Hannigan and husband Alexis Denisof—who co-starred together on television cult-favorite “Buffy the Vampire Slayer”—also own a much smaller spread in Santa Monica.
The gated mini-mansion boasts a 5,864 square foot main house with three bedrooms and four bathrooms in addition to a detached guesthouse with one bedroom, two bathrooms, and its own kitchen.
The main space features a curved staircase in the foyer, a living room with a stone fireplace, and a formal dining room with built-in bay window seating.
The kitchen includes concrete countertops, a spacious center work island, and rows of white cabinetry with glass front doors!
The master suite offers a sitting area—near the room’s fireplace—a private balcony, and a bathroom with a double sink vanity and soaking tub.
The backyard has a huge swimming pool, spa, fire pit, and a large lounge terrace for entertaining guests outdoors.
