About This Home
As of May 2025Welcome to 27 Halsey, a sophisticated sanctuary in the heart of West Petaluma. Nestled atop ⅔ of an acre, this exquisite property has been meticulously designed for the ultimate indoor-outdoor living experience. Stepping inside, cascading natural light pours in from every angle, illuminating the cathedral tongue and groove wood-lined ceilings. Designed with an open-concept layout, the home offers a seamless flow between spaces, accentuating its endless upgrades and refined finishes. Step outside the kitchen onto the expansive wraparound TimberTech deck, where the resort-style backyard unfolds before you. At its heart, an oversized PebbleTec-lined saltwater pool, complete with a Baja step, elegant water features, and an integrated hot tub. Beyond the pool, the outdoor amenities continue with a basketball court, bocce ball court, spacious stamped concrete areas, exterior lighting, mature trees, and an expansive lawn. Tucked behind the 3 car garage, a charming 1-bed, 1-bath guest house offers privacy and comfort. Encircled by mature hedges and secured by a private gated entry, this home offers a serene retreat while being just minutes from historic downtown Petaluma. A rare blend of luxury, privacy, expansive views, and prime location-27 Halsey is truly a world of its own.
