Home Additions in San Jose With Hanaray Construction's Addition Experts

Once upon a time you bought a home for your family in the San Jose, CA area. Since then, your family has expanded, leading you to outgrow your house. Instead of packing up your belongings and moving to a new neighborhood, consider a home addition from Hanaray Construction.

Why add on instead of moving?

A home addition allows you to stay in your neighborhood and keep the features you like about your home while changing the things you don’t. Whether it’s for your growing family or the family chef who craves more kitchen space, a custom designed addition will enhance the function, aesthetic, and market value of your home.

All projects are completed with the same award-winning service and value that our clients have come to expect.

Hanaray Construction's 10 Year Workmanship Warranty


At Hanaray Construction, we offer a 10 year Workmanship Warranty on all home addition work because we are confident in our teams’ building and remodeling expertise. If you find any issues, you can call us directly for immediate service.

Hanaray's Home Addition Services

Home Additions

Why move when you can add on? If you're running out of space in your home but love your house and neighborhood, then a home addition may be the answer for you. Whether its a bedroom suite, an in-law apartment, a new garage, a bathroom addition, or a kitchen expansion (or anything in between), we can do it!

Bathroom Additions

Want to enlarge your bathroom space or add another bathroom to your home but don't have room? A bathroom addition is a great option. A new bathroom brings added convenience for your family and can prove to be a valuable asset should you decide to sell your home in the future.

Garage Additions

A garage addition is a great way to add value to your home. Today, garage additions can offer much more than protection for your vehicles. Why not add an in-law suite, a man-cave, or home gym in the space above your garage? At Hanaray Construction, if you can dream it, we can build it!

Sunroom Additions

Looking to expand your home with a space with some flexibility? Sunroom additions allow you to enjoy the sunshine and outdoor air within the comfort of your home. Relax, entertain, and share special moments together with your family in a beautiful space that fits seamlessly with your home's interior and exterior.

5 Ways Hanaray Construction Stands Out

Reputation & Trust

Doing great work for our customers is what drives us. We've built our business since 2005 with pride, integrity and great customer service. Our customers are proof positive that the work you will see from us is high quality and first class. You will find our customers speak for our work with their testimonials.

Workmanship Warranty

You're making a big investment by choosing us to do your home renovations, and we want to make sure you know your investment is protected. At Hanaray Construction, we take a lot of pride in the quality of the work we do for our customers and we stand behind everything they build with a 10 Year Workmanship Warranty!

Quality Team

We only hire the best and most qualified employees to work on your project. If we wouldn’t want them in our home with our families, they don’t make the cut. All our employees also undergo a thorough background check before beginning work and we ensure that subcontractors are licensed and insured as well.

Licensed & Insured

In addition to providing quality work, we're fully licensed in the State of California, one of the most rigorous states in the country to obtain a license. Our insurance and workmans compensation insurance will also give you peace of mind to know that you are protected in the event of injury or accident on your property.

Cleanliness of Site

Remodeling can be a very messy undertaking. However, we protect the home from the front door to the work area with ZIPWALL dust barriers, paper and cardboard on the floors. We also use plywood on the lawns and driveway. We care about your comfort and we always strive to leave the home cleaner than we found it.

“Peter provided a quick bid for a whole hour remodel that turned out to be right on the money. His work is cost-effect, fast, high quality and delivery was on time. I am very happy with my experience with him. He minimized our dislocation as long as possible until bathrooms and kitchen had to come out. I would use Peter again and have referred him to friends a couple of times. Peter knows the city and inspectors and regulations. He gets things done!”
Brad Erickson - Campbell, CA
“Peter is great to work with! He is always on time and on site every day. He is a great listener and communicator. He gave me great guidance and advice re: acquiring appliances. He worked with the City to get all necessary approvals effortlessly. His prices are reasonable and the quality is superb. His bid was competitive and he came in at bid and on time. I was comfortable having him in my home when I was alone with my kids. I have referred Peter to friends and family.”
Mischa Hepner - Campbell, CA
“I have worked with Peter on numerous projects for the past ten years. Peter is the consummate professional. He is an experienced businessman and craftsman. My clients love the guy and give him numerous referrals. His communications skills are superb and his business practices are above reproach.”
