Home Additions in Bellevue, WA

When you love your neighborhood but your home has started to feel a little tight, you do not always have to move. A well planned addition gives you the extra space you need while adding real value to your property. F&M Construction and Remodeling has been designing and building home additions for Bellevue families since 2010. As a licensed general contractor based in Bellevue, we handle the entire project, from drawings and permits to the final coat of paint.

Growing families, home offices, multigenerational living, and rental income are just a few of the reasons our clients choose to add on. Whatever yours is, we build additions that blend seamlessly with your existing home. Serving Bellevue and surrounding areas, we bring the local experience and craftsmanship that a project like this requires.

Home Addition Services for Bellevue Homeowners

Every addition is unique, and we tailor the design to match your home and your goals. Our home addition services include:

• Room additions and bump outs
• Second story additions
• Accessory dwelling units (ADUs) and detached units (DADUs)
• In law suites and multigenerational spaces
• Garage conversions and basement finishing
• Sunrooms, primary suites, and home offices

Adding an ADU or DADU is one of the smartest ways to create rental income or flexible living space in our region, but the rules can be confusing. Our guide on DADU regulations in Washington State breaks down what local homeowners need to know. If your project also involves updating the rest of the house, it pairs naturally with a whole home remodel.

From Permits to Finished Space

The hardest part of an addition is often the planning, and that is where having a true general contractor pays off. We handle design, engineering, and the permitting process across local jurisdictions, then manage every trade through construction. Because we understand how Eastside permitting works, your project moves forward with fewer delays and fewer surprises.

We also make sure your new space looks like it was always part of the home. Matching rooflines, siding, trim, and finishes takes skill, and our crews take pride in getting those details right. A well built addition should feel seamless, not bolted on, both inside and out, and that is the standard we hold ourselves to on every project.

What Does a Home Addition Cost in Bellevue?

The cost of an addition depends on its size, complexity, and finishes, along with any foundation or structural work involved. A simple bump out is very different from a full second story or a standalone ADU. Rather than guess, we assess your property, discuss your goals, and provide a detailed written estimate up front, so you can plan with confidence and no hidden costs.
