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.

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.

addition looks original, not tacked on. - Interior transitions
