The following diagrams were taken from LSE’s Urban Age website. I’ve sorted them from lowest to highest peak residential population density. In each case I’ve also included the year of the dataset.

It’s amazing how much these simple extrusion diagrams can tell you about the city. It also shows you that high population densities don’t necessarily need to equate to tall buildings. Barcelona, in particular, stands out for me.

For the past week or so I’ve been seeing the proposed Kettle Boffo Project in Vancouver make the rounds online. Here’s a rendering of the project, which is located at Commercial Drive and Venables Street:

The Urbanist recently published a guest post, called Let Us Build Backyard Cottages, that sounds a lot like a post I wrote a few years ago, called Why It’s Next to Impossible to Get a Laneway House Built in Toronto.
It’s the same story: buy house; see opportunity to build low-cost well-designed backyard cottage (or laneway house); discover the countless obstacles in front of you; give up until the land use policies become more favorable.
Here’s the Seattle version of the story (via The Urbanist):
I bought my home in 2014 with the intent of building a backyard cottage on the property. The property is a mere 4,080 square feet, with a large flat backyard that is mostly wasted space. The plan was to buy a small, prefabricated, and super-insulated (to Passive House standards) house. We would install it and move into it while we brought the main house up to Passive House standards as well, adding insulation and ventilation. We would then move into the main house while my parents (who are currently living on the East Coast, and want to move closer to us) move into the backyard cottage.
Unfortunately, Seattle’s backyard cottage requirements proved too onerous for us to move forward with building one. The requirement of an additional parking space was a bit irritating (especially considering that my family lives car-free near the future Roosevelt light rail station), despite the fact that we do technically have two parking spaces. But more frustrating than that, it was the owner-occupancy requirement that made us scrap our backyard cottage plans.
What I find interesting about all of this is that the same narrative is happening in multiple cities, from Seattle to Toronto. That, again, suggests to me that change is likely inevitable. Especially since Seattle seems further ahead in this regard compared to Toronto. Change is happening.
Of course, there are differences between accessory dwelling units (what The Urbanist wrote about) and independent laneway housing (what I wrote about). But I would classify them as being in the same family of urban change.
Most North American cities are clinging to a specific kind of single family housing typology. I can appreciate why. But I believe that there will be a tipping point.
I’m not sure that this year will be the year. Which is why I didn’t include laneway housing in my list of 10 city building predictions for 2016. But I think it will happen in the shorter term.

The reason it has been making the rounds is that a community group called NO TOWER (written in all caps) has come out in fierce opposition of the 5 to 12-storey building. They have over 3,500 signatures.
As an outsider looking in, this is surprising. The scale of the project seems appropriate. The height roughly matches the existing building shown above to the right. It may even be lower. And the project will provide somewhere around 30 social housing units, as well as additional space for the Kettle Friendship Society non-profit, who are currently on the site. (Note: An application to the city hasn’t yet been made.)
What this has me thinking about is the push and pull between bottom-up and top-down planning.
When architect Bjarke Ingels talks about his Dryline project in New York, he likes to refer to it as the love child of Robert Moses (top-down planning) and Jane Jacobs (bottom-up planning). In the case of this project, it’s because it’s a large infrastructure project that they are trying to root into the local neighborhoods. Makes sense.
But this same thinking could also apply to overall city building. Local communities rightly have their own wants. But at the same time, cities need to be thinking about the overall. The challenge is finding that right balance.
I would be curious to hear your thoughts on the Kettle Boffo Project in the comment section below – especially if you’re from Vancouver.
