I had an interesting meeting today talking about the structural approach behind this OMA-designed project in Brooklyn (pictured above).

I have always found structural engineering fascinating. Structures, along with physics, were some of my favorite classes from high school all the way to grad school. So even though I don't think my personality is ideally suited to engineering, if I were ever to become an engineer, I'm fairly certain that I would need to be a structural one.

For this project the big structural challenge was the large cantilevers that you see above in the tower on the left. As I understand it, there a number of ways to deal with this. One way would be to just design large transfer slabs and/or beams. But given the size of this tower, these would end up being very deep, and so you'd be really compromising the spaces where these structural transfers occur.

How they actually dealt with it is through sloping columns (which you can see in the above photo if you look closely). What these columns do is gradually transfer the loads across multiple floors in the building, until they reach structure that runs all the way down the tower.

At the same time, the spaces underneath the sloping columns are essentially "hung" from above. Meaning the columns are in tension, instead of being in compression, which is typically how columns work. The result is that you get some sloping columns in the suites. But I think that's kind of cool. If you're nerdy enough to care, it tells you how the structure of the building is working.

Obvious disclaimer: I am not a structural engineer. You probably want to consult one if you're looking to do a cantilevered tower with sloping columns.

Earlier this week, Slate Asset Management and Forum Asset Management submitted a new development proposal for 100 Lombard Street in downtown Toronto.

At the time of writing this post, the applications (zoning by-law amendment and site plan control) hadn't yet hit the city's website. So here's some information about the project, including its big moves:

• This is the first mixed-use residential project in Toronto designed by the Office for Metropolitan Architecture (OMA). The proposal includes residential, office, and retail spaces.

• Architecture by OMA and WZMH Architects. Heritage by ERA Architects. Landscape and public realm by Claude Cormier + Associés. Planning by Urban Strategies. Structure by Stephenson Engineering.

• The principal architectural idea is to create a vertical urban village through a series of "urban rooms" interspersed throughout the tower. These spaces would serve as amenities for the building and house a variety of different functions. See above rendering.

• The proposal introduces three important public realm moves: (1) a new public plaza that pays homage to the site's former neighbor to the east -- Second City; (2) a new mid-block pedestrian connection running north-south from Richmond Street East to Lombard Street; and (3) an outdoor public art gallery featuring oversized art tableaus.

• The site currently houses one designated heritage building (86 Lombard Street), and the design contemplates relocating and fully retaining this building on the eastern edge of the site. Once you see the drawings, you'll fully understand why this was the most logical move.

The entire project team is very excited to get this proposal out and into the world. And we hope that you will see it as being representative of our ongoing and lasting commitment to elevating architecture, sustainability, culture, and city building in Toronto.

The new OMA-designed Taipei Performing Arts Center opened up last Sunday and so you'll now find lots of articles, photos, and drone videos circulating around online. The two partners-in-charge, Rem Koolhaas and David Gianotten, were also on this Monocle on Design episode talking about the genesis of the project and how they worked to optimize the various theater spaces.

My favorite part of the whole story is how they actually won the design competition. The site is located next to Taipei's renowned Shilin Night Market. And I can attest to this fame because I spent a summer living in Taipei while I was in university. This night market was the thing I was immediately told I needed to visit as soon as I stepped off the plane. And they weren't wrong. I spent many a nights with those stinky tofu dishes that smell like feet but actually taste pretty good.

But for whatever reason, the competition brief stipulated that the night market was to be torn down in order to make way for this new performing arts center. And since it was in the brief, almost everyone took it as a non-negotiable given. The only firm that didn't -- out of 140 bidders -- was OMA. They questioned why the city couldn't have both: a new performing arts center and their wildly successful night market.

So that's how OMA -- at least partially -- won the competition. And I'm certain that Taipei is better for it.
