Live and work luxuriously in this top-floor Tom Kundig penthouse

The Tom Kundig-designed Art Stable Building, named for the stable formerly on the site, has just five units. All of these condos are vast and customizable, but the top-floor unit, currently listed for $6 million, is a live-work masterpiece.

This two-story penthouse is larger than its setting, with 3,919 square feet of space, built out by the original owners with an interior designed by Rhoady Lee, filled with features usually presented as shared amenities.

A west-facing terrace has views of the city and Lake Union, but it’s the terrace’s general massiveness—1,600 square feet, twice the size of many apartments—that make it something special.

Toward the home, the terrace is covered by a glass awning to bring in the sun while still protecting on rainy days, transitioning into a trellis to add greenery to the space. Large planter boxes surrounding the space give it the feel of an oasis in the middle of a cityscape.

Inside, the two stories include a wine cellar, a game room, and a sauna.

Two offices enjoy the same window-lined luxury as the rest of the unit, plus a cozy library.

The space is so occupied with being a little bit of everything that despite its general hugeness, it fits only two bedrooms—plus semi-private nook with a guest Murphy bed. (Don’t feel bad for the guest who sleeps here. It’s under the stairs overlooking those gargantuan windows.)

The floors are connected by a wall of floor-to-ceiling windows facing west, spanning the length of the open staircase.

With an entire compound inside the penthouse, you wouldn’t have to leave much—although it’s placed for leaving pretty often, located at the east end of South Lake Union near REI with easy access to Capitol Hill.

The listing price for this massive piece of South Lake Union is $5.95 million.
