Metro D.C. and Northern Virginia Home Additions

room-additionsWhen it’s time to build a room addition on your home, call a Northern Virginia remodeler with style and experience. Berriz Design has been building custom room additions on homes in the Metro D.C. area since 2004.

With a custom room addition, you can increase the amount of space in your home and add custom features such as a home theater, wine cellar, home office, or sunroom. As your family grows, when loved ones come to live with you, or you want to increase the quality of your home, our D.C. area & South Florida remodeling contractors can provide you with the extra space and luxury you’ve been looking for.

Northern Virginia Home Additions we Have Done Include:


You can “bump out” a window or take down a wall to expand your current kitchen, or build on an entirely new room to create the kitchen of your dreams.

Wine Cellars

Give your collection a serious upgrade with a custom-built wine cellar. We have used brick, stone, custom ironwork, and fine detailing to create some of the most impressive wine cellars in Northern Virginia.

Home Theaters

Create a place for family fun and upscale entertaining with a custom home theater. We’ll install the audio and visual system that best suits the room’s acoustics and create a seating area that welcomes cinephiles and Disney-lovers alike.

Children’s Playrooms

Don’t let Legos, dollhouse furniture, and other playtime detritus clutter up your living space. Give the kids their own space while neatening up yours with a playroom addition. The beauty of a playroom is that you can transform it into a den, guest quarters, a home gym, or anything you wish when the kids outgrow it.


Let the outdoors in while enjoying the temperate climate and comfortable furniture of your home. We can help you create a sunroom or screened porch that’s perfect for entertaining and relaxing.

Master Suites

Sometimes a home’s original master bedroom lacks any amenities other than just additional space. Build the in-home getaway you deserve with a custom master suite from Berriz.

In-Law Quarters or Apartments

When the time comes for a family member to move in, or you’d just like to have additional living quarters to spare, let us design and build a comfortable in-law suite or apartment addition on your home.

Guest Quarters

Show your hospitality and style with a well-appointed guest suite.

Family Rooms and Dens

Make room for game nights, studying, hobbies, or alone time with a den or family room addition. With options like built-in shelving, bay windows, coffered ceilings, and more, you can have a custom space that connects seamlessly to the rest of your home.

Studios, Studies, Libraries and Home Offices

If you want specialized space for work, art, or another unique need, call Berriz. We love helping our clients realize their vision in distinctive rooms that combine style and personality with exceptional design and craftsmanship.

Workshops and Hobby Rooms

Get out of the garage or shed and into a real workshop space that accommodates your every need. With custom storage, workspace, and lighting, you’ll get more done than ever before!

Additional Garages

If you have more cars than garage space, or simply want more storage, we can design custom garage additions for your home.

At Berriz Design, we want to provide you with more than just an additional room. We design and custom-build the space to your requests while offering advice on how to make your remodeling investment even more valuable and personal.
