Live surrounded by nature within a comfortably elegant & serene sanctuary made for entertaining in Alhambra Valley- minutes to cafes and shops with hiking biking and horseback riding nearby. Or simply relax in the heated pool or spa or among several outdoor spaces set over 6+ acres; Redwoods, poolside pergola, firepit area, vine-covered shaded patio, vegetable garden or possible pasture Make your grand entrance as you pass the pool into an open and inviting great room where a stone fireplace anchors gracious living and dining in seamless harmony, or via a large designer chef's kitchen with upscale appliances and several work spaces. Upstairs natural light and calming views are yours' through large newer windows in multiple bedrooms with two well-appointed full baths- one with clawfoot tub plus a separate room for laundry and crafts These rooms are very flexible so it's an ideal opportunity to get creative as your desired use of each changes. Behind the house and up a short hill you'll discover another golden opportunity: a semi-converted barn with workshop, large loft space and rustic wine cellar. Will this become your guest house/ short term rental or creative/ meditative retreat? Or convert it back to a working barn? The choice is yours'!
