As your family grows and needs change, you’ll eventually be faced with a tough decision — should you move to a larger house or add additional space to your current home where you’ve already made countless memories? Many homeowners opt for the latter. And that’s where Sun Design comes in.

At Sun Design, we understand the importance of this investment and want you to be completely satisfied with your home addition. Whether you need to create additional bedrooms for a growing family or would like extra space to get work done during the day, our team can help. We have the experience to transform your space creating the following types of home additions in the Northern Virginia and Montgomery County, MD area:

  • Kitchens & Dining Space: Thinking beyond the rectangular closed off rooms by designing and constructing a space that flows seamlessly from one room to the next with enough room for you, your family and guests.
  • Family Rooms: We help families redefine their living spaces, making it easier to spend time together and providing a more functional and enjoyable space for all.
  • Master Suites: Your master suite is your own personal zone. We make sure it has the storage, light, counter space, walk-in closets, spa-like feeling, make-up counters, bath and shower you need to feel comfortable.
  • In-law Suites: Rather than one cramped shared space, add onto your home, creating separate spaces. This space is designed to meet your family’s individual needs with a focus on aging in place.
  • Dens and Home Offices: We create one-of-a-kind personal spaces that you can use as a traditional den or office or a space to enjoy your favorite hobby, such as a wine cellars, yoga rooms, or an entertainment room.
  • Garages: A garage home addition should fit seamlessly with the design of your home and provide the storage and security you need for peace of mind.
  • Sunrooms & Porches: If you’re looking for a way to combine indoor and outdoor living, look no further. Our designers will help you create spaces in your home that allow you to enjoy all four seasons and use the natural light to its fullest potential in your home.

There’s nothing more important than meeting, and exceeding, your expectations. Our focus is on creating unique, personal solutions and ensuring you’re in love with the end result.

What Our Clients Say

“John and I wanted you and your staff to know how much we appreciate the fine job you did designing and building the addition to our house. It is exactly what we wanted – and at the same time you managed to save the upstairs window using the roof design we had chosen. Before we met you, two different architects we hired to draw our plans said what we wanted couldn’t be done, but Sun Design did it!! You are a fine young company built on honesty and integrity. We wish you continued success in the future, and we’ll be looking forward to working with you again.” – M.L.

“As a downshifting senior I am very pleased w/my addition to my daughter’s home. I am only a doorway away from family and yet have the privacy and independence I desire now w/a nod to future attentions I may require. Sun followed recommended ‘universal design’ developed for the disabled w/wide doorways and bathroom access for wheelchairs if ever there should be a need. From designers to contractors there was a warm but professional ease of relationship. The project manager made sure the T-s were crossed and i-s dotted w/daily schedule updates. Sun took the anxiety out of this daunting action and made it fun. Thanks, guys!” – C.M.
