Inside Cullum Homes' Iconic Car Bars: Where Luxury Custom Homes Meet Automotive Art
When Modern Luxury Interiors featured Cullum Homes in its coveted Best of Design issue (Volume 1, 2026), it wasn't for a grand ballroom or a chef's kitchen — it was for an innovation that began, quite literally, by accident. The result? A signature feature that has redefined what luxury custom homes in Arizona can offer: the Cullum Homes car bar.
If you've been searching for a luxury home builder in Scottsdale or Paradise Valley that goes beyond the expected, Cullum Homes has been setting the standard since 1985 — and their signature car bars are just the beginning.
How Cullum Homes' Car Bar Concept Was Born
It started with unexpected soil. During site excavation at Cullum Homes' Village at Mountain Shadows development, engineers discovered the ground was softer than anticipated. Rather than viewing it as a setback, founder Rod Cullum — who established Cullum Homes with his wife Kim in 1985 — saw an opportunity: basements.
"Car bars originated in our Village at Mountain Shadows development almost by accident," says Rod Cullum. "The soil was softer than expected during site excavation, so we decided to take advantage of it and consider basements."
That single decision sparked one of the most talked-about lifestyle innovations in Arizona luxury real estate. Homeowners in Cullum's signature walkable neighborhoods expected estate-level living — including dedicated space to store, display, and enjoy their prized vehicle collections. The car bar was born to deliver exactly that.
What Is a Cullum Homes Car Bar? (And Why It's Nothing Like a Garage)
The term "garage" doesn't come close to capturing what a Cullum Homes car bar is. These are fully engineered, custom-designed automotive environments that function as immersive social spaces — part showroom, part lounge, part entertainment hub.
"Our signature car bars are fully immersive automotive experiences within the home," explains Lindsay Cullum-Colwell, Rod and Kim's daughter, who alongside her husband Paul Colwell is leading Cullum Homes into its next generation. "Cars become focal points, art pieces and part of the everyday experience."
Key features of a Cullum Homes car bar include:
Custom Car Lift Systems — Vehicles move seamlessly from traditional garage levels into dedicated display showrooms, allowing for dynamic, gallery-style arrangements.
Integrated Lounge & Entertainment Areas — Full bars, flat screens, lounge seating, and curated lighting transform the space into the home's most-used social room.
Collection-Driven Design — Every element, from carbon fiber accents to textural wallpapers, is guided by the aesthetic of the vehicles it houses.
Engineered Circulation — Meticulous planning ensures that cars can be repositioned safely and efficiently, even in spaces with rolling furniture platforms.
Luxury Custom Home Design That Reflects Your Collection
At Cullum Homes, no two car bars are alike — because no two collections are alike. The design process begins with understanding the vehicles themselves.
"Lighting and mood are critical," says Cullum Homes. "A classic collection versus muscle cars versus exotics would each guide us to a different aesthetic. From carbon fiber accents to textural wallpapers and integrated lighting, each collection of vehicles we design for informs a different direction."
This bespoke approach is a hallmark of everything Cullum Homes does. As one of Arizona's premier integrated design and construction firms, Cullum Homes manages architecture, interior design, and construction under one roof — ensuring that a car bar doesn't just look stunning, it works perfectly within the broader flow of the home.
From One Showpiece to Ten: Scalable Luxury at Every Level
Whether you're looking to spotlight a single prized vehicle or create a multi-car automotive gallery, Cullum Homes scales the concept to fit.
"We've ranged from a single vehicle feature to the capacity of 10," says Paul Colwell. Their upcoming model at The Phoenician — slated to open in summer 2026 — will showcase a car bar accommodating four to five vehicles, giving prospective buyers a chance to experience the concept in person.
In one memorable project currently under construction, Cullum Homes placed lounge seating on a custom platform fitted with concealed wheels. The furniture rolls away as vehicles are repositioned, then glides back into place to anchor a sophisticated entertainment space — complete with a full bar and large-format television. It's engineering and hospitality in perfect harmony.
Arizona's Most Exclusive Luxury Home Communities
Car bars are now a signature amenity across several of Cullum Homes' premier Arizona communities, including:
The Village at Mountain Shadows — Where the car bar concept originated

40 Years of Luxury Homebuilding Excellence in Arizona
Rod and Kim Cullum founded Cullum Homes in 1985 with a clear mission: to provide the finest homebuilding experience available. Four decades later, that mission remains unchanged — even as the next generation steps in.
"We believe our legacy for the future will remain what it is today," says Kim Cullum. "To provide the finest homebuilding experience for our clients."
Lindsay Cullum-Colwell and Paul Colwell are honoring that legacy while pushing it forward. "Modern luxury is about intention and integration," says Colwell. "Homeowners today are prioritizing spaces that support wellness, performance and balance." The car bar is a perfect expression of that philosophy — a space that integrates passion, beauty, and function into the fabric of daily life.
