More space. More of the home you love.
Room additions, ADUs, second-story builds, and garage conversions — engineered to feel like part of the original home, not bolted on after the fact.
Outgrowing your home doesn't mean you have to leave it. With property values where they are — and the homes you actually love hard to come by — adding to what you already own is often the smartest move you can make.
Our expansion work covers the full spectrum: a new bedroom for a growing family, a detached ADU that pays for itself, a second story that doubles your footprint, or a garage converted into rental income or a home office. We engineer each addition to integrate cleanly with the existing structure, roof line, and finishes — so the result reads as one cohesive home.
Expansions touch nearly every system in your house: foundation, framing, roofing, electrical, plumbing, HVAC, and finishing. We coordinate all of it under a single team, with the permit work, structural engineering, and inspections handled in-house.
Every kind of square-foot you can add.
Whether the goal is more living space, an income unit, or a future-proofed family home, we'll match the right kind of expansion to the right kind of property.
Room Additions
Bedrooms, bathrooms, family rooms, and home offices added to existing footprints — designed to flow naturally from the existing house.
- Bedroom & bathroom additions
- Bonus rooms & home offices
- Sunrooms & enclosed patios
ADUs (Accessory Dwelling Units)
Detached or attached secondary units built to current code. Ideal for rental income, multigenerational living, or future flexibility on the property.
- Detached & attached ADUs
- Rental-ready full builds
- Code-compliant from foundation up
Garage Conversions
Transform an underused garage into a livable studio, in-law suite, gym, or office. Insulation, HVAC, plumbing, and finish work brought to full residential standard.
- Studio & in-law conversions
- Home office & gym buildouts
- Full plumbing & HVAC integration
Second-Story Additions
When the lot can't grow outward, we build upward. Engineered second-story expansions that double usable space without sacrificing yard or character.
- Structural engineering coordination
- Roof reframing & integration
- Stairway & egress design
Expansion projects, simplified.
Adding to an existing home means working through zoning, permits, structural engineering, and trade coordination. We handle every stage so you're never the one chasing the city.
Feasibility Review
We assess the lot, zoning, setbacks, and structural conditions to confirm what's possible before you invest in design.
Plans & Permits
Architectural plans, structural engineering, and full permit submittal. We work directly with the city until approval.
Foundation & Framing
Demolition where needed, foundation, framing, roof tie-in, and rough mechanicals — built to integrate seamlessly with the existing home.
Finish & Hand-Off
Drywall, finish carpentry, paint, fixtures, and final inspections. Move-in ready when we hand over the keys.
Building onto a home is harder than building from scratch.
Existing structures hide surprises. Walls aren't always plumb, foundations age unevenly, and original wiring rarely meets current code. Expansions reward experience — and punish guesswork.
-
01
Structural-first thinking
Every expansion starts with a structural assessment of the existing home — not a leap straight into design.
-
02
Permit-savvy from day one
We know what each city will and won't approve, which saves months in revisions and resubmittals.
-
03
Seamless integration
Roof lines, exterior finishes, interior trim, and floor heights matched so the addition reads as original construction.

ADU & rental expertise
We've built income-ready ADUs across CA and TX — including the layouts, finishes, and meter separations that actually rent.
Most expansion projects require stamped architectural and structural plans. We coordinate with licensed architects and engineers as part of the project — you don't need to find one separately.
Room additions typically take ten to sixteen weeks of construction. Full ADUs run sixteen to twenty-four weeks depending on size and finishes. Permitting time is separate and varies by city.
In most California and Texas markets, yes — and many ADUs also generate rental income that offsets the build cost over time. We can share local examples during consultation.
Yes, when done properly. A code-compliant conversion includes insulation, ventilation, egress windows, plumbing where needed, and full electrical updates. We handle the permitting end-to-end.
ADUs typically tie into existing utilities, with separate sub-meters where rental tenants are planned. We coordinate with utility providers as part of the project.
