The Chicago Window is a particular design that met the delicate balance of providing light and air into the depths of large towers. For a brief period of time, the need for and the ability to produce these large window was possible with available technology. But today, these windows appear for reasons other than functional necessarity. In this video, we chat with Gunny Harboe who has preserved dozens of Chicago windows in the Reliance Building, Marquette Building, among others. We explore the window's history, why it was such an ideal solution, and what went it the popularity of this ubiquitous architectural element.

Once again I am amazed at Stewart's (and, today, Gunny's) ability to make a topic as mundane as one specific type of window actually compelling and engaging. Bravo.

[@graavy]

RIGHT? Like the titles of some of these videos are ANTI-clickbait

[@davidakariverman-astorytel644]

Agreed.

[@samiam619]

But 12 minutes worth?

[@imlistening1137]

True!

[@lisakilmer2667]

I first learned the term "Chicago window" when we moved to Indiana after living in the Southeast, with its heavy devotion to classical and colonial architecture. I thought the Chicago window was a brilliant idea - to have a picture window with operable side sashes. The aesthetic of a clean expanse of glass is very pleasing, especially in the ubiquitous Mid-century ranch home, or the older bungalows. In a skyscraper, that same rhythm of perpendicular lines created by the Chicago window really does affect the personality of the building, and I never realized it until today.

[@HillaryMoore]

I was about to add a similar comment. Our brick ranch in southwest Indiana has this same type of window. I grew up in Illinois and have family in the Chicago area - I never knew this type of window had a name, or that it was special. It's been everywhere I have lived - except the years we lived in Mississippi.

[@revsharkie]

The 1953 ranch I lived in growing up had that window configuration in the living room. That was in a small town in southeast Kansas.

[@danvondrasek]

My old Chicago house was built in the 1890s as stockyard worker housing. Our house had a giant picture window with 2 smaller opening windows on the side. As did every other house built before the 1950s in the area.

[@jannetteberends8730]

From The Netherlands, I never saw that type of windows. They give a beautiful rhythm to the building. And when they were used everywhere it also gave the city rhythm, I suppose.

[@roberthoople]

Chicago was never a destination on my bucket list, but thanks to Stewart revealing all this amazing architecture and engineering, it's on that list now.

[@Marcel_Audubon]

[@Epitome_93]

Could you do a video on Ice falling off buildings? 🏢 Are there any architectural elements that prevent, mitigate, or solve this problem? Love your channel ♥️

[@kionnakelly2918]

That’s a good idea

[@johncoryell]

yes, excellent idea

[@Pystro]

One element that I know from central Europe is a tiny "fence" (or vertical grate) about 4 inches tall and a few inches from the roof's bottom edge. By holding the snow on the roof It keeps it from avalanching off as a whole. Which it might do due to warm shingles melting the lowest layer of snow, or just too much snow collecting on the roof for friction to hold it. But I bet you can also somehow influence it by modulating the roof slope or by strategically placing gables. Would be a nice topic.

[@rosezingleman5007]

You see a lot of spiked roofs in cold climates. The spikes keep the ice from coming down in large dangerous sheets. Pretty common in vernacular architecture.

[@Epitome_93]

I love the responses. My brain was thinking about skyscrapers, but a video on sloped roofing could be interesting also! There might be a few directions to take the topic.

[@joemeyer6876]

Oh, this is as good as the story of bricks! Stewart, you need to do a story on architectural salvage. Chicago has several businesses that do that; I remember one that had speakeasy bars from the 1920s. . . and of course how they are integrated into current buildings.

[@jamesslate1026]

This is a bit of Chicago's architectural history that I wasn't aware of. So thank you for this insightful video. I'm sure I've walked past the Marquette Building a million times but never ventured inside. I wasn't aware of its Tiffany designed lobby. During the discussion of Chicago windows, I immediately thought of the Monadnock Building, which is one of the few remaining examples of load-bearing walls. It's windows are set up in bays, with three panels side-by-side.

