Building a home on Oʻahu is one of the biggest projects of your life — and it should feel that way in a good sense, not a stressful one. IBBUILDERS takes new construction from raw idea to finished home under a single accountable team: design coordination, permitting with the City & County of Honolulu (DPP), sitework, and the full build, with a written scope and price up front and daily photos in your portal.
What we build
- Custom single-family homes
- Ground-up new construction on your lot
- Home rebuilds and full teardown-and-rebuild projects
- Multi-generational and ʻohana-style layouts
- Detached ADUs and second dwellings (see our ADU page)
- Structural, foundation, framing, and full finish work
Design, permits, and the paperwork
New construction lives or dies on the details before the first nail — zoning, lot conditions, utilities, engineering, and permits. We coordinate the design team, pull the required permits, and manage the DPP and HOA process so you’re not chasing agencies. You get one point of contact who owns the whole timeline.
What a new home costs on Oʻahu
Custom builds vary widely with design, site, and finishes, but as a ballpark new construction on Oʻahu typically runs from about $400 to $650+ per square foot. Because permitting alone can take many months here, most homes run roughly 12–20 months start to finish. We won’t quote a firm number or date until we’ve scoped your project fully — then it’s in writing.
Built for Hawaiʻi
We build for island living — the climate, the code, and the way local homes are actually used. Quality materials, honest timelines, and a 1-year workmanship warranty on everything we self-perform.
