Parasitic architecture sounds like a bad thing because of the connotations, but you could make an argument that it is, in fact, the exact opposite. It is a way to better leverage existing structures and reclaim under-utilized urban spaces. Perhaps additive architecture would be a more appropriate name.

Here's one example. WARchitect recently completed this "skyscape apartment" on top of an existing 5 storey apartment building in Bangkok. It's about 1,600 square feet. And the entire space is organized according to the structural grid of the apartment building below.

Many/most structural systems have excess capacity because of a built in factor of safety. So for a small addition like this, I'm guessing that they probably just loaded up the existing column grid. It also looks like there were already stairs leading up to the roof of the building.

Years ago I looked at doing an addition on top of an existing apartment building here in Toronto and it ended up being a lot more complex than I may be making it out to be in this post. Mind you, we were looking at adding on a few floors, which triggered all sorts of issues.

But now that Toronto is allowing accessory dwelling units along its laneways, is it time that we also look at the rooftops of our existing buildings?

A colleague in the office recently introduced me to a Swiss invention called the Wickelfisch (or baby fish). Below is a video showing you how they work. They're so neat. So Swiss. And I obviously just ordered one. They're available via this US company for $12-20, depending on the size.

The video is of people swimming in the Rhein. Because swimming downstream in rivers -- and ending up in a different location -- is so popular in Switzerland, the Whickelfisch was invented as a way to keep your clothes and belongings dry. It also acts as a flotation device.

I'm not planning on floating down the Don River anytime soon, but a Wickelfisch looks like the perfect bag to bring to the beach. Especially if you don't want to leave your stuff unattended to while you go for a swim.

Of course, the other neat thing about this video is that it shows you how awesome it is to have clean and swimmable water running through the middle of a city. Most people I know are afraid to swim in Lake Ontario out of fear they might grow a 6th toe.

That's too bad.

I was in a meeting the other day and we started talking about a wayfinding sign that indicated it was a 10 minute walk to the nearest subway station. We wondered who had made this sign and ultimately decided that the number should be 10. Either they had no idea where the subway was or they were being ultra conservative in their estimate. The subway was -- at most -- 5 minutes away.

We then joked that if a developer had made the sign it would say 2 minutes, which I thought was telling. Some people like to describe real estate development as an exercise in risk mitigation. And that is certainly something that needs to be managed. But it's also an exercise in resiliency, as you get every possible obstacle thrown in front of you. It's as if the goal is not to build anything.

So while it's important to manage the possible risks, I believe you have to be a bit of a glass-half-full kind of person in order to continue the march forward. Otherwise you'd probably give up. My first boss out of grad school used to describe it as reaching into the mouth of a tiger when everyone else figured it was over. I saw her do that time and time again and it made her great at what she did.
