Here is something you don't find every day: an estate-quality Northgate residence that pairs the soul of a 1940s original with the grand scale of a meticulous mid-1980s addition. The result is approximately 4,600 square feet of living space - and it feels almost like two homes in one, offering rare flexibility for multi-generational living, guests, or a private home-office wing. An opportunity to make it your own: with some updating and a maintenance catch-up, this estate becomes exactly what you envision Two Primary Suites - Truly!!! Upstairs, the Primary Retreat features soaring wood-beamed ceilings, a cozy sitting area, a fireplace, and a private deck -with Mount Diablo views as your backdrop. His-and-hers walk-in closets, a beautifully tiled walk-in shower, and a tub with pool views make it a true sanctuary. Downstairs, a second Primary Suite with its own full bath offers main-level convenience - ideal for guests, or whatever your lifestyle calls for Grand Spaces for Everyday Living The addition's heart is a vaulted Great Room with soaring ceilings and abundant natural light, anchored by a full wet bar and crowned by a stunning stained-glass piece, with a side patio. A formal Dining Room boasts beamed ceilings, while the Leisure Room centers on a wood-burning stove. A spacious Breakfast Room next to the generously sized Kitchen, a Wine Closet, a Pantry, and a Laundry/Pantry Foyer with Half Bath complete the main level. A circular staircase, redwood woodwork, wainscoting, and three fireplaces throughout lend an old-world European character that simply cannot be replicated Outdoor Living set on a nearly three-quarter-acre lot, this is an entertainer's-and-gardener's paradise: a swimming pool with a shaded pool house, mature fruit trees, a workshop, and chicken coop. A gated concrete pad offers rare RV/boat parking - or room to dream bigger. A three-car garage and a second driveway add everyday ease Northgate: one of Walnut Creek's most sought-after neighborhoods, moments from Arbolado Park, Valley Vista Golf Course, and the Contra Costa Canal Trail, with The Orchards at Walnut Creek, downtown shops and dining, Walnut Creek BART, and I-680 all within easy reach.
