Step into timeless elegance with this one-of-a-kind historic, almost 5000 sq ft estate, fully renovated in 2022 and thoughtfully modernized while preserving every ounce of its original charm! Perfectly situated on nearly five flat, usable acres, this property combines luxury, character, and resort-style amenities. The outdoor grounds are designed for both relaxation and recreation, featuring a fenced in-ground pool (all equipment replaced in 2019), a pool house complete with an additional full bath and kitchenette, volleyball court, par-3 golf hole, chicken coop, and gardening area. Outside also includes a detached shed with a carport and a two-level storage barn (which could easily be converted into a detached garage as well) with a finished loft and pellet fireplace, offering endless possibilities… ideal for a home office, home schooling, a studio, or a guest suite. Enjoy evenings on the wraparound porch (redone just 1 year ago) or gather around the outdoor brick fireplace for year-round entertaining… you can truly have it all here! Inside, the grand foyer sets the tone with a sweeping staircase and rich heart of pine hardwood flooring that flows throughout. The office off the foyer features tasteful built-ins, while the spacious formal dining room centers around a striking gas fireplace. The living room showcases a historic bar, a free-standing gas fireplace, and doors leading to the outdoor living area. The kitchen is truly the showpiece of the home — a breathtaking chef’s space with Italian Officine Gullo sinks, a 60” Italian double oven with heritage knobs, Sub-Zero paneled refrigerator, drawer dishwasher, dual reverse osmosis faucets, porcelain counters, coffered ceilings, a HUGE island with an additional sink, and tons of cabinetry… all overlooking the sweeping views of the backyard and pool area. An additional stunning family room with a wet bar and access to the wraparound porch, a half bath, and access to a convenient basement storage area complete the main level. Upstairs, the primary suite offers abundant natural light, two walk-in closets, and a spa-inspired bath with dual vanities, a soaking tub, and walk-in shower. Three additional bedrooms share a beautifully updated full bath, while a guest suite with an additional full bath provides perfect accommodations for visitors (5 bedrooms total upstairs). Upstairs also includes a well-designed laundry room and walk-up attic with tons of storage space! Impeccably maintained and unlike anything else on the market... this extraordinary home offers the rare combination of historic character, high-end craftsmanship, and modern livability. Welcome to your next chapter!
