Types of Home Additions We Build
Master Suite Additions
Create the luxurious retreat you deserve with a master bedroom addition that includes a spacious bedroom, walk-in closet, and spa-like bathroom. Adding a master suite provides private space for relaxation while significantly increasing your home’s resale value. We expertly integrate new additions with your existing roofline, match exterior finishes, and ensure seamless transitions between old and new spaces.
Second-Story Additions
When lot size limits horizontal expansion, building up is the perfect solution. Second-story additions maximize your property’s potential without reducing yard space, making them ideal for Bay Area’s established neighborhoods. Our team manages all structural engineering requirements, foundation reinforcement, staircase design, and roofing modifications to create beautiful, functional upper-level living spaces.
In-Law Suites & ADUs
Provide comfortable, private accommodations for aging parents, adult children, or guests with dedicated in-law quarters. According to the California Department of Housing and Community Development, Accessory Dwelling Units (ADUs)—also known as granny flats, in-law units, or backyard cottages—offer an innovative solution for adding housing while potentially generating rental income.
Kitchen & Family Room Additions
Expand your home’s heart with a larger kitchen or family gathering space. Open-concept additions create flowing, light-filled areas perfect for modern living and entertaining. We handle everything from foundation work and framing to electrical updates, plumbing installation, and custom finishes that seamlessly match your existing home.
Home Office & Workspace Additions
With more professionals working from home, dedicated office space has become essential. A custom home office addition provides the quiet, professional environment you need while maintaining separation between work and home life. We design functional workspaces with proper lighting, electrical capacity for technology, and soundproofing considerations.
Sunroom & Four-Season Room Additions
Bring the outdoors in with a beautiful sunroom addition featuring abundant natural light and comfortable climate control. Perfect for enjoying pleasant California weather year-round, sunrooms add versatile living space for relaxation, dining, or indoor gardening.
Garage Additions & Conversions
Add protected parking, workshop space, or hobby areas with garage additions. Alternatively, we can convert existing garage space into functional living areas while adding new garage structures to maintain your parking needs.
Bathroom Additions
Reduce morning congestion and add convenience with additional bathrooms. Whether adding a powder room for guests or a full bathroom for a growing family, strategic bathroom placement enhances daily living and increases property value.

Benefits of Home Additions
Increase Property Value
According to the National Association of Realtors, well-executed home additions consistently rank among the top home improvements for return on investment. Quality additions can recoup 50-90% of their cost at resale, with master suites, bathrooms, and ADUs typically commanding the highest returns.
Avoid Moving Costs & Disruption
Expanding your current home eliminates the substantial costs and stress of relocating. You maintain your established neighborhood, school district, commute patterns, and community connections while creating the space you need. The emotional and financial costs of moving—realtor fees, closing costs, moving expenses, and home search time—often exceed the investment in a thoughtfully designed addition.
Customize to Your Exact Needs
Unlike buying a different house and hoping it meets your requirements, home additions allow you to create exactly what you want. Every detail—from room dimensions and window placement to storage solutions and finishes—can be customized to your specific lifestyle and preferences.
Maximize Your Lot's Potential
For Bay Area homeowners on desirable lots with great locations, schools, and neighborhoods, building up or out makes more sense than starting over elsewhere. Home additions let you fully utilize your property's potential while preserving everything you love about your current location.
Accommodate Life Changes
Growing families, aging parents moving in, adult children returning home, or new work-from-home needs—life evolves, and your home should evolve with it. Home additions provide flexible solutions that adapt to changing circumstances without requiring relocation.
