Frequently Asked Questions About Home Additions

The cost of a home addition depends on several factors, including the size of the addition, structural work required, foundation type, roof design, interior finishes, and the complexity of the project. During your consultation, we’ll discuss your goals, evaluate your property, and provide a detailed proposal based on your specific design and scope of work.
Most home addition projects take between 6 and 10 months from the initial consultation to project completion. This timeline typically includes design, engineering, permit approvals, material selection, construction, inspections, and the final walkthrough. Larger or more complex additions may require additional time.
In many cases, yes. Most homeowners remain in their homes during construction, especially when the work is limited to a new addition. There may be temporary disruptions such as noise, dust, or utility interruptions during certain phases, but we work to minimize inconvenience whenever possible.
Yes. Nearly all home additions require building permits, structural drawings, and inspections to comply with local building codes. Permit requirements vary by city and county. Our team helps coordinate the permitting process and works with local jurisdictions throughout Washington, DC, Northern Virginia, and Maryland.
Yes. One of our goals is to make your addition look like it was part of the original home. We carefully match rooflines, siding, brick, windows, trim, exterior finishes, and architectural details whenever possible to create a seamless appearance.
We build a wide range of home additions, including first-floor additions, second-story additions, primary suite additions, kitchen expansions, family room additions, sunrooms, home offices, bedroom additions, bathroom additions, in-law suites, garage additions, and custom room additions.
Several factors determine whether a home addition is possible, including lot size, zoning regulations, setbacks, easements, utility locations, and the existing structure. During the planning phase, we evaluate your property and discuss the options available for your home.
Every project is different. Some additions require a new foundation, while others may involve reinforcing existing structural elements. Our structural engineer evaluates your home and designs the appropriate foundation and framing system based on the approved plans and local building codes.
Yes. Many home additions include removing load-bearing walls to create larger, open-concept living spaces. When structural walls are removed, engineered beams and posts are installed to safely support the home’s structure.
You’ll be involved in the key decisions, including approving the design, selecting materials, reviewing finishes, and discussing any requested changes. Throughout construction, we’ll keep you informed about the project’s progress and upcoming milestones.
Changes are common during remodeling projects. If you decide to modify the scope of work after construction begins, we’ll review the requested change, discuss any impact on the schedule or budget, and provide a written change order for approval before the work proceeds.
A professionally designed and properly constructed home addition can increase your home’s functionality and may improve its market value. The amount of added value depends on factors such as the type of addition, quality of construction, location, and current real estate market conditions.
We take steps to protect your home throughout construction by using floor protection, dust barriers, temporary weather protection, and daily job site cleanup. Our goal is to minimize disruption while maintaining a safe and organized work environment.
Most home additions require inspections at various stages of construction. These may include foundation, framing, plumbing, electrical, HVAC, insulation, and final building inspections. The exact inspection sequence depends on local building requirements and the scope of the project.
Before construction starts, we recommend removing personal belongings from the work area, protecting valuable items, discussing parking and site access, and making arrangements for pets or children if necessary. Our team will review the construction schedule and answer any questions before work begins.
A design-build approach provides a single team responsible for planning, design, engineering, permitting, and construction. This helps improve communication, reduces coordination challenges, and creates a more streamlined experience from concept to completion.
We stand behind the quality of our workmanship and provide a one-year workmanship warranty on completed projects. Manufacturer warranties for products and materials are provided separately by the respective manufacturers and vary depending on the product installed.
