Craftsmanship Meets Coastal Beauty: A Custom Kauai Home Featuring WindsorONE Trim
Nestled in the breathtaking Kukuiʻula community on the island of Kauaʻi, this stunning custom home by Kolea Construction is a masterclass in coastal luxury and craftsmanship. Designed to embrace the natural beauty of Hawaiʻi while delivering high-end finishes, the home features a full interior package of WindsorONE premium trim products — including shiplap ceilings and walls, door casings, and baseboards — all combining to create a timeless, cohesive look.
Bringing a Design Vision to Life
In a tropical environment like Kauaʻi, materials are constantly put to the test. High humidity, salt-laden air, and intense sun exposure can cause traditional trim products to warp, swell, or degrade over time. That’s why, Willis, at Kolea Construction chose WindsorONE Protected trim — engineered to perform in even the most demanding coastal climates.
The homeowners wanted a warm, inviting interior that still felt clean and architectural. By combining crisp WindsorONE WORS6 shiplap with smooth S4S and S1S2E boards, the team was able to deliver a classic, craftsman-inspired interior finish that’s both modern and timeless.
The Power of Protected Trim: Why WindsorONE Was the Right Choice

PROTECTS AGAINST ROT, INSECTS & MOLD
When building in a paradise like Kukuiʻula, durability and performance are non-negotiable. That’s where WindsorONE’s Protected product comes in. These boards are treated to the core with Tru-Core technology, giving the material a 30 year warranty against rot, insects and mold, making them ideal for tropical environments like Hawaiʻi.
Builders and designers choose WindsorONE not just for its structural integrity but for its exceptional finish quality. The boards arrive with a smooth, 3 coats of arcylic latex primer that’s ready for a flawless top coat — saving time on prep and delivering long-lasting results.
For this project, Kolea Construction utilized:
- WORS6 Shiplap for all ceilings and select feature walls
- Protected S4SSE Trim Boards for baseboards and architectural accents
- S1S2E Trim Boards for door casing and transition details
This combination allowed them to mix different textures and profiles while maintaining a unified look throughout the home.
Shiplap Ceilings: Adding Character from the Top Down
One of the most eye-catching features of the home is the use of WORS6 WindsorONE shiplap across the ceilings. Unlike standard beadboard or drywall, the WORS6 profile features a square-edged shadow line that gives the illusion of depth and dimension. It creates an elegant visual rhythm that draws the eye upward — making rooms feel larger and more refined.
Whether in the great room, the bedrooms, or the lanai-adjacent living spaces, the shiplap ceiling installation instantly elevates the ambiance. It’s a smart choice for high-end homes that want to evoke that breezy, island-inspired charm without going overly rustic.
Walls That Make a Statement
While shiplap is often reserved for accent walls, this home embraces it fully — bringing WORS6 shiplap down onto select interior walls for a seamless, wrapped look. The result is a clean yet textured aesthetic that gives each room an identity while reinforcing the home’s cohesive design language.
The vertical and horizontal runs of shiplap give the home variety and movement. With WindsorONE’s crisp edge detailing, the joints stay tight and the lines stay clean, even as the wood adjusts to seasonal climate changes. Nice work by Kolea Construction on those corners!
Baseboards and Casings: Finishing With Flair
No interior trim package is complete without well-designed baseboards and door casings. In this project, Kolea Construction opted for Protected S4S trim boards as baseboards, providing a sturdy and elegant border along the floor lines. The simplicity of S4S trim ensures it doesn’t compete with the shiplap above — instead, it frames each room with architectural clarity.
For the door casings, S1S2E trim boards were used, offering a slightly eased edge and a tailored look that ties everything together. The use of matching trim across windows and doors helps unify the home’s interior architecture and gives it a polished, magazine-worthy appearance. This style of casing is referred to as Builder’s Bungalow, you can find more examples of it in the WindsorONE Idea Gallery.

Built to Last in Kukuiʻula’s Coastal Climate
Kukuiʻula, located on Kauaʻi’s sunny South Shore, is one of the island’s most desirable neighborhoods. The area’s luxury custom homes are known for their open layouts, indoor-outdoor flow, and meticulous detailing. However, the island environment presents unique construction challenges — especially for woodwork and millwork.
That’s why WindsorONE is a favorite among Hawaiʻi builders. Manufactured in the U.S.A. using sustainably harvested radiata pine, these boards have a Gold Interior Air Quality Rating, while still being durable for use on the exterior. All WindsorONE boards are milled to tight tolerances and come pre-primed and protected with Tru-Core to protect against, rot insects, and mold. It’s is a trusted solution for builders like Kolea Construction who demand long-term performance without sacrificing style. (Shoutout to Honsador Lumber Lihue for supplying the material for this project!)
