Nanea III at Koa Ridge: Detached Homes with Real Yards — and Floor Plans You Can Customize

Nanea means tranquil, and Nanea III is the series Castle & Cooke builds for people who want room to spread out. These are detached single-family homes — no shared walls — sold as fee simple condominium units, with a two-car enclosed garage on every plan and private yard areas that have run from roughly 4,270 to nearly 7,800 square feet. That is a genuine single-family lot, and one of the very few places left on O‘ahu to buy new construction with a yard that size.

• 3 to 4 bedrooms standard, up to 6 with options; 1,314–2,228 sq ft
• Detached homes with two-car garages and private yards
• Structural options available to initial purchasers
• Estimated maintenance fee of $66.76 per month

The Largest Homes at Koa Ridge

Living areas run from 1,314 to 2,228 square feet across the A through F plan families. The Plan A series is the only single-story option, with a loft option that can add a second floor. The E series places a bedroom and full bath downstairs with family rooms on both levels — the multi-generational plan. The Plan F, at 2,228 square feet, is the largest home at Koa Ridge, with a downstairs bedroom, a great room and a separate living room, and four bedrooms plus family room and laundry upstairs.

Make the Plan Yours

This is what sets Nanea III apart from nearly all new construction on the island. Beyond finish selections at Castle & Cooke's Design Center, initial purchasers can choose structural options before the home is framed: enlarge the lānai, add an upstairs bedroom, convert a family room to a bedroom and den, add a second floor to the A2 plans, or relocate laundry to the garage. Several plans can be expanded to five or six bedrooms. The window closes as construction progresses, so knowing which homes are still open matters.

Every home is built in one of three exterior styles — Hawaiian Plantation, Craftsman, or Contemporary — assigned by lot, so the streetscape reads as a real neighborhood rather than a row of identical houses.

A Remarkably Low Carrying Cost

The developer's estimated monthly maintenance fee for Nanea III has been just $66.76 — a fraction of what the townhome neighborhoods at Koa Ridge carry, because there are no shared walls or corridors to maintain. Your yard and driveway are your own. Homes come with a solar hot water system, air conditioning in the main living areas and every bedroom, covered entry and lānai, and a ten-year limited warranty.

For Owner-Occupants — and the Prepared

Nanea III carries a twelve-month owner-occupancy covenant recorded against the deed. This is a place to live, not an investment property, and that is exactly why owner-occupant buyers get a real shot at these homes. Releases run on a chronological system — completed packets are ranked in the order they arrive — so preparation, not luck, determines what you get to choose from. Roughly 82 homes are planned across two phases, with Phase II construction underway and completion estimated on or before December 2026.