[@charlienyc1]

Next time you're there, walk on through from Dearborn all the way through Revival Food Hall to Clark (or the reverse).

[@HotCoco_]

He tried his best but he got most of this information wrong. The window did not transform Chicago; the Chicago window is named such because of where it was first designed. You actually find these windows far more often in cities outside Chicago than you do here in the Windy City itself.

[@longiusaescius2537]

@HotCoco_ nice pfp

[@henq]

Love the vid, the details make the whole. I was amazed to hear single-pane glass was used at the restoraion mentioned. Here in the Netherlands we have 'resoration glass' that's made out of 2 very, very thin layers of glass, not gas filled, but vacuum. The outward pane can be 'bubbly' on purpose to mimic the not-perfect glass of the old times. Double pane, vacuum isolation, as thin as 6mm (1/4 inch) !

[@Trixtah]

Yes, Pilkington manufactures a product along those lines, which is available pretty much worldwide. I believe it's a relatively recent product, though, and may not have been available at the time they did the building upgrades.

[@nicolegregory4429]

I would never have thought a video about windows of Chicago would make me tear up and feel home sick… but here we are. Chicago is absolutely my favorite place to live. Thank you for this amazing education. Oh! And the art piece behind you is amazing! ~N

[@I.____.....__...__]

I was at a friend's apartment during the holidays and was baffled by the choice of the architects' design for the windows. Instead of vertical sashes on the sides of the static windows, they were horizontal below the static window, near the floor and were fairly large squares. They were the perfect size and position for children or pets or even adults sitting on the low-rise siding in front of them to lean back and fall out. There weren't even screens on them or balconies or anything outside. 🤨 🤦

[@garyd.7372]

People, and stuff, fall out of high-rise windows all too often. Eric Clapton famously lost his 4-year-old son that way, memorialized in his song "Tears in Heaven". A really unlucky tourist, walking on a NYC sidewalk, was struck and killed by a dumbbell that fell out of an apartment window in 1962, which also made headlines as the apartment was occupied by Arlene Francis, then a famous TV personality.

[@Dongonzales123]

I really appreciate your videos a lot. I study city planning in Germany, and of course Chicago comes up quite frequently because of its pioneering role in many aspects of architecture and city planning. I would love to visit it some day, but of course that's way out of my budget as a student. Your videos really make the city come alive and connect the surface knowledge from my lectures with real deep insight into seemingly mundane topics on this fascinating city

[@eugeneo1589]

I find tilt and turn windows (the ones we mostly use in Europe) much, much more practical. This stupid idea of making a tiny (sometimes it's 30x30 cm that's opening and that's it!) windows which only open, and the rest is a fixed window a really stupid and unpractical. Also, they're much more energy efficient - when I first came to North America I was shocked how bad insulation is.

[@AaronSmith-kr5yf]

A lot of suburban mid century ranch houses have the "chicago" style window in the middle of the front facade/in the living room. Love those ranch houses with that feature cause it usually means a wall of glass with a ton of light/awesome view in that front room.

[@kathyastrom1315]

My childhood home near Joliet fits this perfectly. Built in 1969, the 1500 square foot ranch had a brick facade on the front that faced onto the west side of the house. We always had the side windows open throughout the summer when the AC wasn’t on.

[@jenniferh1416]

It's nice for light but impractical for safety with certain styles. A 1950s house was set ablaze by an arsonist. The firemen were surprised and relieved that the family was able to escape through the windows. All of the windows which open were crank style instead of sash openings. I couldn't open one of these as a child because it took a good bit of strength if the window was in working order. Those frames have been steel in a humid climate which does rust. If the window hasn't been opened after repainting, it won't open easily. The windows tended to stay closed due to high humidity and the use of AC.

