Gregory Ain built it in 1953 for his own therapist: four bedrooms, two baths, three quarters of an acre, and a great room that ran the length of the house. In 2016 someone wrapped eight thousand more square feet around it. This is what happens to an Ain that nothing protects.
The Feldman House at 1181 Angelo Drive is the Gregory Ain that got away, and the story is not the one the architectural registry usually tells. It is not a rescue. Ain designed it in 1953 for Dr. Fred Feldman, who was his own therapist, and the family held it for six decades. Then it sold, and within two years it was the core of an eleven thousand square foot estate. As an architectural real estate agent in Los Angeles, Debbie Pisaro documents this house because of what happened to it, not in spite of it.
This is a registry entry and not a listing. Coastline 840 has never represented the property. The facts come from the public record, from the archive of Ain's commissions, and from the developer's own published account of the work.
The house Ain built
The Feldman House sits on three quarters of a wooded acre off Benedict Canyon, on a stretch of Angelo Drive that carries a Beverly Hills mailing address while sitting inside the City of Los Angeles. Ain built it in 1953, at the point in his career when the blacklisting had already closed the institutional doors and the residential commissions were what remained.
What he built was small by the standards of the address and characteristic of the man. Four bedrooms. Two baths. A great room that ran the entire length of the house. Walls of glass that made the wooded lot into the architecture. Wood floors, built-in bookcases, a two-car garage. The restraint was the point. Ain sized rooms to what they were for, and a house on a rich street in 1953 got the same discipline as a tract house in Mar Vista, which is the whole argument of his career.
The client makes it stranger and better. Dr. Fred Feldman was Ain's therapist. Whatever passed between them in that office, it ended with the architect designing the doctor a house, and the house staying in the family until 2011, when it moved into the Gwen Silman Feldman Trust. Six decades in one family is rare anywhere. On this street it is nearly unheard of.

2014: the listing that invited it
The house came to market in 2014 asking $4,700,000. It sold that June for $3,000,000. That is a million seven hundred thousand off the ask, and it is the number that decided everything after.
Read the listing copy from that campaign and you can watch it happen. It described the three quarter acre sanctuary, the walls of glass, the great room running the length of the house. And then it closed with this: a great opportunity to renovate and expand this soulful work of architecture.
That is not a criticism of anyone. It is an accurate reading of the market. The house was a 1953 four bedroom on a lot that could hold five times as much, in a zip code where land is the asset and the building on it is a rounding error. The listing said out loud what every buyer was already thinking, and it priced the house accordingly. Two point six million dollars of the ask came off, and the buyer who stepped in was not buying an Ain. He was buying three quarters of an acre with a soulful problem on it.
2016: eleven thousand square feet
The buyer designed and built an expansion, completed in 2016, that took the property to roughly 11,300 square feet. The developer's own account is careful and worth quoting fairly: the existing mid-century house was preserved and expanded without destroying the integrity of the original design, with the height and scale of the additions arranged to centralize the original structure and accentuate its dramatic roof and deep overhangs. Clear fir windows and doors carried over from Ain's design. The sloped roof and ceilings continued into the new work.
Take that at face value, because by the standards of what usually happens on Angelo Drive it is a considerate outcome. The original was not scraped. It was kept, and it was made the center of something roughly four times its size. The house sold again later that year, and was subsequently marketed as a seven bedroom, nine bath estate at $16,900,000.
So the arithmetic of the whole story is this. In 2014 the market paid $3,000,000 for an Ain on three quarters of an acre. Two years and eight thousand square feet later, the same address carried an ask of nearly seventeen million. Almost none of that is the architecture. Almost all of it is the land and the square footage, which is exactly what the 2014 listing understood when it wrote the word expand.
Nobody did anything wrong here. The house was not protected, the lot was worth more than the building, and the market did what the market does. That is the point. Designation is not sentiment. It is the only thing standing between a house and its own land value.
The Ain houses that come up rarely reach the open market first. Debbie hears about them early.
Ask about pocket listingsWhy this house is not a landmark
It is worth saying plainly, because the internet says otherwise. The Feldman House is described in several places as a designated Historic-Cultural Monument. No designation record supports that, and the house itself argues against it: a protected monument does not take an eight thousand square foot addition.
The confusion is easy to trace. On at least one widely copied page, the Feldman entry sits directly above a line reading Los Angeles Historic-Cultural Monument No. 840, which belongs to the Ernst House in Los Feliz Oaks, a different Ain entirely. One entry's credential migrated to its neighbor, and the claim has been repeated since. Anyone with a designation record for 1181 Angelo Drive is welcome to send it, and this page will change the same day.
The distinction matters more than a footnote. Ain's protected buildings are protected. The Mar Vista Tract is a Historic Preservation Overlay Zone, the city's first Modern one, and its owners are Mills Act eligible; Debbie profiles one of those houses in the registry. The Avenel Cooperative in Silver Lake is Historic-Cultural Monument No. 1221 and on the National Register. The Ernst House is Monument No. 840. Those buildings will still be those buildings in fifty years. Feldman had none of it, and Feldman is now the middle of an estate.
What an owner should take from this
If you own an undesignated house by a named architect, the Feldman House is your cautionary tale and your instruction manual at once. The threat is never a villain. It is arithmetic: the day the land is worth more than the building, the building is negotiable.
Three things move that math. Designation, which is slow, real, and carries the Mills Act with it. Documentation, because a house whose authorship is proved is a house a buyer can resell as an architectural home rather than a teardown. And representation that prices the architecture instead of the dirt, which is what pricing an architectural home in Los Angeles is actually about. The 2014 seller got $3,000,000 for a Gregory Ain. Whether a different campaign would have found a buyer who wanted the house rather than the lot is unknowable now, and it is the question worth asking before you list.

