Imagine having your own private backyard fishing pond with a built-in pier. For these Arlington, Tennessee homeowners, that setting became the starting point, shaping a home built around its lot in the verdant Cypress Lake community. From expansive layouts to large windows and bifold glass doors, every element supports a seamless indoor-outdoor lifestyle and effortless hosting.
At the center of it all is a four-season room that serves as a transitional space, connecting the home’s interior to its outdoor amenities year-round. Designed as a light-filled, flexible gathering space, it creates an indoor-outdoor environment for everyday living, entertaining, and everything in between.
“When we designed our home, we wanted to be able to entertain friends and family. At the same time, we wanted a space that could be used easily each day. We love that our NanaWall doors are so easy to open and close, meeting our needs. It makes entertaining much easier.” - Homeowner
Creating a Four-Season Room with Bifold Glass Doors
The Vision: A Space for Gatherings and Outdoor Fun
Tucked within a 14.05-acre site surrounded by mature trees and small, quiet lakes, the design maximizes its natural setting through expansive outdoor amenities and a strong emphasis on year-round indoor-outdoor living. Building on this relationship to the landscape, the homeowners, alongside builder The Dave Moore Companies and Shapiro and Company Architects, envisioned a four-season room that would act as a seamless extension of the outdoors.
“Our goal was to create a multi-season space that could be utilized for day-to-day or social events,” says The Dave Moore Companies. “By using NanaWall doors between both the house and the outdoor living area and the outdoor living area to the pool, we were able to give our customers the flexibility of using the space, no matter the weather.”
Amenities, Bifold Patio Doors, and Everything in Between
Mirroring the light-filled, breezy feel of California Rooms, the all-season living space is designed as a fully equipped extension of daily living and entertaining. A lounge area anchored by a fireplace and TV creates a comfortable gathering spot. Nearby, a kitchen zone includes a central island with bar seating, a refrigerator, and a pass-through window that connects directly to the main kitchen for easy serving and interaction. Overhead ceiling fans help maintain comfort and airflow throughout the space, enhancing year-round usability.
A Flexible Design Solution for Everyday Life and Entertaining
Key to achieving a true indoor-outdoor experience was the ability to fully open the four-season room to its surroundings while still allowing the home to feel more closed off when needed. To accomplish this, one NanaWall bifold glass door connects the main home to the four-season room, while two additional systems open the four-season room to the outdoors, linking the main home, the sunroom, and the outdoor living areas.
When closed, the interior system creates a quieter, more contained space, allowing the four-season room to be used separately for entertaining while keeping a visual connection to the rest of the home. When the interior bifold door is open, the space instantly becomes an extension of the home.
When the weather allows, and both interior and exterior bifold glass doors can be opened, the home fills with fresh air and natural light, delivering comfortable cross-ventilation and an easy flow from inside to out. Moving between the kitchen, sunroom, and outdoor areas feels seamless, making everyday living and entertaining feel more relaxed and connected.
“The bifold doors allow people to move easily from the house to the outdoor space during entertaining,” says the contractor. “The wall of doors that open to the pool deck allows our customer to have large functions with ease of flow from the house to the pool with no “traffic jams” in doorways.”
Generation 4 Bifold Glass Doors for Optimal Flexibility
Offering the slimmest frames on the market and smoothest operation, Generation 4 NW Aluminum 640 bifold glass doors were custom-built to complement the home’s minimal aesthetics and space dimensions. One five-panel, 16-foot-wide system connects interiors to the four-season room, while two seven-panel openings extend it to the outdoor areas.
A Low Profile Saddle Sill offers barefoot-friendly transitions between inside and out, while convenient swing doors in each system facilitate everyday use. To ensure year-round comfort, systems were specified with double glazed panels, supporting thermal performance while maintaining clean, open views of the surrounding landscape.
“The ability to reconfigure entertaining space in a matter of minutes is appealing to customers, along with the ease of doing so,” says the contractor. “Plus, the quality of the NanaWall systems meant virtually no maintenance required for our customers, which is a huge bonus in today’s world.”
