About this unit

Exquisite south-facing 1,700-square-foot concrete loft in the heart of River North, offering two oversized bedrooms, soaring open spaces, rich textures, timeless high-end finishes, and bespoke details throughout. The expansive living, dining, and chef's kitchen flow seamlessly together, complemented by top-of-the-line appliances and a custom 8.5-foot honed-granite bar with beverage and wine refrigerators. The spacious primary suite features a walk-in closet, spa-like bath, and ample room for a lounge or work-from-home area, while the second bedroom is currently arranged as a stylish den and office. A large Trex balcony provides space for grilling, seating, and gardening, and the home includes generous customized closets, an oversized laundry and utility room, and a private storage room across the hall. Set on the quiet side of Ontario Street near parks, restaurants, shopping, transit, the Riverwalk, Loop, and Fulton Market, this move-in-ready, pet-friendly home delivers exceptional space, outdoor living, and a distinctive city-chic character.

Where it is

FAQ

Where do these listings come from?

Straight from the Midwest Real Estate Data (MRED) MLS, refreshed regularly — the same listings your buyer's agent sees, no curated subset.

Can I work with Dibze to buy?

Yes. A licensed Chicago buyer's agent lines up tours, writes offers, and handles the close. The seller pays the commission, so it's free to you — and we rebate part of it back at closing.

Can I rent in this building?

If owners are leasing units, the For Rent tab shows them. These are individual condo owners listing through the MLS, so lease terms and pet rules vary by unit.

How is this different from Redfin or Zillow?

Same MLS feed, different model — we don't sell your contact info or turn every click into a lead. One Dibze condo expert handles your whole search and represents you, not the seller.
