Designed for conservationist, mountaineer, and real estate developer Duncan McDuffie back in the 1920s, this landmarked property in Berkeley once hosted abundant tony social gatherings and progressive political events.

Now, its current owners have thoroughly restored the McDuffie Estate, surrounded by gardens created by the famed Olmstead Brothers, to its original grandeur and are ready to turn it over to the next generation of caretakers.

The eclectic Spanish-style home sits on a lush acre of grounds that have been revitalized by landscape architect David John Bigham. Its own little eden, the land is fed by an onsite well and a recirculating waterfall.

Expectedly, the elegant mansion is intended for entertaining. A grand living room presides over the first floor with soaring ceilings, exposed beams and ornate details, while a trio of French doors open onto the gardens. Against a backdrop of arched doors, the formal dining room has its own fireplace as well as views to the courtyard and fountain. The kitchen was already extensive with two full islands, plenty of built-in cabinets, and a breakfast area, but has recently been reimagined to accommodate even larger parties with a new back wall that opens to the garden's brick patios. For quiet moments, there is also a study and a sweeping library with a circular fireplace and wet bar.

The second floor feels like a private retreat with a master suite that holds a gracious dressing room and spa-like sanctuary with a soaking tub and steam shower. On the third floor, the "chauffeur's quarters" have been converted into a a bright studio with vast windows, a full bathroom, and plumbing for the option of a small kitchen.

On the lowest level is an ensuite bedroom with a plethora of amenities including a media room, a terrace overlooking the heated swimming pool, a wet bar and wine cellar.

Additional modern creature comforts including solar panels and a Tesla power wall.
