The One-Bedroom

The sweet spot for ohana or rental — a true one-bedroom home with its own lanai, out your back door.

The One-Bedroom is the one most families choose: a private bedroom with a walk-in closet, a full bath, an open living-dining-kitchen with a real island, and a covered lanai to catch the trade winds. Room enough for parents, adult kids, or a premium long-term rental — with the privacy of a separate home.

Investment & return

Straight talk — most Oahu contractors hide their pricing. We won’t. Here’s an honest planning range to build The One-Bedroom on Oahu. Your exact price depends on your lot, utilities, and the finishes you choose.

The unit — built & permitted

$360K–$440K

Standard to premium finishes. Includes design, DPP permit, and utility connections.

Designed yard & hardscape (optional · phaseable)

+ $55K–$95K

Pavers, planter walls, landscape lighting, landscaping, lanai & fire feature as shown in the photos.

Rent potential

$2,500–$3,400/mo

A permitted ADU can cover much of its own financing — many pay for themselves in about 10–12 years.

Planning estimates for budgeting — not a quote. We’ll give you a firm, line-item price for your lot in your consultation, and we can walk you through financing.

Why build it with IBBUILDERS

Custom-built on your lot by a licensed Oahu general contractor (BC-39795) — not a mainland box shipped in a crate. We handle the DPP permit, the Hawaii build sequence, and the inspections, and you always know where it stands with a live project board and daily photo logs. Already pulled your own permit? We’ll take it over →
