Home Addition FAQs

How much does a home addition cost?expand_more
The cost of a home addition depends on factors like size, design complexity, and materials. A single-room expansion costs less than a multi-story addition or a kitchen expansion with custom cabinetry and high-end finishes. We provide detailed estimates upfront, ensuring you understand the scope and budget before construction begins.
How long does a home addition take?expand_more
The timeline for a home addition varies depending on the project’s scale. Smaller additions may take a few months, while larger or more complex expansions can take six months or longer. Our team carefully plans every stage to ensure efficient progress while maintaining quality craftsmanship.
Will an addition blend with my home?expand_more

Yes. Our design process ensures that every addition integrates seamlessly with your existing structure. From matching exterior materials and architectural details to maintaining a natural flow inside, we ensure your new space looks and feels like part of the original home.

What should I consider before adding to my home?expand_more
Before starting a home addition, consider your long-term needs, budget, and how the new space will connect with your existing home. Structural integrity, zoning laws, and architectural cohesion all play a role. Our team helps you navigate these factors to ensure a smooth and successful project.

Spacious bedroom with wooden flooring and a cozy bed, a project by Oxland Builders in New Hampshire

What Our Clients Think

"We recently had to move our in-laws in with us and needed to build them a room. We met with Brad and he was able to quickly assemble a team to create a space that was suitable for them. I can’t thank Brad, Claudia and the whole Oxland Builders team for finishing this project in record time. They are thorough, punctual and super organized, and thanks to the Buildertred app, I knew when people would be working and when all invoices were due. I know I’ll be calling them again for a future project."

"Very nice, professional guys to work with. For the kitchen remodel, I wanted to keep cabinet frames and countertop. It turned out nicer then I imagined!"

Terri Donahue

A kitchen remodel in New Hampshire by Oxland Builders with a mix of natural wood tones and bright skylights

What Our Clients Think

"The team at Oxland was excellent, very friendly, and professional. Working mainly with Rob as our point of contact, he made the whole experience easy by listening to what we were looking for and offering several potential solutions and ideas. As we were adding a new built-in buffet-style cabinet to an existing kitchen, the team at Oxland did an amazing job of ensuring everything matched up perfectly. We couldn't be happier with the look and quality of our new cabinet, and would highly recommend Oxland to others looking to have work done to their home."

Kirsten Larsen Schultz

Coastal-style home with a covered porch and classic architectural details, built by Oxland Builders in New Hampshire

What Our Clients Think

"Brad is an absolute jem. My husband and I were relocating from Brooklyn, NY to Newfields, NH. I called Brad to take a look at an old house we were interested in purchasing to let us know if he felt it was solid and what type of work would need to be done to it. Without even meeting me (only speaking to me over the phone) he was more than willing to help us out. He was honest, professional, thorough and polite."
