The Only Surviving Wallace Neff Dome House in the US Just Listed in Pasadena and We Wouldn’t Change a Thing

PTL — the Wallace Neff Shell House was meticulously restored by its current owners to preserve Neff’s original architectural intent, and we wouldn’t change a single thing.

1097 S Los Robles Avenue in Pasadena, California is widely recognized as the only surviving Wallace Neff Airform house in the entire United States. Built in 1946, it was wildly controversial in conservative Pasadena when it first appeared — a concrete dome, on a corner lot, in a neighborhood of traditional homes. But it has stood the test of time, has been beautifully and lovingly restored, and is now listed for $1,950,000.

Oh, and it has a rare Airform-constructed bomb shelter approximately 15 feet below the studio. We’ll get to that.

How Do You Build a Dome House?

Great question — here’s how it works. You erect an inflatable balloon in the shape of the home, then spray it with gunite (a type of sprayed concrete). The gunite cures around the balloon’s form, and when the balloon is deflated and removed, you’re left with a monolithic concrete shell. It is economical, remarkably strong, and unlike anything else being built at the time. Wallace Neff — one of California’s most celebrated architects — developed this Airform method in the 1940s believing architecture could be all three things at once: economical, resilient, and profoundly modern. Several were built. This is the only one left.

Life Inside the Dome

Beneath the curved shell, the living space is genuinely wonderful. A circular living room radiates from a central fireplace, flowing into the kitchen and bath. The home’s monolithic form blurs the line between structure and sculpture — it is a piece of art you can also live in. High ceilings, French doors, custom built details, and a warm efficient layout make it far more livable than you might expect from the outside.

The property also includes an over 1,000 square foot detached artist’s studio with a large open space, bath, and separate bedroom, with ADU plans already submitted to the city.

The Bomb Shelter

Added in the 1960s during the Duck & Cover atomic bomb scare days, the shelter sits approximately 15 feet below the studio and was reportedly designed to accommodate a family of four to five people based on standards established by the Office of Civil Defense. It is — and this is the listing’s own description — a “rare Airform-constructed bomb shelter.” Even the bomb shelter is Airform. Of course it is. The listing suggests it has potential to become a world class wine cellar, and we are fully on board with that vision.

The Only One Left

We look at thousands of homes. We have never seen anything quite like this one. A certified piece of American architectural history, lovingly restored, on a sunny corner lot in Pasadena, with a 1,000 square foot artist’s studio and a Cold War Airform bunker 15 feet underground. $1,950,000.

We wouldn’t change a thing either.
