Expand Without Compromise.
Additions that look as though the house was always meant to be that way — matched in roof line, trim, and rhythm to the home you already love.
An addition should feel inevitable, not added.
The hardest thing about a home addition is making it disappear into the house. The roof pitch has to match. The trim profiles have to align. The new floor has to meet the old one without a transition strip — and the new ceiling has to feel like it was framed by the same hand.
Two decades of working on Maui's older homes has taught us to read existing construction the way a restorer reads a painting — and to add to it with the same respect.
A primary suite that completed a thirty-year-old home.
For a Lahaina family who had outgrown their original master, we added a 600-square-foot primary suite with a private lanai and a dedicated walk-in closet. The new wing reads as original construction — same plate height, same eaves, same plaster — and the family slept in their existing bedrooms every night of the project.
Three kinds of additions we know cold.
Most of our addition work falls into a few patterns — and we have refined each of them over many homes across the island.
Primary SuitesA retreat that earns its name.
Bedrooms, bathrooms, and quiet space designed as a true sanctuary inside the home — generous closets, soft natural light, and a walk-out connection to a lanai or garden whenever the lot allows it.
Family Rooms & Great RoomsMore room to be together.
Adding a great room is often the most transformative move a family can make. We re-engineer the connection to the existing kitchen, raise the ceiling where structure allows, and bring in light that changes how the whole house feels.
Ohanas & Second StoriesDensity, done with care.
Permitted ohanas, second-story additions, and detached studios — engineered for Maui's wind and seismic codes, designed to live well, and matched architecturally to the main residence so the property reads as one.
Roof lines, trim profiles, and the details that betray new work.
When an addition fails, it is usually because the new work fights the old. Eave returns are the wrong length. Trim profiles are close but not identical. Window mullions are a different proportion. Roof slopes are off by half a degree. Each small mismatch adds up to an obvious seam.
We measure, document, and replicate the existing house with obsessive precision — milling custom trim when stock no longer matches, sourcing windows that align with the originals, and confirming every detail with mockups before a single piece is installed.
The structural work no homeowner sees — and that's the point.
Tying a new wing into an existing structure is engineering work. We coordinate with the structural engineer, soils engineer, and Maui County permitting from day one, and we plan demolition so that load paths are continuous and lateral systems are upgraded where the addition triggers a code requirement.
Foundations are doweled. Existing roofs are opened cleanly. Electrical and plumbing services are upsized when the new load demands it. The result is an addition that performs as one home with the original — not two homes joined at a seam.
Most of our clients sleep at home every night of the project.
We engineer additions to be built from the outside in — framing the new wing, drying it in, finishing the rough trades, and only then opening the wall to the existing house. Dust barriers, separate access, and a clear daily schedule mean families continue to live in their home through almost every phase. The day we open the connecting wall is usually the only day daily life is interrupted at all.
Four phases, designed to protect daily life.
A clear path from first sketch to the night you sleep in the new wing — minimizing disruption to the home you already love.
Discovery
We walk the existing house with you, understand how the family lives, and map the addition that will resolve what the current home cannot.
Design
Architectural drawings, structural engineering, county-ready permit set, and a full line-item budget refined together before construction begins.
Build
Built from the outside in to keep the existing home livable. Daily site supervision, dust barriers, separate access, and weekly photo updates.
Reveal
A single connection day to tie new to old, then a meticulous punch-walk and one-year follow-up after the home has settled into its new shape.
An addition that will read as original to the next owner too.
Future buyers can spot a clumsy addition from the street. We design and build with the long view in mind — so that ten or twenty years from now, when the home eventually changes hands, the addition reads as original construction rather than as a project.
That discipline pays back in two ways: you get a home that feels whole today, and an asset whose value reflects the seamlessness of the work.
Wings, suites, and great rooms across Maui.
Each addition disappears into the home it joined — which is the highest compliment the work can earn.
"Friends still ask us when we are going to start the addition — and we have to remind them it has been finished for two years. That is exactly what we hoped for."
