Partnering with Greenline West: Crafting Excellence at TNAH
For visionary designs, the right materials and partners are key. Greenline West was integral to TNAH, bringing Thermory’s top-tier materials to life with their expert execution.

We’re proud to have partnered with Greenline West, whose expertise helped make this year’s show home a stunning blend of innovation, sustainability, and timeless beauty.
“This year’s NAHB parade house is not to be missed. From the moment you enter, your senses are overwhelmed with warmth and comfort. The spectacular Clear Pine ceilings extend from the inside to outside to offer outdoor living and breathtaking views of the city. The rich Ash accent walls, custom shelves and benches provide the perfect contrast to the golden pine, and when combined with exotic veneers, transforms walls into art.”

A Bold Vision and Historic First
TNAH 2025 marks a historic first—it is the first 3-story home in the program’s history. This architectural feat includes a main level, an upper-level retreat, and a subterranean floor. Floor-to-ceiling windows capture breathtaking views of the Las Vegas Valley, seamlessly integrating indoor and outdoor living.
The main level is the heart of the home, featuring large common areas designed for entertainment and relaxation. The upper level offers a private sanctuary with luxurious bedrooms and en-suite bathrooms, while the subterranean level includes a wine room and corking parlor, perfect for intimate gatherings.
Designed to inspire, this home balances modern minimalism with bold, luxurious finishes. Current interior design trends—such as rich color accents, statement walls, and luxury finishes—are evident throughout the space, making TNAH 2025 a true showcase of what’s next in high-end residential living.
And, as always, TNAH isn’t just about aesthetics—it’s about performance. This year’s home meets the highest standards of energy efficiency and sustainability, aligning with certifications such as: National Green Building Standard “Emerald” Certification, ENERGY STAR Certification, Indoor airPLUS Certification, DOE Zero Energy Ready Home Program Certification.

Kitchen/Bar – The wet bar area is beautifully accented by a Clear Pine wall, complemented by chunky Ash shelves, adding depth and sophistication.
Primary Bedroom – A striking Vire & Wave feature wall, framed by an Ash border, transforms the fireplace wall into an elegant focal point, bringing warmth and movement into the space.
Curved Benches – Crafted by Accurate Millwork, the benches were meticulously constructed from 2×6 Ash, each piece precision-cut to achieve the custom profile. This careful design process resulted in comfortable works of art.
