Brentwood 10x10

The Multi-Purpose Backyard Building with Oversized Windows

The Brentwood 10×10 is the most versatile enclosed outdoor building in the Westview lineup. While many Westview structures are designed primarily as hot tub enclosures, the Brentwood was built from the ground up to serve multiple purposes: a backyard studio for painting, music, or crafts; a garden office for remote work; a tea house or reading retreat; a guest house for visitors; or yes, a compact spa gazebo for a smaller hot tub or cold plunge tub. The oversized windows that define the Brentwood collection flood the interior with natural light and provide panoramic views of your backyard — creating a space that feels like being outdoors while being fully protected from the elements.

With interior dimensions of 108 5/8″ x 108 5/8″ (approximately 9 feet by 9 feet of usable floor space), the Brentwood 10×10 is a compact square building that fits easily into small and mid-sized backyards without dominating the landscape. The square footprint makes it exceptionally easy to position: it looks balanced in a corner, centered on a concrete pad, or placed alongside a deck or pool area.

Ultrawood Composite: Eco-Friendly and Maintenance-Free

The Brentwood 10×10 is constructed from Ultrawood, a high-quality synthetic composite material that looks and feels like real wood but requires zero maintenance. No staining, no sealing, no sanding, no painting — ever. Ultrawood is also environmentally friendly, made from composite materials that do not require the harvesting of old-growth timber. For homeowners who care about both aesthetics and sustainability, the Brentwood delivers on both fronts.

Like the Aspen and Colorado collections, featuring hip-style roofs with a central skylight, the Brentwood uses a clean roofline that gives the building a modern, architectural appearance. The Duraflex PC roof is engineered for heavy weather and provides year-round protection from snow, rain, and UV exposure.

Tempered Glass French Doors and Premium Window System

The Brentwood 10×10 comes standard with aluminum-framed tempered glass, double French doors — a premium feature that is an optional upgrade on many other Westview models. The tempered glass doors provide a clear, unobstructed view from inside the building and offer superior insulation, safety, and sound dampening compared to standard glass. Sliding windows with optional tempered glass upgrades wrap the remaining walls, giving you full control over ventilation and natural light.

This emphasis on windows and glass is what sets the Brentwood apart from every other collection in the Westview catalog. Where the Aspen and Colorado are designed as enclosed shelters first, the Brentwood is designed as a room with a view. If natural light and an open, airy feel are your top priorities, the Brentwood is the model to choose.

A Backyard Studio That Outperforms Anything a Contractor Can Build

One of the most common uses for the Brentwood 10×10 is as a backyard studio or garden office. Multiple customers have told us that they shopped local contractors who quoted them far more for a custom-built backyard structure that would not have been as well-designed or as maintenance-free as the Brentwood. One customer purchased the Brentwood specifically as a quiet space for reading and painting, noting that although most Westview buildings are designed for hot tubs, the Brentwood collection was recommended by the sales team and perfectly suited her needs.

The Brentwood 10×10 is also well-suited as a housing for a cold plunge tub, a small hot tub for 2-4 people, or a meditation and yoga space. The compact square layout creates an intimate, focused environment that works beautifully for personal wellness and creative activities.

Assembly, Upgrades, and Financing

The Brentwood 10×10 ships as a pre-assembled panel kit. One customer noted that while it is designed for two people, he was able to build it by himself, though having help with the rafters and roof panels is recommended. Assembly typically takes one day. Detailed instructions and toll-free support at 1-800-895-1972 are included. For homeowners in areas that require building permits, Westview’s engineering stamp document provides the resource you need for permit applications and HOA approvals.

Optional screen kits and roof bracket reinforcements are available individually or as discounted bundles. Affirm financing is available at checkout. If you need a larger multi-use space, consider stepping up to the Brentwood 14×24 for swim spa, entertainment, or commercial use. Call 1-800-895-1972 to discuss your project.
