A Phillip Jon Brown modernist on one of four lots carved from Errol Flynn's ranch. The architecture, the ground it stands on, and what the record actually says about the year.
Flynn Ranch House A is a 5,700-square-foot modernist residence at 7740 Flynn Ranch Road in the Hollywood Hills, designed by Phillip Jon Brown, AIA. It sits on one of four lots carved from Errol Flynn's former ranch, and it is a private residence rather than a public landmark.
Some addresses carry a story before a single wall goes up. Flynn Ranch Road is one of them. The land near the top of the Hollywood Hills was once Errol Flynn's ranch, and decades after the actor's own house was gone the ground was cut into lots and rebuilt. The best documented of what went up is House A, a glass-and-volume home that trades on both its architecture and its Hollywood ground.
Debbie Pisaro has spent 24 years as an architectural real estate agent in Los Angeles, and houses like this one, real architecture on famous ground, are exactly what she specializes in. What follows is the architect, the Flynn history, what the house actually is, and the two places where the published record disagrees with itself, because on a house priced partly on provenance those are the parts that matter.
What is Flynn Ranch House A?
House A is a two-story, roughly 5,700-square-foot modernist home at 7740 Flynn Ranch Road, with four bedrooms and five bathrooms and public rooms that step across changing floor levels to follow the hillside. It was designed for privacy and for entertaining: a screening room built for 35mm projection, a wine cellar, and a pool and spa set into terraced patios.
The construction is steel frame, with louvers used across the elevations. Brown organised the plan on a diagonal axis rather than a rectilinear one, which is what gives the interior its multi-dimensional feel, and he set a horizontal living room against a vertical fireplace so the two read against each other rather than agreeing. An open bridge carries from the stairwell to the primary bedroom. Even the garage is architecture here: three cars, staggered rather than lined up.
The house reads as a series of volumes rather than a single box. Two-story public spaces and shifting floor elevations make the interior feel like it is moving with the terrain, and the main rooms turn toward the long views across the San Fernando Valley to the San Gabriel Mountains. The screening room dates the house in the best possible way, a purpose-built 35mm theatre from before streaming, a genuinely Hollywood amenity on genuinely Hollywood land.
1984 or 1987? The record does not agree
This page previously gave 1987 and stated it as settled. Crosby Doe Associates, the brokerage that specialises in architectural property and has handled this house, gives 1984. Their account also notes independently that a 2018 offering was the third time the house had come to market in thirty-four years, which back-computes to 1984 and corroborates their own date.
Two dated sources, one of them internally consistent, is enough to say 1984 is the better-supported year, and this page now leads with it. But a build year on a Hollywood Hills house is exactly the kind of figure that gets copied forward without checking, so the honest version is both numbers and the reasoning. The assessor record settles it in a transaction; nothing published online does.
A build year sounds like a fact and is often a claim. Where two credible sources disagree by three years, the number in the listing is whichever one the last agent happened to copy. Pull the assessor record before it goes anywhere near a valuation.

Join the list or call (310) 362-6429Is Flynn Ranch House A connected to Errol Flynn?
Yes, through the land rather than the building, and the connection is documented rather than folkloric. Crosby Doe describes the parcel as one lot of four carved from a former ranch that belonged to Errol Flynn. The actor built his hilltop retreat, Mulholland Farm, in the early 1940s; the original house is long gone; the ground was subdivided and rebuilt; and the road name preserves the link.
Mulholland Farm was one of old Hollywood's legendary houses, a private world at the top of the hills. After Flynn's death the estate passed through other hands, including the musician Ricky Nelson, and the original house was eventually lost. What remains is the land and the legend, and a house on one of those four lots inherits both.
That kind of provenance is not trivia. In the Hollywood Hills a documented connection to a figure like Flynn is part of what a buyer acquires, and it is one of the details worth documenting properly rather than gesturing at. The four-lot subdivision is the specific version of the claim, and specific claims are the ones that survive a buyer checking them.
Who is Phillip Jon Brown?
Phillip Jon Brown is a Los Angeles architect, trained at USC and MIT, known for modern houses that answer closely to their hillside sites and, more widely, as the architect of the Malibu house Dick Clark owned. Debbie keeps a full Phillip Jon Brown profile covering the arc of that career.
Building on a steep Hollywood Hills parcel is one of the hardest problems in residential architecture, and it is where an architect's skill actually shows. Brown's plan for House A turns the constraints of the site into the experience of the house: the diagonal axis, the stepped floors, the bridge, the volumes that open as you climb. Moving through the rooms means moving with the hill and toward the view. A lesser house on the same lot would have been flattened into a pad and a box.
It sits comfortably among the other architect-driven houses of the hills, from the Forrest Theriot House in Laurel Canyon to the Barragan-inspired Outpost Estates house, and the wider circle of Marshall Wilkinson designs in the same terrain. Debbie's seven iconic architectural homes in Los Angeles and the wider architectural homes collection put a house like this in context.
