← All ADU models

A smart, self-contained home in your backyard — rental income, a private guest suite, or a quiet home office.

The Studio is the efficient one: one open, light-filled great room with a full kitchenette, a spa-style bath, and a sleeping nook — every square foot earning its keep. It's the fastest path to rental income on Oahu, and it lives far bigger than its footprint with vaulted ceilings and glass that opens to the yard.

What you get

  • Open great room + sleeping area
  • Full kitchenette — counter, sink, cooktop, fridge
  • Spa bath with glass walk-in shower
  • Vaulted ceiling + black-framed glass
  • Covered entry / lanai nook
  • Permitted & built to Oahu code

Investment & return

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

The unit — built & permitted
$275K–$325K
Standard to premium finishes. Includes design, DPP permit, and utility connections.
Designed yard & hardscape (optional · phaseable)
+ $45K–$85K
Pavers, planter walls, landscape lighting, landscaping, lanai & fire feature as shown in the photos.
Rent potential
$1,800–$2,600/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 →
