Walk through the former three-flat whose interior rarely betrays its actual vintage.

The crisp and reserved brick and limestone structure from the 1920s hides a 4,000-square-foot single-family home that is totally 21st century.

The Property: On the outside it’s a crisp and reserved brick and limestone structure from the 1920s. But inside, this former three-flat, now a 5,500-square-foot single-family home, is totally 21st century. That modern aesthetic begins in the foyer with the lighted acrylic partial wall in the foyer, continues on to the sleek wood, glass, and metal kitchen, and moves up to the soft cork floors in the master bedroom. One particularly artful touch is a screen wall beside the main stairs: its reedy, angled lines suggest bamboo, but it’s actually made of electrical conduit.

Steve Olsher, a developer whose company is called Bold Development, and his wife, Lena Bravo-Olsher, bought the building in 2005 when it was still a three-flat. With the help of the architect Ferdinand Dimalig of Fuel Design Collaborative/Box Studios, they combined the units into one seven-bedroom home and opened the place up, creating two large atriums—one above the kitchen and another above the living room—that bring natural light into spaces that typically would be pretty dim.

As the video tour reveals, the home’s interior rarely betrays its actual vintage. There is a debonair stone fireplace wall in the living room; bamboo flooring in the rooms on the main floor; a sumptuous tile-and-wood entertainment center in the master bedroom; a master bath with blue-glass tiles; and stylish light fixtures throughout.

Complete with an elevator, a basement party room, and a large rooftop deck, the house is crying out to host some swanky parties. And that, says one of the Olshers’ listing agents, is the intention: “I’m thinking we’re going to interest somebody who’s in sports or music, maybe an art gallery person,” says Steve McEwen, who may be able to work some connections from his decade as Steve Fisher on the Chicago radio stations Q101, the Mix, and the Zone.

Price Points: According to Midwest Real Estate Data, Lake View has had 14 single-family-home sales for $2 million or more in the last three years. Of those, 11 have been new construction (12, if you count the fact that one of the houses was sold twice in that short time). None of the homes, old or new, was anywhere near as close to Belmont Harbor as this one, which is just a block and half from Lake Michigan.
