**Headline** View Estate Behind the Gates of The Country, Diamond Bar
Set on over an acre on the slope side of the ridge inside the guard-gated Country Estates, this Mediterranean-style home enjoys views in two directions: city lights out front and green canyons, rolling ridgelines and distant mountain peaks out back. Curved brick steps and a herringbone brick walkway lead past a wall fountain to carved-wood double doors with leaded glass. Beyond a wrought-iron gate, a private walled courtyard holds a free-form pool and raised spa wrapped in palms and tropical plantings.
Inside, vaulted ceilings, a sweeping oak staircase and a crystal chandelier and marble flooring set the tone. Two steps up from the entry, a raised formal living room with plantation shutters glows with filtered light, and an upstairs gallery overlooks the main level. The two-story glass sunroom is the heart of the home, with walls of windows, tile floors, built-in window seating and a pass-through bar.
The primary suite has vaulted ceilings, a private loft and a balcony. Its dressing area has dual sinks, a makeup vanity and Hollywood lighting, and a tiled soaking tub sits beneath a picture window framing the canyon view.
Upstairs, two bedrooms share a Jack and Jill bath, and one has its own private patio. A second patio off the upstairs hall overlooks the pool courtyard and the city lights beyond. A main-floor bedroom suits guests or multigenerational living, with potential for ADU conversion.
Out back, a covered patio overlooks cascading bougainvillea and the canyon. A timber pergola with two porch swings, shaded flagstone seating nooks, and a dry creek bed with a wooden footbridge wind through drought-tolerant gardens.
The real opportunity is the land. The acre-plus downslope lot is ideal for significant expansion, with room to build into the hillside for added living space, a lower-level garage and more. Buyer to verify with the City of Diamond Bar and HOA.
With a three-car garage, the home is ready for the next owner’s vision, with the setting, views and bones that can’t be recreated.
The Country offers 24-hour guard-gated entry, patrol security, a pool, clubhouse, tennis, pickleball, basketball and badminton courts, parks and trails. Minutes to the 57 and 60 freeways. Served by Walnut Valley Unified; buyer to verify school assignment.
