If you’ve ever wished your beach house could double as a life-size puzzle, this $10 million Tudor-inspired estate on Neptune Avenue might be the dream you didn’t know you had.
Sitting high above the Pacific with front-row sunset views, the 6,800-square-foot home looks like a classic oceanfront retreat — until you discover its hidden rooms and clever passageways.
Listing agents Kurtney Noonan and Brandy Nuschy of Compass say the six-bedroom estate lives much larger than it looks. Elegant wardrobes disguise doorways, mirrors open into attic suites, and an ordinary primary closet leads straight to a secret room with its own ocean view. By the time you’ve found them all, the home feels closer to 10 or 12 bedrooms than the six on paper.
Add in the fact that it sits on Encinitas’ most coveted street — on a parcel you couldn’t replicate under today’s coastal regulations — and you start to see why buyers are circling. As Noonan puts it, “It’s truly irreplaceable. You simply cannot recreate this size and scale right on the oceanfront anymore.”
A rare coastal parcel with history
The estate was the longtime home of Charles Marvin III, a founding board member of the Leucadia 101 MainStreet Association and the Encinitas Rotary.
Stretching from Neptune Avenue to the oceanfront, the property represents a type of coastal lot that can’t be rebuilt under current regulations — adding to its long-term value and rarity in the market.
A quick look at the estate
The $9,995,000 property at 200 Neptune Avenue has six ensuite bedrooms, six baths, and a two-bedroom guest house with its own kitchen and private entrance.
Multiple decks capture sweeping ocean panoramas, while a wind-sheltered courtyard with a wood-burning fireplace offers cozy alfresco dining. A rare five-car garage, vaulted ceilings, custom woodwork, and onyx finishes round out the details.
Interiors as rich as the Tudor exterior
Inside, the home’s craftsmanship matches its storybook façade. Rough-hewn stone fireplaces anchor the living spaces, hand-carved wood beams stretch overhead, and wrought iron accents frame open archways with a touch of old-world elegance.
Large picture windows keep the interiors bright and airy, balancing the rich textures with sweeping views of the Pacific. Every detail — from ornate light fixtures to custom millwork — feels carefully curated, making the interior as memorable as its turreted exterior.
Panoramic views from every level
Walls of glass frame the ocean from nearly every room. Whether you’re in the great room by one of the five fireplaces or stepping out onto one of several ocean-facing decks, the home delivers sunset vistas on demand.
Secret rooms hidden in plain sight
The home’s most intriguing feature is its network of hidden rooms. A door disguised as a mirror off the upstairs bonus room opens into a light-filled suite carved out of attic space, complete with sitting area and bathroom.
In the primary suite, walking through the closet reveals another tucked-away room with an ocean view — ideal as a small bedroom, reading nook, or retreat.
A courtyard built for year-round living
Unlike many oceanfront properties, this one includes a protected garden courtyard where wind isn’t an issue. A wood-burning fireplace anchors the space, making it a favorite spot for dining and entertaining even on breezier coastal evenings.
“Winchester house meets Narnia”
“This estate is as eclectic and captivating as the community itself — think Winchester House meets Narnia,” agent Kurtney Noonan says. “Elegant wardrobes conceal secret rooms, hidden passageways lead to unexpected spaces, and every corner inspires wonder while delivering comfort and luxury. Soaring vaulted ceilings, bespoke woodwork, dramatic walls of glass, and a wind-sheltered courtyard with a wood-burning fireplace make it as functional as it is enchanting.”
“Add in a designer-curated two-bedroom guest house and a rare five-car garage, and you have a one-of-a-kind coastal treasure,” the listing agent added.
Guest house with designer touches
The separate two-bedroom, two-bath guest house has been fully updated with a sleek kitchen and its own ocean views, making it perfect for long-term visitors or multigenerational living. A private entrance ensures complete independence from the main home while still feeling part of the estate.
Set on Neptune Ave, the crown jewel of Encinitas
With its enviable location lined with million-dollar mansions, Neptune Avenue has long been considered one of Encinitas’ most coveted addresses. Running along the bluffs of Leucadia, it offers oceanfront privacy while keeping homeowners just steps from the lively shops, restaurants, and cafés of downtown.
With strict coastal regulations limiting new construction, parcels like this one — stretching from street to sea — are exceptionally rare. For buyers, that combination of walkability, panoramic views, and long-term value makes 200 Neptune Avenue a rare trophy asset for the right buyer.
