Westview’s Largest Building: Designed for Swim Spas, Pools, and Grand-Scale Entertaining
The Brentwood 16×28 is the largest enclosed building that Westview manufactures in Ultrawood composite. At approximately 16 feet wide and 28 feet long, this is not a gazebo in the traditional sense — it is a full-scale enclosed structure large enough to house a swim spa or in-ground swimming pool, serve as an outdoor recreational room for a large family, or function as a private banquet hall for events and gatherings. The Brentwood 16×28 represents the top end of what is possible with a prefab composite building: commercial-grade size with residential-grade simplicity.
The oversized windows that define the Brentwood collection become truly spectacular at this scale. With windows wrapping the full perimeter of a nearly 450-square-foot structure, the interior is flooded with daylight from every direction. Customers describe the feeling as almost being outdoors — with full protection from weather, insects, and prying eyes. It is the largest room with a view in the entire Westview catalog.
Two-Tier Reinforced Roof with Truss Supports
The Brentwood 16×28 features a two-tier Duraflex PC roof system with reinforced truss supports. At this roof span, structural engineering is not optional — it is essential. The truss-reinforced design distributes snow and wind loads evenly across the structure, ensuring safe and reliable performance in heavy weather conditions. The two-tier roofline also creates an elevated interior ceiling height that makes the space feel appropriately grand for a building of this size.
Ultrawood Composite at Commercial Scale
The Brentwood 16×28 is built from Ultrawood, the same maintenance-free composite material used in every Westview model. At this scale, the benefits of Ultrawood over natural wood are amplified dramatically: imagine the cost and labor of staining, sealing, and maintaining a 448-square-foot wood-framed building every one to two years. With Ultrawood, that ongoing expense drops to zero. The material does not rot, crack, fade, or attract insects, and it never needs painting or sealing.
One customer who researched extensively before purchasing — comparing Westview to steel buildings, custom-built mini houses, open-air pergolas, and covered deck additions — chose the Brentwood because it offered superior quality at a fraction of the price of a contractor-built alternative. They noted that the building far exceeded their expectations and that the composite materials reminded them of Trex decking in quality and durability.
Three Entrances for Maximum Flexibility
The Brentwood 16×28 includes three separate entrances: one set of French double swing doors plus two sliding door entrances. The standard layout positions the swing doors on the 16-foot front side and both sliding doors on one of the 28-foot sides, but all door positions can be customized during assembly since the door and window wall sections share identical dimensions. This three-entrance layout is especially valuable for swim spa and pool house applications where separate access points for the wet area and the dry lounge area improve traffic flow and safety.
Foundation, Permits, and Assembly Planning
Housing a swim spa or hot tub in a structure of this size requires a reinforced concrete pad foundation engineered for the combined weight of the building, the water-filled spa or pool, and any furniture and equipment inside. Westview’s engineering stamped document provides resources for building permits and HOA approvals. Assembly takes a team of three to four people a full weekend. One customer reported that the crate was very large but that the contents were packed in layers for easy unloading, and the assembly instructions were great and easy to follow.
Optional screen kits, tempered glass window upgrades, and roof bracket reinforcements are available individually or as discounted bundles. Affirm financing is available at checkout. If a 28-foot length is more than you need, the Brentwood 16×24 offers the same approximate 16-foot width in a more compact format. Call 1-800-895-1972
I was able to install the hot tub enclosure myself with the help of a friend. The instructions were clear and easy to follow, and all the necessary hardware was included. It took us about half a day to complete the installation.
I was looking for a really beautiful gazebo to put on my back deck. all of the people I spoke with were extremely respectful polite and professional. I cannot recommend them enough.
Thanks so much for an amazing quality beautiful gazebo. Brent was a pleasure to deal with despite the delays related to covid interruptions on supply of materials. I couldn’t be more happy with the result and have already recommended the team to someone else I know.
Durable, complete instructions, simple step by step assembly. We plan on enjoying this gazebo for many years.
The gazebo looks great. Took 12 hours to put together, kids didn’t want to help. I’m glad I have a sturdy ladder to reach and support the roof sections during assembly. Directions were great which made for a simple step by step assembly. No parts were missing. I can’t recommend this gazebo enough. We use it with a fire table and a propane heater during this pandemic for get-togethers.
Beautiful gazebo! This gazebo is unbelievable! I ordered it online. It came out amazing. The company was fantastic and contacted me about when delivery would be here. The gazebo arrived in a timely fashion and was put together within three days. The gazebo is very sturdy and well-made. The parts fit together perfectly! It is better than expected! I live in the north east and was worried about the snow. This gazebo could handle plenty of snow! I would definitely recommend this gazebo to anyone. It is worth well more than I have paid.
After researching the internet for a suitable gazebo to store our swimspa, it was our decision to purchase from Westview. The company was very helpful and flexible in providing what we wanted allowing us to stay within our budget.
My wife and I ordered our Brentwood gazebo a few months ago and it just arrived. I did not realize how large the crate was that the gazebo was packed in. They packed the crate, a layer at a time so it was quite easy to remove all the parts, maybe no more than 1 hour. The assembly instructions were great, easy to read and follow, and my wife and I and our neighbors had it assembled in just over 6 hours. Now we are all inside sipping on some chilled wine and enjoying our new gazebo. There is so much room that my wife is going to buy more furnishings for it!
I live in a relatively small town with lots of historic buildings and I wanted a gazebo for my back yard that reflect this look and I found my Brentwood gazebo online from Westview Manufacturing. It took some time before it arrived, but I had my handyman and his helper all lined up to install it. It is now set up, and I am enjoying every minute that I am in it. I’ve have decorated it with lot of antique furnishings, and I love it. Thank you so much Westview!
I am a skeptic, or at least I was. Westview MFG has made me a believer, at least in them. I had been in the market for a gazebo for months, then a good friend of mine told me about Westview’s fantastic gazebos. At this time, I was still very skeptical, but after many calls to Westview with dozens of questions I finally took the plunge and purchased a Brentwood gazebo. I received it not long ago and assembled it and wow, what a great structure. Solidly built with great 90 degree angles, large windows, I think it’s just perfect. I am no longer a skeptic, at least not with Westview and their products. All I can say is Thank You!
I made a smart investment when I purchased my Brentwood gazebo from Westview MFG. It can get awfully cold up here in Illinois, so I had an electrician bring power into my gazebo. I hooked up a couple of infrared heaters and a couple of mini fridges. I had so much room, even with my hot tub on one side, that I bought a golf simulator and installed it in my gazebo. Yup, now I can golf inside when the weather is bad, and relax in the hot tub after a round. What does my wife think of this you might ask, well she loves golf too so we spend many a weekend in our new oasis golfing a few rounds.
