Frequently Asked Questions From Homeowners Like You

How Much Does a Home Addition Cost in Chicagoland?

Most additions range from $375 to $525 per square foot and beyond, depending on size, complexity, and the level of finishes.

During your consultation, we’ll review your goals and help you understand realistic budgets for your specific project. We’ll also walk you through how different design choices (such as layout changes, structural needs, and premium features) can impact cost. Because we use a design-build approach, you’ll have clear pricing before construction starts, with no surprises along the way.

How Long Does a Home Addition Take?

Project timelines vary, but most additions take 8–20+ weeks after design approval. We'll give you a clear schedule up front so you know exactly what to expect.

Larger or more complex additions may require extended timelines due to structural work, material lead times, or seasonal weather conditions. Throughout the project, our team provides regular updates so you’re always in the loop and never left guessing.

Can I Live in My Home During Construction?

In most cases, yes. We take steps to minimize disruption with dust protection, clear pathways, and a clean jobsite throughout the entire project. Depending on the scope of your addition, certain areas of your home may be temporarily inaccessible, but we’ll help you plan around those phases.

Our communication-first approach ensures you always know what’s happening and how it may affect your daily routine.

How Do I Know If My Home Can Support a Second-Story Addition?

During your consultation, we evaluate your existing structure and foundation to determine whether your home can support a second level or if reinforcement is needed.

We’ll also review local building codes and zoning requirements to confirm what’s possible on your lot. If a second story isn’t structurally or financially ideal, we’ll recommend alternative ways to add space without compromising safety or design.