Hillside architectural houses often move before they ever reach the open market. Debbie Pisaro sees them first.
See pocket listingsHow often has the house changed hands?
Rarely, which is the point. Crosby Doe records the 2018 offering as only the third time the house had come to market in thirty-four years, and a sale following it in January 2019. This page previously stopped at a July 2014 listing and described the house as not currently on the open market, which means it was a full transaction behind and framed in language that expires.
The current owners are private individuals and this page does not name them or publish a number against their house. What is worth stating is the pattern: three offerings in three and a half decades on a documented architect-designed house on named ground. That is the scarcity a buyer is underwriting, and it is also why the useful move is to be known to the people who hear first rather than to watch the portals.
How do you buy an architect-designed home in the Hollywood Hills?
It means valuing the things generic listings miss: the quality of the design, the integrity of the original architecture, the provenance of the site, and how the house handles its hillside. These homes are priced against other authored houses, not the volume-builder spec mansion next door, and the best of them often trade quietly.
- Design integrity. How faithfully the house still reflects the architect's original intent drives value more than a recent cosmetic remodel does.
- The site and its story, documented. A parcel with real provenance is part of what a buyer pays for, and the operative word is documented. Ask which source the claim comes from.
- The right comparables. An authored house is measured against other architect-designed houses, a Koenig or a Lautner, not the block average.
- The basic facts, verified. Build year, permitted square footage, attribution. On this house two of those three are contested in print.
- Access to quiet inventory. Hillside architectural houses often sell off-market, which is where a pocket listing network earns its keep.
This is where representation pays for itself. Debbie Pisaro is a 24-year veteran, founder of Coastline 840 and a 2025 Inman Luxury Leader, and she keeps a working knowledge of the Hollywood Hills from the Outpost to Mulholland, including which houses might quietly come available. For a buyer who wants real architecture on real ground, that network is often the difference between hearing about a house and standing in it.
If you are earlier in the process, the architects guide explains how these properties are valued, Coastline 840's explainer on pricing an architectural home covers why they break the usual math, and the architectural homes specialist page sets out the terms. Debbie writes about design across the region, from Los Feliz architecture to the coast, and she is among the names owners weigh when they look for the best Los Angeles historic and architectural real estate agent.
Who designed Flynn Ranch House A?
Architect Phillip Jon Brown, AIA, who trained at USC and MIT and is also known for the Malibu house Dick Clark owned. He built House A on one of four lots carved from Errol Flynn's former ranch, using a diagonal plan axis and stepped floor levels to work with the hillside rather than flatten it.
What year was it built?
Most likely 1984. Crosby Doe Associates gives 1984 and separately notes that a 2018 offering was the third time the house had come to market in thirty-four years, which corroborates that date. Some sources, including this page previously, give 1987. The assessor record is the version that settles it in a transaction.
Is Flynn Ranch House A connected to Errol Flynn?
Yes, through the land. The parcel is one of four lots carved from a former ranch that belonged to Errol Flynn, whose hilltop retreat Mulholland Farm dated from the early 1940s. Flynn's own house is long gone and the ground was subdivided and rebuilt, but the road name preserves the connection.
Where is Flynn Ranch House A?
At 7740 Flynn Ranch Road in the Hollywood Hills of Los Angeles, on a hillside site with long views across the San Fernando Valley toward the San Gabriel Mountains. It sits on one of four lots subdivided from Errol Flynn's former ranch near the top of the hills, reached by a private road.
Has the house sold recently?
It was offered in 2018 and sold in January 2019, per Crosby Doe Associates. That offering was recorded as only the third time the house had come to market in thirty-four years. It is a private residence and the owners are private individuals, so this page does not publish a current valuation against it.
What are its features?
Roughly 5,700 square feet with four bedrooms and five bathrooms, steel frame construction with louvered elevations, a diagonal plan axis, two-story public rooms on shifting floor levels, a screening room built for 35mm projection, a wine cellar, an open bridge to the primary bedroom, a staggered three-car garage, and a pool and spa on terraced patios.
What was Mulholland Farm?
Errol Flynn's private hilltop estate in the Hollywood Hills, built in the early 1940s and one of old Hollywood's legendary houses. After Flynn's death it passed through other owners, including the musician Ricky Nelson, and the original house was eventually lost, leaving the ranch land that the Flynn Ranch houses now occupy.
Who is Phillip Jon Brown?
A Los Angeles architect trained at USC and MIT, known for modern houses that respond closely to difficult hillside sites and for the Malibu house Dick Clark owned. His work at Flynn Ranch is characteristic: a plan organised on a diagonal, floors that step with the slope, and volumes that open toward the view rather than fighting the terrain.
How do you buy an architect-designed home in the Hollywood Hills?
By valuing design quality, original integrity and documented site provenance over generic square footage, and by pricing against other authored houses rather than spec mansions. Verify the build year, the permitted square footage and the attribution before any of them reach a valuation. Many of these houses trade off-market, so access runs through relationships rather than portals.
