The heart of 4506 Isabella Lane lies under the sky. Enter through the main gate and a full Preston Hollow acre opens up - three structures drawn around a sweeping lawn the way chairs are pulled up to a fire. This is a compound with three front doors, and each was given a job. The Pool House does the entertaining. The Sanctuary - the main residence - is where daily life happens. The Cottage takes whoever else is staying, for a weekend or a year. Every other acre in Preston Hollow asks one building to do all three at once. This one never had to. The Pool House: a full kitchen, bar and lounge opening to covered, heated dining on two sides; below, a screening room with tiered seating and a game room with a pool table, shuffleboard, foosball and a bar. The sound system runs the length of the compound, inside and out. The 75-foot pool runs along one edge, and the heated spa is sized to swim in straight through the Dallas winter. A hundred people, and not one of them walks through your kitchen. The main residence's 4,449 square feet were comprehensively renovated in 2022 - kitchen, baths, hardwoods, windows, appliances and mechanicals. Upstairs is entirely private: a primary suite, three additional bedrooms and a game room. Downstairs keeps its own hours. Across the green, a fire pit, an acre of open lawn and a vintage Airstream, permanently parked - a campground that switches on the moment the sun goes down. The Airstream stays with the house. The Cottage: two thousand square feet with a steam shower, wet bar and air-conditioned basement, taking four shapes - two ensuite bedrooms; a bedroom and a gym; two offices; or a guest suite on one side and an office on the other. For all its seclusion, Inwood Village, Dallas' top private schools, Love Field and the Park Cities are minutes away.
