"We had a phenomenal experience with National Home Design & Build and can’t recommend them enough. Patrick was with us from concept to permitting to demo to build and we are absolutely thrilled with our new space. We had a loft space that made several hundred square feet of unusable space in our house. Patrick worked with us to understand the design options, work us through the concept and process, did all of the permitting and managed the process from start to finish. We now have a full third bedroom in our house, a brand new walk-in closet, a new ceiling and lighting in our kitchen and we also had them replace all of the carpeting in our second bedroom, hall, two staircases and a closet. We can’t recommend them enough and Patrick will be our first call the next time we need to renovate."

"I had an incredible experience with Thomas Custom Builders! They not only added a beautiful addition to my house but also completely transformed my master bathroom into a luxurious retreat. From start to finish, their team was professional, efficient, and attentive to my needs. The craftsmanship and attention to detail exceeded my expectations, and I couldn't be happier with the results. I highly recommend Thomas Custom Builders for any home remodeling project!"

"We interviewed several contractors before we decided to work with Cosmo Builders because they were quick to respond to our inquiries and nicely explained the building and permitting process in the first free consultation. At the end of the bid evaluation, I found the Cosmo estimate more reasonable and the full detailed cost estimate clearly stated, from plumbing, electricity, drywall, HVAC, etc., to finish. Also, during construction, the owner, Mr. Alkozay, was extremely helpful in the selection of finishing materials and fixtures based on our budget. They just transformed our unfinished basement into a finished one by adding a kitchen, full bathroom, laundry, office space, a family room, and a gym. The Cosmo management team was excellent and truly helped us manage our vision and budget. On our building journey, they did excellent work. I highly recommend the Falls Church neighborhood."

"A few years ago, Gary and his crew did a wonderful job on our bathroom which is why we have hired them to do our kitchen upgrade. Fair pricing - very hands on. Over 30 yrs of experience so they've seen it all and can guide you through the jungle of options for pretty much any project. The crew are all very friendly and do an exceptional job. We will gladly hire them for the next project."

"We hired Capstone to remodel/upgrade the master bathroom in our townhouse. It is a small bathroom and the total remodel took about two weeks and was completed on time and on budget. We couldn't be happier with the results, and our experience with Capstone from start to finish was excellent. I specifically want to highlight the excellent craftsmanship and attention to detail in all aspects of the work, including plumbing, electrical, drywall, painting and especially tiling (did an amazing job with the glass tile accent wall). Everything looks absolutely perfect and is functional. Furthermore, Stephen and his crew were always very pleasant, kept the work area as clean as possible, and were great at communicating (ideas/recommendations, challenges that came up, and any additional costs) through the duration of the project. We highly recommend Capstone for any bathroom remodel project and will definitely use them again in the future."

"US Home Design Build proved to be an outstanding choice for my wife and I to custom build a high quality, two story addition (four season sunroom and covered patio) onto our 1968 colonial style home in Fairfax County, Virginia. Our vision for such an addition was to involve the meticulous planning, design and construction of a highly custom, expanded living space, utilizing the finest materials, fixtures and hardware. The design was conceived to appear wholly integrated into the existing architecture of the residence; as if built at the time of the home's construction. After interviewing a variety of custom builders, we chose US Home Design Build. Simply stated, we were thoroughly impressed with the professionalism and reputation of US Home Design Build, along with their representatives Mr. Sean Brennan and Mr. Min Yi. From the outset, the project proved challenging, yet Min Yi and his crew never failed to provide us with impeccable quality of craftsmanship and a conscientious work ethic. Min would frequently suggest practical improvements to the design, construction and associated hardware of the ongoing project; all at no increase in cost. Min always listened carefully and never failed to satisfy my every concern and stated objective. Even unavoidable delays (associated with third party design and construction of elaborate custom windows and doors) never disrupted the focus, momentum or morale of US Home Design Build. The project was completed flawlessly; on schedule and on budget. My wife and I could not be happier. We now have the four season sunroom and patio of our dreams, thanks to Min and his crew."

FAQs for addition to existing structure building service projects in Alexandria, VA

You can typically raise your roof by four to eight feet, depending on your home's structure and roof design. The exact amount depends on factors like roof slope and framing support. Raising the roof creates additional interior space, enhances natural light, and increases your home's value. Consult a professional to determine the feasible height increase for your home.

Yes, you need a building permit to raise your roof. Obtaining a building permit ensures your project complies with local building codes and safety regulations. A professional contractor can assist with the permit and inspection process and ensure all legal and safety requirements are met. Your contractor will be familiar with building codes in your area, which can differ between cities or states.

While it's possible to raise a flat roof, it requires extensive structural modifications. Flat roofs lack the attic space and support structures of pitched roofs, so raising them involves significant engineering to ensure safety and durability. This process can be complex and costly, so professional assessment is essential before undertaking a project of this magnitude.
