This modern mansion on Mercer Island is spectacular with its own beach, but the star of the show is the coolest pool around.

“The infinity edge, you just look straight out to the lake,” said Moya Skillman of Avenue Properties. “It's so serene and pretty. If you get down like water level, you can see why it's an infinity pool. You can see all the way.”

The house is on the North end of Mercer Isle and describes as an “iconic, modern, waterfront retreat.”

The grand entrance to the home is a set of solid copper doors on pivot-style hinges that were crafted on site.

The entire estate, built in 2002, has a gallery feel since the current owners are very into art.

“They have an amazing art collection. So, a lotta the elements in the home are exactly that. They're art pieces on their own,” said Skillman.

Step into the master bedroom and you’ll get a feel for this through the grand windows with sweeping views.

You wake up to your aforementioned pool and Lake Washington beyond. The master bath will light up your life too.

“It's a very kind of light and airy stone and it allows the light to come thru,” said Skillman. “So, it's very light and bright even though it's private and intimate.”

There’s even your own personal towel warmer.

With modern architecture, things can come off as being a little too edgy or cold. But this mansion has a little warmth to it.

Features like the floating steel staircase showcase the glass and metal throughout, but wood accents counter the cool tones.

And the 5,000 plus bottle cellar is one of the largest you'll ever see.

The wine cellar holds more than 5,000 bottles of wine.

Another rarity so close to the city, the private beach that highlights the 124 feet of waterfront.

“Their kids loved to have all their friends over in the summer,” said Skillman. “So that whole waterfront experience with the pool and being able to go to the lake really made it special.”

Sleek, calm, cool and collected on your own slice of Mercer Island.

The house is currently listed with Foster Realty at $15 million.
