You've driven past it—this brick-clad consulate-turned-mansion—a hundred times, and wondered, who lives there? Could it soon be you?

You would walk up the marble stairs to the iron-and-glass front door and quickly realize that, despite its historical, somewhat humble-for-its-size exterior, your Pac Heights home is a modern mansion in disguise. Open the doors and you'll be greeted with a sleek, spacious interior—five floors of French paneling, high ceilings, custom fireplaces, and more.

The main floor is perfect for entertaining: It has a reception room, a formal living room (sunny viewing terrace, anyone?), a formal dining room, and a service kitchen. The kitchen is only one of three in the entire house, and is totally a chef's geek-out paradise—besides stainless steel countertops and sparkling white tile walls, it has a Miele professional dishwasher, a Sub-Zero fridge, and a Viking four-burner cooktop with a Wolf custom hood.

For the previous family, the living quarters didn't even start until the third and fourth floors—but now, the master suite is lavishly spaced out over the second floor, along with three additional bedrooms and two office spaces. The master suite has floor-to-ceiling windows, dark wood vanities in the bathroom, and—the real gem—a Narnia-like walk-in closet that never seems to end.

The third and fourth levels are really for the family—if you think cozy and luxe go in the same sentence. They hold a beautiful foyer, another fully equipped kitchen, a great room with a terrace (and sweeping views of the city), and five more bedrooms.

And no, we didn't forget that fifth floor: The basement holds an industrial kitchen—for hosting gatherings or galas of any size—a wine cellar, and five additional rooms to be whatever you can imagine. Oh, and bringing up the rear, is a private, Downton Abbey–style "servants' staircase" connecting all four floors from the back of the house.

We told you it was a mansion. Now go play Lady Mary.
