A rare find, a spectacular addition (the early 2000s) expanding the original home on a premium 4.46-acre lot in Avon. The 955 sqft addition created a dramatic two-story entry foyer, a Cooks kitchen, the addition of a masonry fireplace in the living room, and a new Solarium. The architect designed an upper-level, primary suite, which incorporates a fully glassed steam shower with radiant heated floors and contemporary cabinetry. An upper balcony overlooks nature and the gardens. In a private alcove, you'll find a sitting room, perhaps your reading library. Custom closets (double) lend just a bit more quietness to the library. One can open any and likely all, of the atrium French doors for the sounds of cascading waterfalls. The interior design merges with exterior water views. Intimate platforms overlook koi ponds, and attach to bridges, all inviting a relaxing space of serenity on your own oasis which captures western sunsets. The hardscape of blue stone walkways, and its gentle elevation of stone walls, invite both dining and lounging patios for full outdoor engagement and offers an on-grade bonus, an outdoor hot tub area within a large fenced area for your pets. From an intimate dinner party to large events, this house is an entertaining gem!
