Welcome to 3182 Ashbourne Dr, an exceptional 7-bedroom, 6.5-bath executive estate with breathtaking, unobstructed views of the entire Mt. Diablo range. Northwest-facing and nestled within the prestigious gated community of Norris Canyon Estates, this expansive residence offers refined finishes, generous living spaces, and exceptional flexibility for multigenerational living. A polished marble foyer creates an elegant first impression, complemented by plantation shutters, distressed hardwood floors, and beautifully appointed interiors. The main level features a private study, formal living and dining rooms, eat-in kitchen with stainless steel appliances, laundry room, powder room, and spacious family room with gas fireplace opening to a large view deck. An ensuite bedroom provides an ideal private retreat for guests or extended family. The lower level adds even more versatility with a bonus room, quartz kitchen, two bedrooms, and full bath, opening directly to a beautifully landscaped backyard. Thoughtfully designed plantings frame the outdoor living spaces, while a tranquil water feature, fire pit, covered patio, travertine pavers, and synthetic lawn create a peaceful setting for entertaining or relaxing. Beyond the backyard, a terraced hillside offers a rare opportunity to create a private garden, orchard, or vineyard. Upstairs, the spacious primary suite captures spectacular Mt. Diablo views and includes a retreat and luxurious granite bath with two large vanities, walk-in shower, oversized soaking tub, and spacious walk-in closet. Two additional ensuite bedrooms, a large office, and bonus room with picture window complete the upper level. A finished four-car garage adds convenience. With multiple living areas and private bedroom suites, this exceptional property offers a rare combination of luxury, space, and multigenerational living potential.
Norris Canyon Estates, located between San Ramon Valley Boulevard and Crow Canyon Road, is a gated and hillside Norris Canyon neighborhood with winding private drives and canyon-view homes. The streets trace the folds of Norris Canyon, with Mediterranean-inspired facades and large lots set against oak-dotted slopes. The neighborhood’s character concentrates at the Norris Canyon Road gatehouse, where quiet lanes meet trailhead energy and weekend cyclists pass in small clusters. A short drive away, Canyon Lakes Golf Course & Brewery sets a clubhouse-and-patio rhythm for afternoons. Bishop Ranch’s City Center adds a polished mix of dining and retail in a modern plaza setting. Las Trampas Regional Wilderness frames the backdrop with ridgelines and long, open-sky hikes.

Planned Unit District
A large-scale integrated development or a general plan special area of concern provides an opportunity for, and requires cohesive design when flexible regulations are applied; whereas the application of conventional regulation, designed primarily for individual lot development, to a large-scale development or special area may create a monotonous and inappropriate neighborhood. The planned unit district is intended to allow diversification in the relationship of various uses, buildings, structures, lot sizes and open space while insuring substantial compliance with the general plan and the intent of the county code in requiring adequate standards necessary to satisfy the requirements of the public health, safety and general welfare. These standards shall be observed without unduly inhibiting the advantages of large-scale site or special area planning.
