“When a rooftop has a green cover, comprised of plants in raised beds, tables, or trellises, it shades the apartments on the upper floor, preventing overheating, especially in buildings that lack proper insulation, as is often the case in informal settlements. Rooftop gardens also reduce the heat that concrete structures absorb throughout the day and then re-emit at night, keeping cities cooler overall.
In Jeddah, Saudi Arabia, one of the world’s hottest cities, a study showed that indoor air temperatures in buildings with rooftop gardens were as much as 12 degrees Fahrenheit cooler than those without gardens, even during the warmest hours of the day. That saves on energy, too, which can have knock-on environmental effects. Research also shows that even relatively small rooftop gardens can reduce surrounding air temperatures by more than half a degree Fahrenheit”
Tiny Houses in Urban Context
I’ve seen a lot of really great tiny home designs, and I’ve seen a lot of love from other people for those designs as well. They combine a small space, perfect for one or two people, that usually only apartment buildings design for, with the benefits of having a detached home, with a yard, and windows on all sides for more natural light.
What I don’t see is a whole lot of context, least of all in an urban neighborhood environment. These houses are often pictured in an open grassy, or forested space, which is nice for some people I’m sure, but there are lots of people who would prefer to live in a city, in pedestrian and transit friendly areas, rather than in the middle of nowhere, where you’d have to use a car to get everywhere.
There already exists an urban context for tiny homes, but due to restrictive zoning, it’s not commonplace in most cities in the U.S.
They’re called Bungalow Courts, or sometimes Cottage Courts, and basically it’s where you take two adjacent lots, and rather than having one large single-family-house per lot, you have around 3 or so tiny houses per lot, all facing a shared space in the center.
All this takes up the same space as two city lots, which are usually zoned to only allow one house per lot. But not everyone wants, or can afford a large house, so Bungalow Courts would be a perfect fit in a lot of neighborhoods that currently lack a lot of housing diversity for a range of wants and needs.
Anyway, I just thought I’d share, because I think this a really neat concept that should be allowed more places. I’d think I’d like to live in a Bungalow Court; I like the idea of having a house to myself, but I don’t need much space, and I don’t want a huge yard to maintain.
In order to make this legal to build out, zoning would need to be changed to allow 3-4 units of housing to be built on lots currently restricted to only 1 unit of housing. A big contributing factor to rising housing costs has been the over-favoring of single-family houses on large lots since the end of WWII, so not enough units of housing are being built in many cities to keep up with demand.
Legalizing more “missing middle housing” like Bungalow Courts in single-family-house-neighborhoods would help cities incrementally keep up with demand, in a way that fits nicely into existing neighborhoods.
Secret city design tricks manipulate your behaviour
When Selena Savic walks down a city street, she sees it differently to most people. Whereas other designers might admire the architecture, Savic sees a host of hidden tricks intended to manipulate our behaviour and choices without us realising – from benches that are deliberately uncomfortable to sculptures that keep certain citizens away.
Modern cities are rife with these “unpleasant designs”, says Savic, a PhD student at the Ecole Polytechnique Federerale de Lausanne in Switzerland, who co-authored a book on the subject this year. Once you know these secret tricks are there, it will transform how you see your surroundings. “We call this a silent agent,” says Savic. “These designs are hidden, or not apparent to people they don’t target.” Are you aware of how your city is manipulating you?
In 1999, the UK opened a Design Against Crime research centre, and authorities in Australia and the US have since followed suit. Many of the interventions these groups pioneered are familiar today: such as boundary marks painted around cashpoints to instil an implied privacy zone and prevent “shoulder surfing”.
San Francisco, the birthplace of street skateboarding, was also the first city to design solutions such as “pig’s ears” – metal flanges added to the corner edges of pavements and low walls to deter skateboarders. These periodic bumps along the edge create a barrier that would send a skateboarder tumbling if they tried to jump and slide along.
Indeed, one of the main criticisms of such design is that it aims to exclude already marginalised populations such as youths or the homeless. Unpleasant design, Savic says, “is there to make things pleasant, but for a very particular audience. So in the general case, it’s pleasant for families, but not pleasant for junkies.”
Preventing rough sleeping is a recurring theme. Any space that someone might lie down in, or even sit too long, is likely to see spikes, railings, stones or bollards added. In the Canadian city of Calgary, authorities covered the ground beneath the Louise Bridge with thousands of bowling ball-sized rocks. This unusual landscaping feature wasn’t for the aesthetic benefit of pedestrians walking along the nearby path, but part of a plan to displace the homeless population that took shelter under the bridge.
So next time you’re walking down the street, take a closer look at that bench or bus shelter. It may be trying to change the way you behave.
This does explain to me why I would come across crazy designs such as these in the cities I come across.
