Welcome to 128 Langdon Drive, where nearly 6,000 square feet of exceptional living space meets an outdoor setting worthy of a private resort. Set on a landscaped .81-acre cul-de-sac lot, this 5-bedroom, 5.5-bath home backs to mature trees with no neighbors directly behind it. A three-car garage, friends' entrance and massive French doors create an impressive arrival. Meticulously prepared for its next owner, the home features freshly refinished hardwood floors throughout the main level and stair treads. The foyer opens to a banquet-size formal dining room and guest suite with hardwood floors, walk-in closet and en suite bath. A dedicated office features extensive built-ins. An exposed brick archway leads to the formal living room, where a custom mantel, gas-log fireplace, built-ins and extraordinary sliding glass doors showcase the backyard. The private primary suite offers hardwood floors and a sitting area overlooking the wooded backyard. Its bath provides separate his-and-her sides, each with a quartz vanity and large walk-in closet, plus an oversized jetted tub and walk-through shower with multiple showerheads. A custom powder room features a furniture-style quartz vanity and beautiful sconces. The kitchen, keeping room and breakfast area form the heart of the home. The exceptional kitchen includes a large granite island with bar seating, custom backsplash, contrasting cabinetry and quartz-topped buffet with glass-front display cabinets. The Thermador package features a built-in Wi-Fi-enabled refrigerator, gas cooktop with griddle, microwave and double convection ovens. A wet bar offers a wine cooler, ice maker, sink, granite counters and glass-front cabinetry, while a huge walk-in pantry provides outstanding storage. The keeping room is anchored by a floor-to-ceiling exposed brick fireplace. The friends' entrance opens to a drop zone with a built-in desk and wall of cabinetry. The multipurpose laundry room includes ceiling-height cabinetry, quartz counters, utility sink and hanging space. Even the epoxy-finished garage stands apart with two oversized storage rooms, including a workshop with cabinetry, deep sink, pegboard and space for two refrigerators and wiring for an EV charging station. Upstairs are three bedrooms, three full baths, a built-in reading or study area and oversized bonus room. Two bedrooms have private baths, while the third shares bath access with the bonus room. A remarkable secondary living suite can serve as guest or in-law quarters, media room or entertaining space. It includes living and dining areas, an oversized custom island, sink, ice maker, beverage refrigerator, custom cabinetry, wine storage and smoky mirrored backsplash--perfect for movie nights, card games or mah-jongg. An additional storage section includes shelving, a holiday closet and attic access. The outdoor living is the defining feature of 128 Langdon. The enormous screened porch functions as a true outdoor room with tongue-and-groove ceilings, concrete flooring, ceiling fans, granite serving bar with stainless storage, dining and living areas, and a dramatic floor-to-ceiling brick fireplace with TV connection. Beyond the porch, covered and uncovered patios surround an exceptional outdoor kitchen. A substantial granite island with bar seating complements the built-in grill, hibachi grill, refrigerator, large sink and space for a Big Green Egg. The gunite pool and spa are surrounded by beautiful stonework, generous decking and areas for lounging, dining and gathering around the fire pit. The iron-fenced backyard extends beyond the pool with room for play equipment, pets or lawn games, all against a private backdrop of mature trees. With approximately 5,978 square feet, an office, bonus room, secondary living suite and extraordinary storage, this extensively enhanced home is truly move-in ready. Enjoy it all in Reunion, one of Madison's premier communities, with lakes, neighborhood amenities and optional club membership.
