You will find us to be competitively priced with close attention to the details of each and every project with which we are involved. We look forward to building lasting relationships and guarantee your satisfaction!

"If I could give this company a 6 out of 5 stars I would! They did a fantastic job overhauling my mother's deck, back patio, fencing, and front portico. All of the work was absolutely essential for safety and structural reasons, and I'm so glad I chose OSSA to do the work. My mother has Alzheimer's, which presented additional issues, but the entire crew was incredibly kind, respectful, and understanding of the unique challenges they faced. They were responsive and kept me aware of everything regarding the job along the way. My mother is so pleased, and I have the peace of mind that all of her outdoor space is safe, beautiful, and accessible. I will be hiring OSSA to do some work in my own home, as I look to make necessary improvements in the future. I've told everyone I know how how wonderful they are. 6 out of 5 stars!"

From our initial meeting to the completion of your project, our number one goal is to exceed your expectations. We install economical projects with great resell value along with large outdoor living staycations. When you choose to work with us, you get a project manager to communicate important information and oversee the installation of your project. Before we can begin construction, there are many tasks that must be completed. We do this efficiently by using project, customer service and communication tools and technologies along with a great staff that all share the same vision of excellence. Below are the steps we take to ensure you are 100% satisfied with your choice.

"HD Exteriors replaced our 20 year-old wood deck with a beautiful new Trex deck in April. We had gotten 4 presentations from companies based on contacts we got from the Capital Home Show, and HD Exteriors was head and shoulders above all the others in design, detail, cost, and communication. Graham Jr., was our point of contact in setting our contract, and he was friendly, knowledgeable, professional, and clear. He listened to what we wanted to do, offered suggestions and didn’t try to upsell us. We were given a start timeframe, but our actual start date was earlier, which we appreciated. Throughout the entire process of signing the contract, having questions answered, being assigned a project manager, (Jai, who was always accessible and awesome) and the actual work being done, the communication was excellent. We were notified when workers would be onsite, when inspections were scheduled, when walk-thrus were done, and had access via text to our PM. All of it was extremely well done. The deck was finished with excellent workmanship, even when they installed a style of steps they’d never done before. We can’t say enough positive things about the entire company and how they operated. They were a pleasure to work with. We’re just sorry we don’t have anything else for them to build!"

Visit our website to request your free in-home estimate today! Phoenix Home Services is a locally owned and operated turn-key construction company servicing the Northern Virginia area. We have been in business since 1985, with many beautiful projects under our belts. Our committed and tight-knit team is fully capable of projects as simple as a small patio installation, to larger jobs such as full house or business construction, and everything in between! As a general contractor with years of experience installing complex projects and strong ties with the area's suppliers, Phoenix Home Services is a sound choice and good value for all your home improvement needs. From building a custom screen room, to renovating a basement… Let Phoenix breathe new life into your home!

"We are three projects in with Phoenix and will do more when the budget allows. Cannot say enough great things about their vision and design for our extra large deck and enclosed patio directly below it. We took ‘go big or go home to heart.’ Had not planned on the enclosed patio below but when Clint sent us the mock-up designs we were all in. When I say all in, we did the Trex Signature cable rails with accent lights, straight walkout from upstairs (required a creative roof change), Trex Rain Escape, and custom Eze Breeze windows for the patio. Post completion we went back and asked for a flooring add, exterior walkway add and two more projects are pending our budget. Phoenix delivered as promised, showed up when promised, and stood behind their word. We always knew where we were with the timeline and someone either answered the phone or called us back whenever we reached out. The entire team works great together and their communication skills met every expectation we had. We really could not have asked for better. Highly recommend."

"We are extremely pleased with our lovely patio which was built by Nelson almost a decade ago. From the start it was executed properly from a beautiful design, grading away from house, putting a sturdy, non-destructible base with layers of gravel and stone and then the beautiful papers. Nelson, a truly skilled mason and professional, was reliable, efficient and methodical in completing the project for us on time and within budget. The recent patio refurbishment refreshed the patio and made it look brand new again. I highly recommend AVEC."

FAQs for shelter or outbuilding building service projects in Annandale, VA

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.
