Home Addition Contractors in Maryland

Design Build Remodeling Group of Maryland helps homeowners expand their homes without giving up what they love about where they live. We design and build custom home additions that feel like a natural extension of the original house, not an afterthought.
Many homeowners reach out to us because their home no longer fits their life. Families grow, parents move in, work-from-home needs change, and available space becomes limited. Moving often does not make sense when you still love your neighborhood, your views, and the character of your home. A thoughtfully planned home addition allows you to stay where you are while gaining the space you need.
We serve homeowners throughout Carroll, Frederick, Baltimore, Howard, Montgomery, and Northern Anne Arundel Counties.
Custom Home Additions Designed Around Your Life
A home addition should improve how your home functions and how it feels to live in it. Our team designs additions that respect your home’s architecture, flow, and proportions while adding meaningful, usable space.
We take time to understand how your family lives today and how those needs may change in the future. Every addition is planned to integrate seamlessly with the existing structure so the new space feels original, comfortable, and built to last.

Our Home Addition Planning Process
Adding onto your home involves many design and construction decisions. Our role is to guide you through that process clearly and carefully, from the first conversation through final construction.
In-Home Consultation
We meet with you in your home to understand your goals, review the space, take measurements, and discuss budget expectations.
Design and Planning
We develop conceptual designs and review layout options with you. You will have the opportunity to provide feedback and refine the plans before moving forward.
Final Preparation
Once plans are approved, we finalize drawings, review contracts, assist with finish selections, and complete site inspections and measurements.
Construction
After permits are approved, construction begins. We coordinate the build, manage timelines, and work to minimize disruption to your daily routine while maintaining quality and safety.
Home additions require patience, but when done correctly, they allow families to continue loving their homes for generations.
Home Addition FAQs
How much does a home addition cost in Maryland?
The cost of a home addition depends on size, complexity, materials, and structural requirements. After an in-home consultation, we provide a detailed estimate based on your specific project.
How long does a home addition take to complete?
Most home additions take several months from design through construction. Timelines vary depending on project scope, permitting requirements, and weather conditions.
Will the addition match my existing home?
Yes. Our goal is to design additions that blend seamlessly with your home’s existing architecture so the new space feels original rather than added on.
Do you handle permits and inspections?
