About This Home

As of June 2026

Main House: 4 Bed | 2.5 Bath | 3,271± Sq. Ft. | .55± Acre Lot Guest House: 1 Bed | 1 Bath | 730± Sq. Ft. 1,500-Bottle Wine Cellar | Subterranean Car Lift | 788± Sq. Ft. Garage Tucked into a treasured setting in Happy Valley, 1089 Rahara Drive offers a rare sense of calm that’s felt the moment you arrive. Set above the rhythm of everyday life, the home carries that feeling throughout, with natural light, generous volume, and a floor plan that feels both intuitive and welcoming. This is a home designed to be lived in with ease, where thoughtful details and warm, livable spaces come together in a way that feels effortless and lasting. THE MAIN HOUSE At 3,271± square feet, the main house lives larger than expected. Tall ceilings lift every room, light pours in from multiple directions, and the floor plan has an easy logic to it, the kind that makes daily life feel effortless rather than managed. There are nooks that become favorite spots: a kitchen bay window, a mudroom off the kitchen that quietly absorbs the chaos of coming and going, a bar with its own counter and sink that earns its place every single evening. The kitchen is the heart of it. Two skylights overhead and windows that frame the outside make it one of the brightest, most welcoming rooms in the house. Calacatta Bettogli marble runs across the counters, and the appliances, Wolf, Sub-Zero, Miele, are the kind that disappear into the background and simply perform. The walk-in pantry keeps everything in its place. The primary suite is quiet and considered: limestone hexagon floors, a custom walnut vanity, brass fixtures, a large shower with a built-in seat, and a walk-in closet that is genuinely outfitted rather than merely large. Down the hall, paneled ceilings and wainscoting give the home a sense of architecture in the spaces between rooms, the kind of detail that you notice and then can never un-notice. THE GUEST HOUSE The 730± square foot guest house has its own gravitational pull. A private balcony off the bedroom, a marble and limestone bath, a living space with a built-in lounge. Guests settle in and stop counting the days. Ideal for extended stays or a home office, it’s a space that adapts easily depending on what’s needed. THE WINE CELLAR A temperature-controlled, 1,500-bottle wine cellar designed for proper storage. For collectors, it’s essential. For others, it’s a standout feature that adds depth and character to the home.
