Studio Libeskind has a recently completed project in Brooklyn that looks like it was designed by Studio Libeskind. It has angled facades and, judging by the comments on Dezeen, its design is polarizing. But it is an affordable housing project for seniors, and it does have a large atrium in the middle of it.
Atria are a bit of a unique feature in multi-family housing (at least in this part of the world). For better or for worse, the gold standard has become the double-loaded corridor. And that's because it's "efficient." It helps you maximize the amount of rentable or saleable area to gross construction area.
Here in Toronto, a typical efficiency -- calculated as the net saleable/rentable area divided by the gross construction area -- would be somewhere between 75-80%. Though many factors can affect this percentage, such as the amount of amenity space in the building.
There is certainly the option of just building a less efficient building, but then it means you'll likely need to increase the price of the homes to compensate for this loss in efficiency.
This is the trade-off that is often made with smaller suites. More and smaller suites usually translate into more corridor space (i.e. a lower overall efficiency). But it may make sense to do this if you think your smaller suites will generate more revenue on a per square foot basis.
Off the top of my head, I can only think of two residential building in Toronto with an atrium. And that's 71 Front Street East in the St. Lawrence and "The Atrium" at 650 Queens Quay West. The latter is pretty neat inside. The last time I checked, it even had fake palms.
In the case of both The Atrium and Libeskind's Brooklyn project, the atria result in single-loaded corridors. (I'm not sure how 71 Front was designed.) Here's what Libeskind's project looks like:
The obvious advantage of this condition is that you get natural light into the corridors, whereas with a typical double-loaded corridor you don't. But again, the disadvantage of this design is that you only have apartments on one side, instead of both sides.
In this case, the thermal envelope of the building is the outside face of each corridor (atrium side). This means the corridors are interior or conditioned spaces.
Another option would be to create open-air corridors, like in this example from Montreal. This creates corridors exposed to the elements, but now you've reduced your overall energy consumption (less space to heat/cool) and you've created the possibility of double-aspect units.
Personally, I'm a fan of atria and courtyards in residential buildings. But for the reasons we just talked about, they're not that common. My sense is that they're far more common in commercial buildings. John Portman, for instance, made a name for himself designing and developing hotels around them.
What are your thoughts, though? Would you pay a premium to live in a residential building with a nice atrium? I bet some of you would if it meant an improved suite design, such as more windows and more natural light.

I came across this apartment on ArchDaily this morning and I immediately thought to myself, "this looks like the Lagoa neighborhood of Rio de Janeiro." (Rio is one of my favorite cities and we nearly spent a few weeks of winter 2021 in this particular area.) So I opened it up and it turns out I was right. It's a recent apartment renovation, in this building, by Rio de Janeiro-based architects MZNO.
I then got onto the floor plan:
Circular building floor plates invariably create fan-shaped suite layouts like this one here. From my experience, these can create some really beautiful spaces up near the face of the building, but they tend to work better when you have a bit more space to play around with. You're also going to end up with diagonal walls and probably a radial structural system. In this case, the suite is just under 1,000 sf.
I wondered if this might have been two suites that were joined together, with the previous demising being the radial shear wall behind the couch (see above). There seems to be two entrances to the suite on this plan. But then I looked at active listings in the building and this seems to be a typical layout. So I think they just stripped things down to the existing structure in order to open up the plan.
The other item that stood out to me on the plan was the long corridor off the primary bedroom. But again, looking at other plans in the building, I can see that it was initially designed as a walk-in closet. This makes more sense, but it's also a compromise brought about by this being a relatively deep plan.
The bedrooms are "tetrised" together to make efficient use of a limited amount of linear glazing. An alternative trade-off (in this second plan) would have been to give it more frontage, and then bury the office (escritório). But I suppose there's a good argument to be made that it's better to have more light in your office than in your bedroom.
MZNO was probably thinking along these same lines when they designed the linear kitchen in the way that they did in the first plan. By aligning it perpendicular to the suite's exterior glass, you're able to gain access to a view and some light even when you're toward the back of the suite.
Finally, the other thing about circular buildings is that they allow you to do cool circulation spaces like the above. In this case, all of the common area corridors are single-loaded, and wrapped around a huge lightwell in the middle of the building. This maybe isn't so good if you suffer from vertigo, but it's obvious that these corridors are serving as an extension of people's living areas.
And since this is Brazil, they're naturally filled with greenery.
