Maintenance Free Ultrawood Material: The Denali collection is made of our composite material called Ultrawood. Ultrawood is a durable, heavy duty, ultra low-maintenance synthetic material that looks like real wood but will last much longer. Spacious Design: The Denali 16x24 is a multi-functional outdoor building with oversized windows to let in a lot of light and to provide excellent views. The Denali 16x24 is large enough to house either a swim spa or hot tub with room for steps and a sofa to relax around the swim spa or hot tub. The spacious design also allows for several other applications such as an employee lunch room or meeting room. Stylish Roof: The fashionable PC Duraflex ® roof and accompanied by transparent gables, provides a capacity rating of up to 40 lbs. per square foot. Sliding Windows: Comes with 8 Aluminum framed sliding windows with optional tempered glass. Customizable door placement: The entrances have been designed so they can be placed on any side of the gazebo for added convenience and flexibility. Lockable Aluminum Doors: A set of heavy–duty, lockable, aluminum French doors and a set of heavy–duty, lockable, aluminum Sliding doors provide added security and piece of mind. Upgrade Options: Add a screen kit, tempered glass or additional bracket support for increased wind and roof capacity rating to your gazebo or take advantage of our discount pricing by purchasing multiple upgrade kits.

Extra-Wide Modern Design for Swim Spas, Parties, and Year-Round Living
The Denali 16×24 takes the modern design language of the Denali collection and widens it to approximately 16 feet. That extra depth — compared to the approximate 14-foot width of the Denali 14×24 — creates a noticeably more spacious interior that accommodates activities requiring a wider footprint. Whether you are positioning a swim spa with full walk-around clearance on all sides, setting up a large party room with tables and seating, or building a multi-zone space with a hot tub on one side and a furnished lounge on the other, the approximate 16-foot width gives you room to do it properly.
One customer purchased the Denali 16×24 specifically for their swim spa and reported that it took only a couple of days to assemble. Friends and family who visited could not believe how good it looked — describing it as far classier than anything else they had seen. Another customer noted that their spa enclosure was exactly what they needed to use their swim spa year-round, protecting them from rain and cold. During a snowstorm, they sat inside the enclosure looking out at the falling snow, calling it a great experience.
Two-Tier Reinforced Roof for Heavy Weather
The Denali 16×24 features a two-tier Duraflex PC roof with reinforced truss supports. The approximate16-foot width creates a substantial roof span that requires engineered structural support to safely handle snow loads, wind pressure, and the accumulated weight of ice and rain over time. The reinforced truss system distributes these loads evenly, and the two-tier design adds interior ceiling height that makes the space feel grand and open.
Ultrawood Composite: The Permanent Outdoor Structure
Built from Ultrawood composite, the Denali 16×24 is a permanent structure that requires zero ongoing maintenance. No staining, no sealing, no repainting, no replacing rotted boards. At this size, the maintenance savings over a wood-framed building are dramatic: a 16-by-24-foot cedar or pine structure would require days of work and hundreds of dollars in materials every one to two years. With the Denali, that cost and labor drops to nothing. The Ultrawood material looks and feels like real wood but lasts indefinitely without degradation.
Dual Entrances and Customizable Layout
Two entrances — a set of aluminum swing French doors and a secondary sliding door — provide access from different sides. The standard configuration places the French doors at one end of the 24-foot front side and the sliding door directly opposite on the back side, but all positions are customizable during assembly. This is especially valuable for homeowners who need the primary entrance facing the house and a secondary entrance facing a pool, garden, or driveway.
Sliding lockable windows with optional tempered glass provide full-perimeter ventilation and security. Screen kits add bug-free airflow during warm months.
Foundation, Permits, and Assembly
A reinforced concrete pad is the recommended foundation for swim spa and hot tub use. Westview’s engineering stamp document provides resources for building permits and HOA approvals. Assembly takes approximately two days with three people. Outside wall dimensions are approximately 15.3 feet by 23.75 feet, so a 16-by-25-foot foundation provides comfortable clearance.
For an even larger structure, the Denali 16×28 adds four more feet of length and a third entrance. For a narrower footprint, the Denali 14×24 offers the same length in an approximate 14-foot width. Call 1-800-895-1972 to discuss your project.
