Berriz Design Build has been designing and building custom room additions for homes in the Northern Virginia area since 2004. As your family grows, when loved ones come to live with you, or you want to increase the quality of your home, our remodeling contractors can provide you with the extra space and luxury you've been looking for. ## Why Consider a Room Addition? As your needs change, your home should change with you. Room additions offer a flexible solution that allows you to stay in the neighborhood and home you love—while gaining the extra space your lifestyle demands. Common reasons homeowners pursue additions include: - A growing family requiring more bedrooms or bathrooms - Aging parents needing a private in-law suite - The shift to remote work creating demand for a dedicated home office - The desire for a larger kitchen, mudroom, or entertainment area - Maximizing property value before selling Whether you want to build up, bump out, or create a seamless extension of your existing home, our expert team will tailor the design to meet your needs, your home’s architecture, and your budget. ## Types of Room Additions We Specialize In No two homes—or homeowners—are alike. That’s why Berriz Design Build offers custom solutions for a wide range of room addition projects, including: ### Second Story Additions Maximize your footprint without sacrificing yard space by building up. We design and construct full second-story additions that blend beautifully with your existing structure and provide spacious new living quarters. ### Bedroom & Bathroom Additions Perfect for growing families or creating a guest suite, adding a bedroom and bathroom can make your home more accommodating and valuable. ### Sunrooms and Family Rooms Expand your living area with a bright and airy sunroom or a cozy family room perfect for relaxing or entertaining guests. ### In-Law Suites Whether you're caring for aging parents or planning for multi-generational living, we design complete in-law suites with private entrances, kitchenettes, and bathrooms for comfort and independence. ### Garage Conversions Transform unused garage space into a guest room, gym, office, or art studio with a design that feels completely integrated with the rest of your home. ### Kitchen Expansions If your kitchen feels cramped or outdated, we can reconfigure your floor plan or extend your space to accommodate modern appliances, open layouts, and ample storage. ## Seamless Design & Build Process At Berriz Design Build, we simplify the remodeling experience by offering full-service design-build solutions under one roof.

Our expert designers and craftsmen focus on seamless transitions—matching rooflines, materials, interior finishes, and layout so your new space feels cohesive and natural. Whether you live in a Colonial, Cape Cod, or modern Craftsman-style home, we tailor our design to enhance your existing architecture. ## Budgeting for Your Room Addition Room additions are a significant investment, but they offer lasting value—both in terms of everyday comfort and future resale. Costs can vary depending on the size, complexity, and finishes of the addition, but our team works closely with you to create a design that fits your goals and your budget. We provide transparent estimates, outline all options, and never compromise on quality. ## Frequently Asked Questions (FAQs) How do I know if a room addition is right for my home? A room addition is ideal if you love your current home or neighborhood but need more space. Whether it’s a growing family, aging parents moving in, or the need for a home office or larger kitchen, room additions allow you to tailor your home to your current lifestyle. Our design team will evaluate your property, local zoning codes, and structural considerations to help you determine what type of addition makes the most sense.

Will my addition look like it was part of the original home? Yes—seamless integration is one of our specialties. At Berriz Design Build, we prioritize architectural harmony. We carefully match rooflines, materials, windows, siding, flooring, and finishes so that your new space feels like it has always been part of your home. Our design-build process ensures consistent quality and attention to detail from start to finish. How long does a typical room addition project take? The timeline varies depending on the size and complexity of the project. A small bump-out or room extension might take a few months, while a full second-story addition could take longer. Our team will provide you with a detailed project timeline during the planning phase and keep you informed at every stage to ensure a smooth, stress-free experience. Do I need permits for a room addition? Yes, most room additions require building permits and must comply with local zoning laws, building codes, and HOA guidelines if applicable.
