Ask most buyers what a top floor is worth in a Gold Coast tower and they will hand you a formula tied to altitude: higher floor, better view, higher price. At 10 E. Delaware, that formula breaks down the moment the elevator doors open. The 35-story Lucien Lagrange tower at Delaware and State sits close enough to the Four Seasons Hotel, the Waldorf Astoria, and the 900 North Michigan retail block that sightlines from many floors are shaped more by which direction a unit faces than by how high up it sits.
That distinction changes how a buyer or seller should actually price a unit in this building, and the building's own 2026 transaction record proves it.
The Floor Rule That Doesn't Hold Here
Building profiles of 10 E. Delaware are direct about the constraint: views are limited because the tower is boxed in by taller neighbors. That's a different situation from a freestanding high-rise, where a 30th floor reliably outsees a 15th floor in every direction. At 10 E. Delaware, a north or west facing unit on a mid floor can have a cleaner sightline than a south facing unit ten floors higher, because of what's directly across the street.
Unit 14A is a small but useful case. As of June 12, 2026, the one-bedroom plus den, 1,023 square feet with open views to the north and west, was listed at $695,000 and had been on the market for 45 days, handled through Jameson Sotheby's International Realty. Forty-five days isn't a slow sell in a boutique 121-unit building where turnover happens in small batches. It's a sign that exposure, not floor count, was carrying the value.
A second unit, an 845-square-foot one-bedroom, hit the market in March 2026 with an open house scheduled the same week it listed. Position relative to the street and to neighboring buildings, not the number on the door, is what a buyer is actually paying for in either case.
What the Penthouse Actually Buys
Where floor number does matter at 10 E. Delaware is on floors 33 and 34, the only two levels in the entire tower with 10-foot ceilings. Every other floor tops out at nine feet. That's a specific architectural line, not a general sense that higher means nicer.
Unit 34A sold on July 28, 2026 for $3,399,500 at 3,100 square feet, or $1,096 per square foot. That price sits well above the building's typical range, and it tracks the ceiling height more closely than it tracks the floor count on its own. Whoever bought that unit wasn't purchasing altitude in the abstract. They were purchasing one of two floor plates in the entire building with an extra foot of ceiling height, plus whatever exposure that particular stack happened to carry.
At 10 E. Delaware, "high floor" and "good view" are two separate negotiating points. Price them separately, and don't let one stand in for the other.
The Assessment That Changes the Comparison
Two units at 10 E. Delaware can list at nearly identical prices per square foot and still cost very different amounts to carry each month, because parking here is deeded and individually taxed. Each parking space has its own monthly assessment and its own property tax bill, separate from the residence itself. A second space, when one is available, has been priced as high as $50,000 in recent listings.
That means a straight price-per-square-foot comparison between a unit with one parking space and a unit with two isn't really comparing the same product. The monthly assessment complicates the math further in the other direction. Heat, air conditioning, water, and gas are bundled into the assessment rather than billed as separate utilities, so an assessment that looks high against a building where those costs show up as separate bills isn't actually high once it's unbundled.
Before comparing two units at 10 E. Delaware side by side, it's worth checking:
- Which direction the unit faces, and what's directly across from it
- Whether the floor is 33 or 34, the only levels with 10-foot ceilings
- How many deeded parking spaces come with the unit, and whether a second is available
- What's bundled into the monthly assessment versus billed separately
Borrowed Hotel Service, Not Hotel Pricing
10 E. Delaware isn't a hotel-branded building, but it doesn't behave like a plain condo tower either. Room service is available through the neighboring Talbot Hotel, alongside on-site concierge, porter, and housekeeping. Buyers comparing this building to the Four Seasons Residences or the Waldorf Astoria Residences next door are often pricing in a hotel-branded premium that 10 E. Delaware doesn't actually charge, while still picking up a version of the same service.
The block does the rest of the work. Le Bar Chicago, Bernard's Bar, and The Drawing Room sit within feet of the entrance. Potash Bros. Market and Goddess and Grocer cover daily groceries a short walk away, and dinner options within a few hundred feet include Le Colonial, Hugo's Frog Bar & Fish House, and Balsan inside the Waldorf Astoria, with Maple & Ash, Gibson's, Tavern on Rush, and Adalina a few blocks further. Oak Street Beach and Washington Square Park are both within easy walking distance. None of that shows up in a price-per-square-foot spreadsheet, but it's part of why exposure and floor plate, not hotel branding, are what actually separate one unit's price from another's in this specific building.
What This Means If You're Buying or Selling Here
The building's own 2026 activity tells a consistent story. The highest confirmed sale of the year went to a penthouse-level unit with the rare 10-foot ceiling, not simply the highest number on the elevator panel. A one-bedroom with favorable exposure moved through a normal 45-day window despite sitting well below the top of the tower. Neither result makes sense under a pricing model built purely on floor count.
If you're listing a unit at 10 E. Delaware, lead with exposure and floor plate specifics before the floor number itself. If you're buying, ask what's actually across the street from a unit's windows before assuming the higher number on the door means a better sightline. And run the math on deeded parking and bundled utilities before trusting a straight price-per-square-foot comparison between two listings that look identical on paper.
Frequently Asked Questions
Does a lower floor ever sell for more than a higher one at 10 E. Delaware? Yes, when exposure favors it. A north or west facing mid-floor unit can outsell a higher floor unit whose view is blocked by a neighboring building.
What's included in the monthly assessment? Heat, air conditioning, water, and gas are bundled into the assessment rather than billed as separate utilities.
How is parking handled in this building? Parking spaces are deeded and individually taxed, each with its own monthly assessment separate from the residence.
Buying or selling at 10 E. Delaware means pricing exposure and floor plate specifics correctly before the number on the door does the talking.
