This home has hosted a full life, and the guest list keeps coming back. Not occasionally, but for countless meals, everyday celebrations, long weekends, and visitors in town. The great room is where that life gathers. Ceilings lift to a vault and a full wall of windows turns the yard into the view from nearly every seat, making it the room the rest of the house defers to and the one that sets the pace for the evening. What makes the hosting sustainable is the privacy built in behind it. The main entry foyer opens to a formal dining room, a separate living room, and a private office, so the working day and the dinner party never have to share a footprint. Off the kitchen, a morning room looks out over the pool, which is where most days here start. A generous pantry sits off the laundry room, the kind of detail that only reveals its value when the house is full. The primary suite holds two closets, one custom-fitted as a walk-in. Hardwood and ceramic tile run throughout, with carpet in a single guest room. The deck is the main stage. It spans wide enough for a band, a dance floor, and a sit-down dinner at once, and a built-in prep station with its own sink means the host never has to disappear inside to keep things moving. Below it, the pool reads as a continuation of the deck rather than a separate destination, stepping down into the yard, and a lower terraced section opens further still for games and recreation. The house handles a weekend guest and a long-term one equally well. Rooms stay private, spaces stay connected, and there is no need to choose between them on a given evening. The unfinished lower level carries infrastructure already in place for whatever comes next, serving in the meantime as storage and hobby space. Some homes are designed for entertaining. This one has the history to prove it. This special residence stands as a rare combination of scale, flow, and genuine outdoor living. See it for yourself when doors open to the house on Saturday 10/10 from 1-4pm.
