1660 Sylvaner Avenue

Situated on St. Helena's prestigious Westside, 1660 Sylvaner embraces the quintessential Wine Country Lifestyle. Nestled against neighboring vineyards and mature redwoods, the expansive parcel provides a private, serene backdrop for this 2,370 +/- square-foot European-inspired cottage. Custom-built by the current owners in 1984 with updates thru the years, the home reflects an exceptional level of craftsmanship and attention to detail, from its elevated stone terraces and handsome facade to curated artisan-crafted woodwork, open beamed ceilings, and river-rock fireplaces. Expansive French doors and windows bathe the interiors in filtered natural light, while offering a garden view from nearly every room. Gracious entertaining begins at the entry, where a glistening copper bar sets an inviting tone and flows seamlessly outdoors to a series of layered gardens showcasing roses, hydrangeas, ornamental grasses, and fruit trees. Arbor-covered vignettes are framed by mature redwoods, creating intimate spaces for gathering and relaxation, all complemented by tranquil vineyard views.
