The Country Neighborhood Market Intelligence

The Country, Diamond Bar

Behind impressive gates and mature landscaping, The Country stands as one of Diamond Bar's most prestigious residential enclaves. This exclusive guard-gated community spans rolling hills and canyon terrain, where sprawling custom estates and equestrian properties define a lifestyle of unparalleled privacy and luxury. Located in the eastern reaches of Los Angeles County, The Country offers residents a secluded retreat while maintaining convenient access to the greater metropolitan area's business and cultural centers.

Lifestyle & Amenities

The Country Club serves as the social and recreational centerpiece of the community, providing residents with world-class amenities in an intimate, members-only setting. The club features championship golf facilities, tennis courts, fine dining venues, and elegant event spaces that host everything from casual family gatherings to formal celebrations. The club's equestrian facilities complement the community's horse-friendly design, with many properties featuring private stables, riding arenas, and direct access to miles of scenic trails that wind through the surrounding hills.

Beyond the gates, Diamond Bar offers additional recreational and dining options, including the Diamond Bar Golf Course and various shopping centers along Diamond Bar Boulevard. The nearby cities of Chino Hills and Walnut expand dining and entertainment choices, while the San Gabriel Mountains provide hiking trails and outdoor recreation opportunities just minutes from home.

Real Estate Market

Custom-built estates typically sit on lots ranging from one to several acres, with many properties designed to accommodate equestrian pursuits through private stables, riding rings, and paddocks. The median home value of $839,700 reflects the community's luxury positioning, though many properties sell for significantly higher amounts depending on lot size, custom features, and equestrian facilities.

Architectural styles within The Country vary from Mediterranean and Spanish Colonial to contemporary and transitional designs, with most homes featuring extensive custom details and high-end finishes. Properties often include features such as gourmet kitchens, wine cellars, home theaters, guest houses, and resort-style outdoor living spaces with pools, spas, and entertaining areas. The combination of large lot sizes, custom construction, and exclusive location creates a market where properties retain strong value due to limited inventory and consistent demand from affluent buyers seeking privacy and luxury.

The community's mature landscape and established nature means new construction is limited, with most sales involving existing custom homes. Properties with equestrian amenities typically command the highest prices, particularly those with premium lot positions offering mountain or valley views. The guard-gated security, country club membership opportunities, and maintenance-free lifestyle appeal to successful professionals, business owners, and retirees who value exclusivity and comprehensive amenities.
