How long does a home addition take?

Timelines vary depending on the size and complexity of the project. Most additions take three to six months to design plus three to six months to obtain permits. Construction times range between four and twelve months including reconstructive renovation. We provide a schedule at the start of the construction phase..

Do I need permits for a home addition?

Yes. Home additions require permits and inspections. Our team handles all necessary approvals to ensure compliance with local regulations.

Will the addition match my existing home?

Absolutely. We carefully design additions to blend seamlessly with your home’s architecture, materials, and finishes—both inside and out.

Can I live in my home during construction?

In many cases, yes. We take steps to minimize disruption and maintain livable conditions, though some temporary adjustments may be necessary depending on the scope of work.

How much does a home addition cost?

Costs depend on size, complexity, and finishes. We work with you early in the process to establish a realistic budget aligned with your goals.

What types of additions add the most value?

Primary suites, kitchen expansions, and additional living spaces tend to offer the highest return on investment, especially when designed with both functionality and aesthetics in mind.
