The Largest House in Alabama: Inside the $11.8 million Chateau Montagel 2026

I have walked through hundreds of luxury homes throughout my career as an architect. Grand foyers, sweeping staircases, imported stone  none of it surprises me anymore. But when I first came across Chateau Montagel in Shelby County, Alabama, I stopped scrolling. Even from aerial images, this place reads differently. It does not just feel large. It feels like it belongs on another continent entirely.

The largest house in Alabama sits at 7 Montagel Way inside the gated Shoal Creek community, about 30 minutes southeast of Birmingham. It covers roughly 54,000 square feet in the main structure alone and when you include its two guest homes, the total footprint stretches to approximately 68,000 square feet.

That puts it in the same conversation as some of the largest private residences in the entire United States. For context, the White House spans around 55,000 square feet. Chateau Montagel is bigger.

What Is the Largest House in Alabama?

The largest house in Alabama is Chateau Montagel, also widely known as “The Guitar House.” It is located at 7 Montagel Way in the Shoal Creek Golf and Country Club neighborhood of Shelby County, just outside Birmingham.

The estate ranks as the 44th largest home in the United States, according to public records cited at the time of its 2025 acquisition.

Where Is the Largest House in Alabama Located?

Chateau Montagel the largest house in Alabama sits at 7 Montagel Way inside the gated Shoal Creek Golf and Country Club in Shelby County, Alabama, roughly 30 minutes southeast of downtown Birmingham.

The estate stretches across 27 acres in the Appalachian foothills, surrounded by a Jack Nicklaus-designed championship golf course, private lakes, fishing docks, and scenic hiking trails. Few private addresses in Alabama match this location in size, exclusivity, access to nature, and proximity to a major city.

The Architecture: A French Château in the Alabama Hills

Birmingham architect Bill Sheppard designed the largest house in Alabama in a French château style, drawing direct inspiration from St. Petersburg’s Imperial Winter Palace now the world-famous Hermitage Museum. 

The result is a striking limestone and stucco exterior finished with a hipped slate roof and a signature domed cupola. John-Bryan Hopkins completed the interior detailing after Sheppard departed the project. The decorative work was executed by the same specialized restoration firm behind projects at Buckingham Palace and the Biltmore Estate.

Inside the Estate: Room by Room

The largest house in Alabama was designed for living and entertaining at an extraordinary scale. Here is what you find inside:

The Grand Foyer 

The Grand Foyer of the largest house in Alabama sets the tone from the moment you walk in. A double sweeping staircase with wrought-iron railings rises beneath a hand-painted frescoed ceiling supported by Corinthian columns. A massive crystal chandelier anchors the space. Polished marble floors and gilded molding line every archway. Achieving visual balance at this scale and ceiling height is a genuinely difficult residential design challenge and this foyer executes it well.

The Primary Suites 

 The largest house in Alabama includes two separate primary suites, each exceeding 3,500 square feet in total floor space. Both feature hand-painted murals, candle-style chandeliers, and raised black marble soaking tubs set beneath dramatic arched windows.

Gold-accented trim runs throughout each suite. The en-suite bathrooms are finished with Corinthian columns, imported marble floors and walls, and custom gold fixtures an atmosphere that feels far closer to a five-star European spa than a private home.

The Bedrooms and Bathrooms

 The largest house in Alabama contains 15 individually designed bedrooms and 22 full bathrooms spread across the main structure. Each bedroom is generously proportioned and finished with custom details throughout.

The bathrooms feature imported marble surfaces, bespoke tilework, and carefully chosen fixtures that complement the estate’s consistent European character. No two rooms across the property are identical every space reflects the same high standard of craftsmanship found in the grand formal rooms.

The Movie Theater

 Inside the largest house in Alabama seats 25 guests and features a 170-inch screen, a full ticket booth, tiered seating rows, and classic theater curtains at the front. Renaissance-style mythology murals painted by a European art firm cover the entire ceiling.

The decorative detail carries through the full entry passage as well. In both seating scale and overall finish quality, this room directly rivals a commercial professional screening room.

The Library 

The Library is one of the most carefully crafted rooms inside the largest house in Alabama. Dark wood paneling covers every wall, a vaulted frescoed ceiling rises overhead, and an intricately carved fireplace anchors the far end beneath a gold chandelier.

Achieving this level of handcrafted interior detail is rare in American residential architecture today it requires skilled artisans, premium imported materials, and a construction budget that very few private residential projects ever reach.

The Kitchen

 Inside the largest house in Alabama operates at a fully commercial level built entirely for large-scale event hosting, not for everyday family cooking. Professional-grade appliances, wide dedicated prep areas, and a service-focused floor plan all reflect the estate’s original purpose: a property designed to host hundreds of guests at once. In both function and physical scale, the kitchen resembles a hotel catering operation far more than a standard private home kitchen.

The Wine Cellar 

Inside the largest house in Alabama stores approximately 2,000 bottles and sits within a 17,000-square-foot basement built entirely for entertaining. The same level contains a ballroom and grand reception rooms with coffered ceilings and detailed gold molding.

A 12-cubicle home office wing occupies a nearby area. Every floor of the building connects through a full-height commercial-grade elevator running from the basement to the top of the structure.

The Grounds and Outbuildings

The 27-acre estate extends well beyond the main house and includes two guest homes, a 12-car attached garage, a resort-style outdoor pool with two cabana apartments and a waterfall, a carriage house, and a front fountain set in a formal terraced garden. The equestrian center modeled after the late Queen Elizabeth II’s royal facility features a 6-stall barn with stalls imported from England, plus indoor and outdoor riding arenas and fenced pastures.

A Complicated Sale History

The largest house in Alabama cost $26–30 million to build in 1997 but sold for under $4 million at auction in 2003. It was relisted at $17.9 million in 2011 and cut to $13.9 million by 2014. Multiple sale attempts failed between 2015 and 2016.

It finally sold in 2017 for $4.8 million, then again in 2025 at the same price a clear example of how ultra-luxury estates outside major global cities rarely recover their original construction cost.

The 2025 Sale: A New Era for Alabama’s Biggest Mansion

In late 2025, Sergei Kaminskiy founder and CEO of the San Diego-based Kaminskiy Group  saw the estate on Instagram and flew to Alabama within days. He purchased Chateau Montagel for $4.8 million in November 2025 and renamed it Chateau de Kaminskiy.

He has announced a multi-year, multi-million-dollar restoration covering the original gold-leaf accents, frescoed ceilings, structural repairs, and new additions including a world-class biohacking facility, professional gym, golf simulation room, and car showroom. Kaminskiy is personally overseeing the renovation and documenting it for his 4 million+ social media followers.

What is the worth of the Largest House in Alabama in 2026?

Despite costing $26–30 million to build in 1997, the largest house in Alabama sold most recently for $4.8 million in 2025. Shelby County’s last formal assessment valued it at $11.8 million.

The gap between build cost and market value reflects the enormous operating expenses annual water bills alone reportedly exceeded $64,000 the thin buyer pool for 68,000-square-foot estates, and the hyperlocal luxury market outside a major global city. Its architectural value far exceeds its transaction price.

Final Thoughts

Chateau Montagel is something genuinely rare in American residential architecture. The largest house in Alabama was built with the ambition and craft level of European royal palaces and it still delivers that impact today. Its new owner, Sergei Kaminskiy, is committed to a full restoration rather than demolition or neglect.

For anyone who cares about architectural heritage, that is the best possible outcome. Whatever Chateau de Kaminskiy eventually becomes, it will remain what it has always been: the largest house in Alabama, and one of the most extraordinary private residences in the entire American South.
