The ultra-exclusive Conrad Alfred Meussdorffer–designed, Beaux-Arts–style building at 2006 Washington Street is widely held as one of San Francisco's most luxurious residences, with intricate architectural details, sweeping terraces, and elegant gardens.

Characteristic of the architect's grandiose flair, the building opens with a dramatic porte-cochére and a spacious foyer marked by Versailles-patterned hardwood floors.

Several of the 1924 building's 10 full-floor apartments have been published, from here at 7x7 to the pages of Architectural Digest. Now, a stunning two-level, four-bedroom duplex has hit the market and it's giving us all the lush Mediterranean vibes.

Apartment #2 spans nearly 8,000 square feet with rooms as gracious and pretty as you'd expect for $30 million. The living room has ornate details including a carved fireplace, intricate millwork, and Greek-style columns and is illuminated by several large windows that look out to the Golden Gate Bridge, Alcatraz, and Russian Hill. An adjacent library and sitting room have access to a large terrace that opens onto the cooperative's private gardens.

Meals in the formal dining room will compete with bay views from a north-facing terrace; there is a separate butler pantry for storing away the silver. The chef's kitchen is surprisingly homely for such a lavish manor, with a charming blue-and-white tiled backsplash, marble countertops, and a breakfast area. Cooks will appreciate double ovens, and oversized cooktop, and tons of counter space. The kitchen is semi-open to an office, family room, laundry room, and one of four half-bathrooms.

On the southern end of this floor is an en suite bedroom with views of Alcatraz and Lafayette Park. There is also a conservatory that opens to a terrace and another powder room.

The upper level is dominated by the primary suite with dual en suite bathrooms as well as two private dressing wings with marble-clad bathrooms and spacious closets.

A winding wrought iron staircase transitions to the lower level with a grand ballroom or family room with high ceilings and oversize Palladian windows opening up to a circular terrace. With its own gated entrance from Washington Street, this level makes for ideal guest quarters with two en suite bedrooms, a fitness room, service area, laundry room, storage rooms, and another half-bathroom.

With opulent but not too-over-the-top design and a myriad of spaces to enjoy indoor-outdoor living, it's no wonder this building is one of the city's most sought-after residences for homebuyers with cash to spare.
