employees arrived as promised and were very polite and efficient. They asked what I needed them to do and they went above and beyond. They completed the job in a timely manner, left the building being emptied clean and organized. The fee was very reasonable. I will call Junk Doctors first if I have any further need of hauling and cleanup. I would highly recommend Junk Doctors to anyone needing this kind of service."

"It went very well. Wally and I spoke on the phone where I explained to him what I was looking for. It was difficult to find someone who was willing to do some simple plans without all the permitting details. I explained to him how things were done in rural Vermont and he accommodated us. We spoke with Wally a number of times over the phone and worked with him interactively on his drafting program. We ultimately went to his home and spent a couple of hours talking thru the plans and making changes while discussing limitations etc. It was a very productive and helpful meeting. We ultimately came out of that meeting with a set of plans that were tweaked a little afterward and used for permitting. We have received the permit and will start in the next week or two.

FAQs for shelter or outbuilding building service projects in Round Rock, TX

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.
