What We Build
Smart, seamless spaces—customized for comfort, function, and future value.
Room Additions
Extend your home’s footprint with a beautifully integrated living space. Whether adding a bedroom for a growing family or creating a flexible living area, we design room additions that feel like a natural part of your existing layout, with thoughtful storage, light flow, and architectural continuity.
Second Story Additions
Perfect for tight lots or preserving backyard space, second story additions offer major square footage without expanding your home’s footprint. We integrate new levels with structural precision and cohesive design, from staircase placement to roofing and siding finishes.
Home Offices & Flex Spaces
Create private, distraction-free zones for remote work or whatever fuels your next idea. From built-in cabinetry and custom desks to convertible layouts that evolve with your needs, we make these spaces highly functional without compromising style.
Primary Suite Additions
Add comfort and calm with a suite designed around how you rest, get ready, and recharge. Our suites often include spa-inspired bathrooms, spacious walk-in closets, and private patio access—crafted for relaxation and resale value.
In-Law Suites & Guest Units
Offer privacy and independence with separate living areas—ideal for extended family, guests, or long-term rental. We build everything from attached guest units to detached backyard studios, each designed with comfort, accessibility, and code compliance in mind.
Sunroom Additions & Enclosed Patios
Enjoy the outdoors all year with insulated sunroom additions, covered patios, or four- season rooms. These additions are perfect for lounging, entertaining, or creating bright transitions between interior and exterior spaces.
Why Choose a Home Addition?
More space. More comfort. More reasons to stay rooted.
A home addition offers more than square footage. It gives you the freedom to evolve your home instead of leaving it. And in high-value areas like San Jose and Palo Alto, building out or up is often the smartest way to invest in your property.
Stay in the location you love
Skip the stress of house-hunting, bidding wars, and moving costs.
Tailored to your lifestyle
Every design starts with how you live, and grows with your needs.
High return on investment
Room additions and second story builds often deliver 60–80% ROI in California markets, according to Remodeling Magazine’s Cost vs. Value Report.

Design Considerations
The details that make your addition feel like home.
Whether starting with a blank canvas or exploring home addition ideas, we guide every design
to feel well-integrated with your existing home while adding something new.
Architectural continuity
We match existing rooflines, exterior materials, and window styles to ensure your addition looks original, not tacked on.
Interior transitions
From flooring and trim to lighting and layout flow, we make new spaces feel naturally connected.
Popular finishes
Our clients often choose white oak flooring, quartz countertops, matte black fixtures, and warm neutral palettes for a modern-yet-timeless look.
California comfort
Sunlight, airflow, and outdoor connectivity are key. We often include large sliding doors, clerestory windows, and covered outdoor transitions that match the California lifestyle.
Energy efficiency
All builds include Title 24 compliance, high-efficiency insulation, and solar-ready infrastructure.
