A view is probably the strongest justification for this type of picture window, and this one is a stunner. While I'm not sure if the windows astride the picture window are operable, their width puts the emphasis on the squarish central pane.
It's clear that this picture window brings in lots of daylight, aided by the clerestory that straddles the fixed and operable windows below. While more traditional than the previous example, note how the windows extend close to the floor, making the wall almost completely glazed.
The large picture window at the end of this living room bring in light as well as some green; the latter is in the form of the bamboo that sits just outside.
The Chicago window can be traced to the city's tall buildings that dotted the Loop around the turn of the 20th century. Later high rises also used the window to structure curtain walls. This project takes advantage of a large picture window through the placement of the dining room table and the window treatment.
Here is another high rise with a picture window that takes advantage of the lake view.
This subtle variation on the Chicago window locates the operable window below the central pane.
Chicago windows aren't just for living rooms and bedrooms. Here is an example of a study that strategically orients the chair with a view out the central pane between hung windows. In my opinion, it's always good to have a spot to daydream while working.
Leaves fill a picture window in a eating area adjacent to the kitchen, looking much like a painting.
Kitchens are great rooms for variations on Chicago windows, ones that are shorter but also impressive in terms of views. Here one can enjoy the trees and water beyond while washing the dishes.
Again we see the large fixed picture window above the sink.
Here is yet another example of a picture window above the sink. Plenty more glass is found to the left and right, but the operable windows are located by the sink to offer ventilation for the kitchen and whoever is doing all the work.
This shows what an amenity picture windows above sinks can be.
These last few examples show variations on the Chicago window. Here we see a bay with a corner window and an operable awning below the central fixed pane. The bay is deep enough to work as a bench, a nice perch for looking at the view.
Here is another bay with windows on the sides and operables below the large central pane. This low band of awning windows is just about at a person's head height while seated on the built-in, providing a cooling breeze.
This example is two thirds of a Chicago window, as only one casement window flanks the large fixed pane. This seems appropriate, given the scale of the room and length of the wall. The horizontal aspect ratio of the picture window also makes sense, given the water view.
