A newly listed $12.98 million estate at 20388 Hill Avenue brings contemporary architecture, nine bedrooms, resort-style grounds and a private guest house to Saratoga’s prestigious Montalvo neighborhood.
A gated contemporary estate in Saratoga’s prestigious Montalvo neighborhood is back on the luxury market with a $12.98 million asking price, bringing nearly 7,500 square feet of newly built living space to one of Silicon Valley’s most closely watched residential enclaves.
Located at 20388 Hill Avenue, the three-level home stands on approximately 1.162 acres, or 50,617 square feet, near the intersection with Montalvo Road. The property contains nine bedrooms, nine full bathrooms, two half bathrooms, and a three-car attached garage. It was completed in 2025 and is being represented by David Welton of Compass under MLS listing ML82053736.
We find more than sheer size behind the price. The estate combines walls of glass, high ceilings, extensive outdoor entertaining areas, a wine cellar, a fitness space, a pool and spa, and a separate one-bedroom guest residence positioned beside the swimming area. It is a home designed to operate as a private retreat while remaining large enough for extended family, guests, and formal entertaining.
Saratoga Montalvo Estate at a Glance
The $12.98 million price works out to approximately $1,732 per square foot, placing the property firmly within Saratoga’s uppermost luxury tier. For context, the city’s median home sale price was approximately $4.1 million during the three months ending in May 2026. The Hill Avenue estate is therefore priced at more than three times the citywide median, although its scale, recent construction, and extensive amenities make it an unusual comparison with a typical Saratoga sale.
A Three-Level Contemporary Home Built Around Light and Scale
The home’s architectural identity begins with its emphasis on openness. According to the listing, the residence was designed around natural light, large interior volumes, and a close connection between the indoor rooms and surrounding gardens.
Walls of glass establish long views across the landscaped property while drawing daylight deep into the home. High ceilings add vertical drama, and a mix of hardwood, stone, and tile flooring gives each room its own visual character without disrupting the contemporary design.
We also see a practical division of space across the estate’s three levels. The main house contains eight bedrooms and 10 bathrooms, while the poolside guest residence adds a ninth bedroom and another full bathroom. That arrangement allows visitors or extended family members to stay near the main home without occupying its primary private quarters.
The central entertaining spaces include a formal entrance, a great room, a formal dining area, and a kitchen-family room combination. A separate family room provides an additional gathering area, allowing the estate to accommodate both large social events and quieter everyday routines.
The floor plan also includes a private office, utility room, dedicated laundry room, fitness area, and temperature-controlled wine cellar. These spaces reduce the need to convert bedrooms or informal living rooms into work, storage, or wellness areas.
The Kitchen Serves as the Home’s Social Center
At the heart of the residence is a large kitchen designed for daily meals and formal entertaining. Quartz countertops, an oversized island, and a breakfast bar create several areas for preparation, dining, and conversation.
The appliance package listed for the home includes a gas cooktop, double ovens, dishwasher, freezer, refrigerator, and garbage disposal. An additional built-in barbecue supports outdoor cooking and poolside events.
Rather than isolating food preparation behind walls, the kitchen connects with the family living space. This layout allows hosts to remain involved with guests while meals are being prepared. It also gives the home a more relaxed rhythm than a strictly formal floor plan might provide.
Dining options extend beyond a single room. The residence includes a formal dining area, an eat-in kitchen, breakfast seating, and outdoor terraces. A buyer could therefore move naturally between casual family breakfasts, indoor dinner parties, and evening meals beside the pool.
A Primary Suite Designed as a Private Retreat
The primary bedroom suite occupies one of the home’s most secluded spaces. It includes its own fireplace, a substantial walk-in closet, and a large bathroom designed to deliver a spa-like experience.
The primary bathroom combines a freestanding soaking tub with an oversized shower and dual sinks. Stone and tile finishes continue the material palette used throughout the residence, while the room’s dimensions create space for movement rather than tightly packing each feature.
The fireplace adds another layer of privacy and comfort. Instead of functioning only as a place to sleep, the suite can operate as a self-contained retreat within the larger estate.
Additional bedroom suites give family members and guests access to private bathrooms without sharing heavily trafficked spaces. The number of bedrooms also creates flexibility for nurseries, study rooms, private sitting rooms, or additional home offices.
Resort-Style Pool, Spa, and Outdoor Kitchen
The grounds are among the estate’s defining attractions.
The in-ground swimming pool and spa sit within a series of landscaped terraces intended for recreation, outdoor dining, and entertaining. Large paved areas provide space for lounge furniture, dining tables, and gathering zones without overwhelming the surrounding gardens.
An outdoor kitchen and built-in barbecue allow meals to be prepared without moving repeatedly between the pool area and the main kitchen. This feature is particularly valuable in a home where outdoor entertaining appears to be a central part of the design.
The listing also describes extensive landscaped gardens, fenced grounds, and gated access. Together, these elements give the property greater visual privacy while creating distinct outdoor areas for swimming, dining, walking, and relaxation.
The relationship between the house and pool is reinforced by the glass-heavy architecture. Indoor living areas appear designed to look toward the terraces and water, making the exterior feel like a continuation of the interior rather than a separate backyard feature.
A Poolside Guest House Adds Valuable Flexibility
One of the property’s most useful features is its one-bedroom, one-bathroom guest residence with direct access to the pool area.
Although it contributes to the estate’s total nine-bedroom count, the guest house functions separately from the eight-bedroom main residence. This creates options that a conventional guest room cannot easily provide.
It could accommodate visiting relatives, adult children, long-term guests, household staff, or a live-in caregiver. It may also serve as a private work or creative space, subject to local regulations and the buyer’s intended use.