[@bebeaggad3302]

There is a beautiful poetic sound to the way most architects speak which i love

[@ddawn23]

So giddy to see Pierce Tower featured at 10:47! It was a University of Chicago dorm, home to Henderson, Thompson, Tufts, and Shorey Houses. Built in the 60s and demolished a few years ago. The rooms were quite small and surrounded two-story loft lounges. The rumor among residents when I lived there in the early-mid 2000s was that the intention was that the students would be like monks toiling away in their cells and that the large lounges would encourage house unity and community. For Henderson House when I was there, it certainly did.

[@zachjarrett8730]

Gunny is a treasure. I was the sound designer for the doc on the Emil Bach house. He was the lead on the restoration and a great personality to give the film charm. Class act and great educator.

[@wacojones8062]

I worked as Messenger in the Chicago area for 15 years. I got to see most of the historic buildings inside hauling heavy loads on a1930's hand cart. There are a lot of hidden structural gems to be found. I got to ride in some of the last manned passenger elevators.

[@brunodesrosiers266]

The two-story house I grew up in in Montreal (QC) was built in 1959 and had Chicago window - but only over its main facade. Their proportions were quite similar to those you see in this video, however much smaller. All that was far from rare in our (East-end) part of the city.

[@timmo971]

And thus, Stewart Hicks and his brilliant guests effortlessly prove with just their knowledge and passion why Chicago is the true home and king of the skyscraper.

[@chrisclouds4182]

[@pibbitybibbity]

I have always loved these type of windows and am glad to know the name and history behind them. I grew up in several western U.S. states in the ‘70s and many of the Craftsman bungalows have them, as do many of the ranch-style homes built in the ‘50s & ‘60s. They’re very nostalgic for me.

[@roccobierman4985]

Absolutely brilliant episode. Chicago is so abundantly blessed with great architecture, it's amazing.

[@rosezingleman5007]

I spent a lot of time documenting bungalows all over the US. Chicago windows are very common to them in the upper Midwest and they’re really lovely. My adult children and I will be driving somewhere and they’ll say, “look Mom, Chicago windows!” Yeah, I’ve made them into architecture buffs.

[@christopherstephenjenksbsg4944]

Excellent video Stewart! Your mention of Louis Sullivan's Auditorium Building brought to my mind his Carson, Pirie, Scott building constructed ten years later in 1899. He uses an infill frame rather than the free-standing facade of the Auditorium building, and he uses Chicago windows everywhere except at the lowest level with its display windows (which are amazing in themselves). I know a big problem with early curtain walls in NYC has been the deterioration of the hangers between the steel frame and the applied panels of stone, terra cotta, or glass. There have been several full or partial collapses of the curtain walls since the 1970s, and several people were killed or badly injured in those accidents. Has this been an issue in Chicago, or is this an example of the original clients and designers cutting too many corners and paying off building inspectors to look the other way? (The NYC Buildings Department has been a den of corruption for nearly 150 years.)

[@n11743]

Wonderful. I greatly appreciate these videos. And I'm happy to learn that I've brought the "Chicago window" into my renovation of my small house in Madison, Wisconsin. Thanks again.

[@The_Smith]

Great video, I've always liked the look of that style of window, didn't know it had a name or the reason for it's function. In my part of the world they weren't unusual in houses built in the 1950's, sort of a step between the sidebyside sash and picture windows I guess.

[@gratefulot360]

Fascinating! Thank you, Stewart.

[@Erdnussbuttertoast]

absolutely insane that he decided against insulated glass during the redevelopment of that skyscraper. I guess since he doesn't live in it, he doesn't care

[@lizsays3324]

He works in the building

[@MaritaCov]

And is old enough that the climate change from heating poorly insulated buildings won't affect him.

[@WeezieLou]

The client (owner of the building) makes the final decision about what kind of glass to use - not the architect. The architect can make recommendations, but unless they’re paying for it, it’s up to the owner.

I really think highly of your video as you explained the utility of Chicago windows in early skyscrapers, the origins of and manufacturing process for the polished plate glass used to make them and the method to incorporate them into the building façade…most would leave out all of these important and fascinating details!...watched it 3 times!!

