We started the summer with a crab fest!

The porch looks great! We christened it this weekend with a crab feast!   Our daughters barely recognized it from the old porch!
The weather will be cooling and  we will get so much use out of it. Your guys were GREAT to work with! No matter what the question or issue,  you addressed it.   Thank you!

Loved your team

Design Builders is a 5-star company. We have a screened-in porch and we got tired of constantly cleaning the pollen each spring as well as having rain and snow get into the porch. I did extensive research and decided to go with Sunscape vinyl windows over ez-breeze windows. I found several good reviews for Design Builders.  I was not disappointed.

3rd time a charm

"We needed to redo our deck.  Having had multiple issues with 2 previous companies, work that needed to be gutted, the 3rd time was truly a charm. Everything Design Builders promised was accomplished and delivered.   Their team was extremely responsive (regular reports and photos),  knowledgable with all aspects of the project and materials, and very professional.

Covering Todays Trends

For homeowners across Northern Virginia—from Vienna and Arlington to Fairfax and Ashburn—the demand for beautifully designed, low-maintenance outdoor spaces is booming. And it’s no surprise: with changing lifestyles, hybrid work setups, and a renewed emphasis on family time, custom decks are no longer a luxury—they’re a lifestyle upgrade.

If you live in Ellicott City, Clarksville, Fulton, or Columbia, chances are your backyard is full of potential. In Howard County, where spacious lots and upscale homes are the norm, more families are asking: Is it time to build an outdoor kitchen?