Its position near the pool is particularly notable. Guests can enter the outdoor entertaining area without passing through the main residence, improving privacy for both visitors and permanent occupants.
We should distinguish the verified listing language from broader marketing descriptions. The MLS information identifies the structure as a guest house. Buyers interested in using it as an accessory dwelling unit or for rental purposes would need to confirm its permits, legal classification, and permitted uses independently.
Privacy Begins at the Gated Entrance
Luxury properties often promise privacy, but the physical arrangement of this estate appears to make it a central design feature.
The house sits behind a security gate on more than an acre of fenced land. Its location on a tranquil residential street limits the sense of exposure that can affect large homes positioned directly along busy roads.
The attached garage accommodates three vehicles, while an electric gate and a garage door opener provide controlled access. The combination of gated entry, substantial lot size, fencing, and landscaping creates several layers between the residence and the street.
That separation matters in a contemporary glass house. Large windows can increase natural light and strengthen outdoor views, but they can also make privacy more difficult. The estate’s lot dimensions and landscaping help support the open architecture without leaving the principal rooms directly exposed to public view.
Why the Montalvo Neighborhood Commands Attention
The Montalvo area takes its name from the historic Villa Montalvo estate, now known as the Montalvo Arts Center. The cultural property occupies more than 100 acres in the foothills above Saratoga and includes woodland trails, formal gardens, performance spaces, and the Mediterranean-style villa built for former U.S. Senator James Duval Phelan.
The villa’s original grounds were designed by John McLaren, the landscape architect associated with San Francisco’s Golden Gate Park. Phelan later directed that the estate be preserved for public use and the advancement of art, literature, music, and architecture.
That cultural landmark gives the surrounding neighborhood a character that differs from many newer Silicon Valley luxury developments. Montalvo combines wooded foothill scenery, estate-sized parcels and proximity to Saratoga’s historic center.
The City of Saratoga describes its downtown district, known as The Village, as a destination for restaurants, independent shops, and historic buildings dating from the late 1800s and early 1900s. The city is also home to Hakone Estate and Gardens, one of the oldest Japanese estates and gardens in the Western Hemisphere.
For buyers considering 20388 Hill Avenue, the location offers more than residential prestige. It places the estate near established cultural, recreational and commercial destinations while preserving the calmer atmosphere associated with Saratoga’s foothill neighborhoods.
Saratoga Schools Remain Part of the Location’s Appeal
The MLS identifies the property as being within the Saratoga Union Elementary School District and the Los Gatos-Saratoga Joint Union High School District. Nearby schools listed for the address include Saratoga Elementary School, Redwood Middle School, and Saratoga High School.
Saratoga Union School District operates three elementary schools and one middle school, serving approximately 1,600 students from transitional kindergarten through eighth grade. The district states that students living within its boundaries attend Redwood Middle School for grades six through eight, although individual elementary placement can depend on district procedures and available enrollment.
School boundaries, enrollment policies, and availability can change. Prospective buyers should verify current eligibility directly with the relevant districts rather than relying solely on real estate marketing materials.
The $12.98 Million Price Reflects a New Listing Strategy.
The property’s market history adds important context to the current asking price.
An earlier MLS entry marketed the estate at $14.88 million in January 2026. The price was reduced to $13.98 million in March before that listing was withdrawn in late June. A new MLS entry appeared on July 9 at $12.98 million.
That reduction represents approximately $1.9 million, or about 12.8 percent, from the January asking price.
The change does not establish the property’s final market value. A listing price remains an offer to sell, not evidence of what a buyer will ultimately pay. However, the new figure positions the estate more competitively among Saratoga’s active ultra-luxury listings.
Current nearby luxury inventory includes a newly constructed 5,212-square-foot property asking $10.95 million, a 5,500-square-foot hillside estate asking $14.88 million, and an approximately 10,024-square-foot Saratoga property asking just under $19 million. These are not direct valuation comparisons, but they demonstrate the broad price range occupied by large Saratoga homes.
What the Asking Price Buys at 20388 Hill Avenue
At nearly $13 million, the estate is targeting a narrow group of buyers. The strongest elements of its value proposition are not concentrated in one dramatic room. They are distributed across the entire property.
We see a combination of features that would be difficult to reproduce quickly:
- New construction completed in 2025
- Nearly 7,500 square feet across three levels
- Nine total bedrooms and 11 bathrooms
- More than one acre of landscaped land
- A separate poolside guest residence
- Gated and fenced grounds
- A swimming pool and in-ground spa
- Outdoor kitchen and built-in barbecue
- Private office and fitness area
- Temperature-controlled wine storage
- Three-car attached garage
- Contemporary architecture with extensive glass
- Location within Saratoga’s Montalvo area
The estate is therefore being marketed not simply as a large house, but as a complete residential compound. It offers private accommodation, recreation, workspace, wellness facilities, and entertainment infrastructure within one gated property.
A Modern Counterpoint to Traditional Saratoga Estates
Many of Saratoga’s best-known luxury homes draw inspiration from European villas, traditional California estates or Mediterranean architecture. The Hill Avenue residence takes a different direction.
Its contemporary form, expansive glass surfaces, and cleaner interior lines appeal to buyers who prefer new construction over a historic or heavily renovated property. The home does not attempt to reproduce the style of Villa Montalvo. Instead, it creates a modern architectural counterpoint to the neighborhood’s older landmarks and established gardens.
That contrast may become one of its strongest selling points. Buyers seeking Saratoga’s privacy, schools and foothill setting do not necessarily want traditional interiors or decades of renovation work. At 20388 Hill Avenue, the proposition is immediate: modern design, completed landscaping, and resort-style amenities presented as a move-in-ready package.
The result is one of Saratoga’s most ambitious current offerings, pairing the scale of a private compound with the polished presentation of a newly completed contemporary estate.
