The province of British Columbia made the following announcement this week:

The Province has updated the BCBC to remove the [building] code requirement for a second egress, or exit, stairwell per floor in buildings up to six storeys. This change will make it possible to build housing projects on smaller lots and in different configurations, while allowing more flexibility for multi-bedroom apartments, more density within areas of transit-oriented developments and the potential to improve energy efficiency in buildings. Previously, the BCBC called for at least two egress stairwells in buildings three storeys and higher.

This is meaningful progress. And BC is the leading the way in Canada. But from a global perspective, we are not leading the way. This is us catching up.

As part of this building code change, the province commissioned a report on single egress stair building designs. In this report, they looked at various jurisdictions from around the world:

Their non-exhaustive findings:

There are at least 30 jurisdictions with SES building design requirements that permit midrise buildings with a building height of at least 5 or 6 storeys. In addition, the Center for Building in North America (www.centerforbuilding.org) reports that 8 US states have passed legislation into law, or are reviewing possible options for doing so, to allow larger SES buildings when their Building Code is next revised. In most cases these revisions are intended to allow SES buildings of up to 6 storeys.

For example, Seattle already allows up to 6 storeys. Belgium, New Zealand, and Australia allow up to 9 storeys (driven by a maximum height in meters). And Finland allows up to 18 storeys, according to the report.

Though keep in mind that building codes are complicated and often have frustrating gray areas. There may be other requirements that need to be met in order to achieve these heights.

It's great to see BC making these moves. Now watch for other provinces to follow suit.

This is an important chart from a recent study commissioned by Greater Wellington, New Zealand. The study looks at the cost benefits of urban intensification and the above chart shows the relationship been density and infrastructure costs. For this study, they specifically looked at the costs that local governments face in providing road, public bus transport, and "three-waters infrastructure." I hadn't heard this latter term before, but it refers to drinking water, wastewater, and stormwater.

What they obviously found was that there are real economies to higher densities. More density lowers the per dwelling cost of delivering infrastructure. In the case of three-waters infrastructure, it doesn't even really matter if you're proximate to reservoirs or treatment plants. The bulk of the cost lies in the local connection pipes. So what matters most is how many dwellings you can service off of the main lines -- even if these lines need to be upsized.

The goal of this study is to enable more support for smart growth within the Wellington region:

Regional councillor Thomas Nash says the report should give councils confidence to press on with plans that support compact mixed-use development in and around city centres and connected by high quality public transport. 

“Regional growth needs to be smart growth. This report clearly shows that the best bang for our buck is to focus on upgrading existing water, public transport and local roading infrastructure so that we can build better quality, compact residential form, with improved amenities within our cities and towns,” Cr Nash says.

Of course, this doesn't just apply to Wellington. Every city should read the study.

Regular readers of this blog will know that I am huge fan of the YouTube channel Never Too Small. I have seen most of their episodes and I like to tell people about it even when it is only remotely related to the conversation at hand.

I love the urbanity of it all. There is just something so satisfying about turning constrained spaces into homes that are both beautiful and functional. It also makes you question how much space you really need.

But if constraints aren't your thing, and you'd like to see a wider variety of homes, another great channel to check out is The Local Project. The homes -- which are all in Australia and New Zealand -- are equally as beautiful, but tend to be more, uh, extensive. See above video.

What are some other channels worth checking out? It seems to me like Canada needs something similar to The Local Project. Maybe it already exists.
