You don’t need to move to get the luxury space you desire. Work with Fernandez Designs & Builders for inventive design that truly reflects your needs and wants.

We choose only the best materials, fixtures and finishes from select local suppliers, and install them with superior attention to detail. The result is a home addition that will match or exceed the quality of your existing home.

Expand Your Home

Moving in Silicon Valley is hard. High real estate prices, transaction fees, the permitting process, and the low housing inventory make it almost impossible to find the perfect home. But the good news is that you don’t need to! Our home addition plans and construction services help homeowners improve and expand their current homes in ways they never thought possible. Make your house more comfortable, more usable, and a better fit for the long term with our home addition and second story addition services.

Kitchen extensions: We expect much larger kitchens than builders used to plan for, probably because we’ve realized how important the room is in our daily lives. A kitchen extension is therefore a very common addition. You can also expand your kitchen into a neighboring room and then replace the room in an addition.

Second story additions: Adding a second story to your home is the best way to dramatically increase your square footage and living space. If your home has a partial second story you can also increase it to add that missing bedroom or bathroom, and to fix a narrowly sloped roof.

In-law additions: Adding a whole in-law suite can significantly boost the function of your home, making room for family or for renters. Usually these additions include a bedroom, bathroom, kitchenette and living space. We also design and build standalone accessory dwelling units.

Other room extensions: Any room that is too small or unusually laid out can be fixed with a home addition. You can also fix overall layout problems by adding new spaces, like full baths, laundry rooms, and home offices.

The Limits on Home Additions in San Jose

Unfortunately, it’s not always possible to expand your home in the way that you envision. Most cities in Silicon Valley, including San Jose, Campbell, Cupertino, and Mountain View, have limits on how far your house can expand into your front yard, or how closely it can approach the fences on your side and back yard. Other issues, like your utility connections, soil composition, and home foundation, can also create limits on what you can build and where.

The good news is that our team is always available to survey your property to determine your options. We provide free on-site consultations for all work, including second story additions, and our knowledge of local city restrictions and ordinances can help save you time and money.

Why Choose Fernandez for Your Home Addition?

We’re licensed and insured, but that’s just the bare minimum. How do we stand out from our competition and design and build the best home addition for you?

The right experience: Remodelers can’t start with kitchen remodels and expect to that to prepare them to create a luxury home addition. Unlike the competition, we have decades of experience completing large, complex, high-end home renovations, including complete builds. We know what it takes to deliver a quality home addition on time and under budget.

Three-year limited warranty: We stand behind our work for three years, even though most of the competition only offers one-year warranties. We know that’s not enough time for the home to settle or to ensure your complete satisfaction.

Add the most value: We are always focused on adding long-term value to your home. Work with us to explore how your home addition can significantly increase your property value as well as your quality of life.
