Home addition

Dannex Construction has set the standard for high quality design and build. As a full service firm, we take your project from initial concept phases through construction, so you only have to deal with one company for all your needs of home addition, home remodeling and home improvement. Whether you are looking to expand your space for a growing family, a new at-home career or a hobby, Dannex Construction saves your time, money, and hassle.

Whether you have a particular look in mind or you are starting from scratch, you can expect personalized attention from a dedicated designer that will help you promote your ideas from paper to production. Using the latest design software, we can even show you what your new space will look like before beginning any work.

From the design table, your new home addition project goes to our talented team of in-house architects and builders who will move your concept forward to construction, ensuring safety and integrity at every step. Because all of our staff is comprised of in-house, full-time employees, we have greater control over the quality and end result. Just as our designers work closely with our clients, so do our architects and builders. You can trust our entire team to work together toward completing your project – on time, on budget, and to specification.

Dannex construction is a trusted Northern Virginia (Arlington VA, Manassas VA, Fredericksburg VA, Fairfax VA and Stafford VA) home additions, home improvements and home remodeling contractors.


"WOW!! Great Experience, will request for more work by this company. Will refer to neighbors. What a great secret we have found!!!"

"Everything went incredibly well. Gina did a fantastic job meeting our very compressed timeline and was very responsive to phone calls and emails. Her guys were very thorough, friendly and did an excellent job. I would absolutely use them again on a future job."
