Reliable infrastructure
From electrical to plumbing to HVAC and gas lines, it’s crucial that your home addition has reliable, professionally-installed infrastructure.

Most popular types of home additions
Wondering what kinds of home additions are most common here in the Bay Area? Take a look at some of the most popular home expansion projects:
Room addition
Many families pursue a home addition because their current layout isn’t sufficient for their needs. Maybe, for instance, your teen is ready to stop sharing a room with a sibling. Or perhaps you need an at-home studio for your work-from-home job. From crafting rooms to nurseries to guest bedrooms, the extra space has so much potential!
Separate living quarters
Another common option for home expansion is to add on a separate living quarters, with all the amenities of an independent apartment. This kind of home addition will require plumbing, electric, and a kitchen (or kitchenette) set-up. This is a popular option if you’re planning on welcoming an older family member to move in with you or rent out a separate unit on your property.
Kitchen expansion
If cooking is something that you’re passionate about, or you’re simply tired of a cramped kitchen, expanding this area of your home is a great investment. Additions to your kitchen could include a walk-in pantry or extra floor space for a roomier cooking experience.
Sunroom or covered patio
Want to make the most of the sunny Bay Area days while enjoying all the comforts of home? A covered patio, sunroom, or attached greenhouse can give you the best of both worlds.
Garage expansion
Whether you want the space to park additional vehicles, install an electric charging station, or finally have that at-home mechanic set-up you’ve always wanted, a garage expansion is a popular choice for homeowners.
Laundry room addition
If your washer and dryer are taking up valuable floor space in your kitchen, a separate laundry room can make your home feel less cluttered. This is a great opportunity to include extra linen storage, space for ironing, or any other features to make laundry day a breeze.