Frequently asked questions about the Feldman House
Where is the Gregory Ain Feldman House?
The Feldman House is at 1181 Angelo Drive, off Benedict Canyon, with a Beverly Hills 90210 mailing address on a stretch that sits inside the City of Los Angeles. It is a private residence and not open to the public, so please respect the owners rather than visiting.
Who did Gregory Ain build the Feldman House for?
Dr. Fred Feldman, who was Ain's own therapist. Ain designed the house in 1953, and the family held it for roughly six decades, until it moved into the Gwen Silman Feldman Trust in 2011. That length of single-family ownership is rare on any street, and unusual on this one.
What did the Feldman House look like as Gregory Ain designed it?
Four bedrooms and two baths on three quarters of a wooded acre, with a great room running the entire length of the house, walls of glass opening to the grounds, wood floors, built-in bookcases, and a two-car garage. Modest for the address, and characteristic of Ain's restraint.
How much did the Feldman House sell for in 2014?
It sold in June 2014 for $3,000,000 against an asking price of $4,700,000, a gap of $1,700,000. The listing described the property as an opportunity to renovate and expand, which is a fair reading of a 1953 four bedroom sitting on a lot worth considerably more than the house.
What happened to the Feldman House after 2014?
The buyer designed and built an expansion completed in 2016 that took the property to roughly 11,300 square feet. The developer's account says the original house was preserved and expanded rather than replaced, with the additions arranged to centralize the original structure. It sold again that year and was later marketed at $16,900,000.
Is the Feldman House a Historic-Cultural Monument?
No designation record supports that, despite the claim appearing in several places online. It appears to trace to a page where the Feldman entry sits directly above a line about Monument No. 840, which is the Ernst House in Los Feliz Oaks. A protected monument would not have taken an eight thousand square foot addition.
Which Gregory Ain buildings are actually protected?
The Mar Vista Tract is a Historic Preservation Overlay Zone, the city's first Modern one, which makes its owners Mills Act eligible. The Avenel Cooperative in Silver Lake is Historic-Cultural Monument No. 1221 and on the National Register. The Ernst House is Monument No. 840, and the Dunsmuir Flats are No. 954.
Does an addition ruin the value of an architect-designed home?
It depends entirely on the buyer. To someone buying the land, an addition adds value. To someone buying the architecture, originality is the asset and an addition is a subtraction. The two buyers pay very different prices, which is why who sees the listing matters as much as what it says.
How do you protect an architect-designed home from being expanded away?
Designation is the only durable answer, and it carries the Mills Act with it. Short of that, document the authorship so the house can be resold as architecture rather than as a lot, and use representation that prices the design instead of the dirt. The day the land outvalues the building, the building is negotiable.

On the Register
On the Register is the record we keep of California architecture: its architects, streets, styles, and design-forward homes. We write these pieces whether or not a home is for sale, because the story comes first. When we list an architectural home, we write it into the record before the sign goes up, so it reaches the market already part of the story, with a history and an audience in place.
