*** MODERN MASTERPIECE WITH UNRIVALED OCEAN VIEWS *** Perched on a PRIVATE, STREET-TO-STREET LOT at the end of a QUIET CUL-DE-SAC, 900 GAINSBOROUGH DRIVE is a CONTEMPORARY ARCHITECTURAL TRIUMPH offering some of the most BREATHTAKING OCEAN AND CITY LIGHT VIEWS in all of LAGUNA BEACH. Encompassing approximately 4,100 SQUARE FEET across THREE LEVELS, this CUSTOM ESTATE spans TWO ADJACENT PARCELS—presenting a rare opportunity to add a POOL, SPA, OR GARDEN PAVILION overlooking the PACIFIC OCEAN. Reimagined in a COMPREHENSIVE 2015 REMODEL, the residence blends SOPHISTICATION AND MODERN ELEGANCE, featuring SOARING CEILINGS, WALLS OF GLASS, a SPIRAL STAIRCASE, SMART HOME AUTOMATION, ELEVATOR ACCESS, and SEAMLESS INDOOR-OUTDOOR LIVING that captures PANORAMIC COASTAL VISTAS from nearly every room. The MAIN LEVEL is anchored by a SHOWSTOPPING OCEAN-VIEW GREAT ROOM, opening to an EXPANSIVE TERRACE adorned with VINTAGE TILE—an ENTERTAINER’S DREAM. The CHEF’S KITCHEN boasts SLEEK MIELE APPLIANCES, CUSTOM CABINETRY, a LARGE ISLAND WITH SEATING, and a WALK-IN PANTRY. Two EN-SUITE BEDROOMS, a FULL GUEST BATH, and a SPACIOUS LAUNDRY ROOM complete this level. The ENTIRE UPPER FLOOR is dedicated to the OWNER’S RETREAT, a private sanctuary with SWEEPING OCEAN AND CATALINA ISLAND VIEWS. This LUXURY SUITE features a SPA-INSPIRED BATH with DUAL WALK-IN SHOWERS, a FREESTANDING TUB WITH FIREPLACE, PRIVATE SITTING AREA, and a VIEW BALCONY perfect for SUNSET UNWINDING. The LOWER LEVEL offers REMARKABLE FLEXIBILITY, with a SEPARATE LIVING AREA, FIREPLACE, KITCHENETTE, and PRIVATE PATIO—ideal for a GUEST SUITE, HOME OFFICE, GYM, STUDIO, or MEDIA ROOM. Outside, MULTIPLE TERRACES AND GARDENS embrace the essence of SOUTHERN CALIFORNIA LIVING. Two SEPARATE 2-CAR GARAGES and EXTENSIVE STORAGE enhance functionality, while its construction on SOLID BEDROCK ensures EXCEPTIONAL STRUCTURAL STABILITY. Just minutes from WORLD-CLASS BEACHES, SCENIC HIKING TRAILS, UPSCALE DINING, and the CULTURAL CHARM OF LAGUNA VILLAGE, 900 GAINSBOROUGH DRIVE is more than a home—IT’S A LEGACY ESTATE THAT DEFINES COASTAL LUXURY LIVING.

As a licensed real estate brokerage, Estately has access to the same database professional Realtors use: the Multiple Listing Service (or MLS). That means we can display all the properties listed by other member brokerages of the local Association of Realtors—unless the seller has requested that the listing not be published or marketed online.
The MLS is widely considered to be the most authoritative, up-to-date, accurate, and complete source of real estate for-sale in the USA.
Estately updates this data as quickly as possible and shares as much information with our users as allowed by local rules. Estately can also email you updates when new homes come on the market that match your search, change price, or go under contract.