[@simonbowden8408]

Fascinating video again. Thank you Stewart for showing us how rich the world is when one scratches underneath the surface. We think architectural styles are about freedom, while actually they are often more about constraints, on materials (plate glass and steel), and on basic human needs (warmth and light) and on economics. And all these constraints intersect with each other as Stewart describes vis the gas field and glass manufacturing costs. Incredible that the first skyscrapers had gas lights, though I remember when smoking was allowed on airplanes. I think one could critique architects like Hadid for using the almost limitless structural possibilities to build buildings where the shape looks like it comes from an architect's sketch on a napkin - where the building maybe reflects a jazzy concept that the architect sold a client with too much money & freedom. I'm building a house for myself and modifying a Richard Rogers apartment and appreciate the constraints of trees, site, and structure. Without that the world might have to put up with my nutty ideas.

[@paint4pain]

I like this mix of history in the video, I'd love a run of city/area inspired vids like this one. In Montreal we have the twisty outdoor staicases that are the result of rules and regulations mixed with booming ironworks industries.

[@theaeon]

A lot of modern German windows have a similar-ish design! except they tend to be two parts, with one side being larger, the other a little smaller. That way you can use the windowsill for plants or knick-knacks and just leave the small side free for airing out the room. Alternatively, pretty much every German window is able to tilt inwards, and that way you can get some airflow going as well, without opening the entire window. (One difference to the chicago window being, that both windows tend to be openable.)

[@stephenmoerlein8470]

Interesting discussion of the Chicago Window. Thanks for posting.

[@LMays-cu2hp]

[@aes53]

Great video Stewart, you always make my Thursday. The technology of plate glass is what is referred to as “float glass” and, as you pointed out, it revolutionized the possible applications of glass. The way float glass worked was that molten silica is poured out onto the surface of molten tin. The fact that it was floating kept it flat and made it possible to make large sheets. Modern plate glass probably uses something other than tin but that was how it started.

OMG, I love this video - and it seems personal for me. My first temp job when I moved to town was for an architectural and engineering firm, and Gunny was a big shot there. I later temped in the Marquette building for the MacArthur foundation - lots of history all around. I know next to nothing about architecture, but I find it fascinating. Perhaps it's time for me to finally take one of the tours...

The best way to get ventilation going with sash windows is to open both upper and lower part. This way hot, less dense air leaves the room via the upper part, while fresh, cooler air goes in via the lower part, without turbulence and mixing. This setup actually allows quadruple exchange of air compared with a regular open window of the same size. A pretty ingenuous design, if operated as intended.

[@achannelandnothingmuchelse]

Iceland has a very similar window that's very iconic. It's essentially the same as the Chicago window except the side bits open to the side, like a door, instead of up and down. Sometimes it's on one side and sometimes it's on both!

There are building's in various cities in which were not built for actual people and the various reason's one would utilize the building. They generally house thing's that would be considered eye sore's if they were outside in view of the general public. Such as various venting for sewer systems, relay station's for communication system's, internet sever system's. And they install various blackened out Chicago style window's. Often having a lightling system that is programmed to turn off and on making it look as if it occupied.

I work for one of the largest window and door companies in the US and my first position with this company was making multi unit windows. One of the most common styles of windows we made was Chicago windows though I didn't know the term for them until now. One thing to note is that these days the large center window can be opened. In the plant I'm in we make large awning units as large as 73"x73" though when I started with the company units wider than 35" were all fixed. I also find the term operable sash to describe the double hung units on the sides interesting, this brought up a question to me, if only one of the sashes is operable would it be a single hung unit? Also should I really be watching videos about windows after coming home from my job in a window factory?

Homes in the Midwest typically feature a Chicago window in the front of the house( living rooms). Allows light to enter but, takes in account the unpredictable weather( gloomy, overcast, lots of rain). Air circulation is the added bonus.

[@lynn858]

Thinking about the two way sashes that open top and bottom to encourage cool air in and hot air out. I'm guessing high ceilings in these type of buildings (as opposed to residential) would affect how effective that could be, and not worth the added cost?
