I am endlessly fascinated by some of the small homes that get built in Tokyo. This one, also pictured above, is called the Borderless House.

Designed by Selma Masic — in collaboration with Sei Haganuma (Haryu Wood Studio) — the house sits on a 3-meter-wide lot, has a total area of 63 square meters across three floors (~678 square feet), and allegedly houses a family of four. Bridgestone also appears to be its immediate neighbor.

To put these dimensions into perspective, 3 meters is roughly the width of a “typical” new apartment living room here in Toronto. Usually, if you have a floor plate that can accommodate an outboard bedroom up at the glass, you design for a structural grid somewhere between 6–6.5 meters.

This gives you around 10 feet for the living room and around 10 feet for the bedroom. (As a a Canadian, it's important to always bounce back and forth between metric and imperial.) In this case, the entire lot is only 3 meters wide, though a corner lot always enhances a floor plan.

All of this is fascinating because, compared to North America, it represents a completely different way of conceptualizing space. Of course, the point of posts like this one is not to suggest that this is what all homes should be like. The point is that there are benefits to allowing those who would like such a home to be able to build it.

Bianca and I went for a walk around the Junction over the weekend, as we like to do, and I was pleasantly surprised to find a number of "multiplexes" under construction. That is, small infill rental projects with four or five homes, sometimes including a laneway house at the back. (Sorry, no sixplexes were spotted just yet.) It immediately made me think, "Wow, it's happening! Toronto is intensifying its neighborhoods."

For those of you who haven't been following closely, many of Toronto's neighborhoods have been bleeding population over the past few decades. It's only where we've allowed larger-scale new developments that we've really seen populations increase. That's what has precipitated our current push to expand housing options in our low-rise neighborhoods. And already, you can find evidence that it's starting to work.

That said, it's worth mentioning a few things. Some of the planning notice signs that I stumbled upon dated back to 2022, and some were current. This raises at least two lines of questions. One, why is a small project that went to the Committee of Adjustment in 2022 still under construction? Was it because of planning delays, or something else? And two, why are today's projects still having to go to the CofA? Are we still not there yet in terms of the planning policies?

I don't know the precise answers to these questions, but I do know that planning staff actively monitor which variances are requested and ultimately approved. If the same variance continues to show up, then it's a clear indication that it should just become policy, and not be something that needs to be sought. This should give some comfort that we should only get better at facilitating this scale of housing.

Yesterday morning I reshared this tweet of a recently completed mid-rise building at 58, rue de la Santé in Paris. And the response was overwhelmingly positive. There was a long list of people saying: please build this in my city, I want to live here, I want to invest in projects like this, and more.

Based on the echo chamber that I live in on the internet, it would seem that most people like this project, and are wondering why Paris can build it, but we generally can't. So let's take a closer look in the hopes of learning something. Here's an image from Google Street View:

The developer for the project is RIVP (Régime Immobilière de la Ville de Paris). They are a major social housing developer in the city and are semi-public company, primarily owned by the City of Paris. They build, manage, and renovate social housing, and have somewhere around 66,000 housing units under management in the île-de-France region.

The project contains 14 social housing apartments and one commercial unit at grade. It's 8 storeys tall (R+7 is the nomenclature commonly used in France which means rez-de-chaussée plus 7 additional floors). And on its main elevation there are only two small stepbacks at level 7 and 8. Otherwise the building goes straight up.

The site area is 191 m2 or ~2,055 ft2. This is the equivalent of a single-family housing lot measuring around 20 feet x 100 feet, which would be fairly common in Toronto. Except in this case, it's not just for one family; it's for 14 of them and a commercial user on the ground floor.

The total area, according to the above site signage, is 909.40 m2 or ~9,789 ft2. That crudely works out to about 60.6 m2 per unit (I'm including both the residential and commercial units in this very rough calculation). This is exactly similar to what I would expect to see here in Toronto in terms of an average suite size.

The floor space index for the site (i.e. its density) is 4.76x. This is not particularly high and is probably on the low side compared to what you'd typically find in Toronto for new mid-rise developments. The key difference here is that they're achieving it on a relatively small site.

The total height of the building is 23.46m. Divided by 8 floors, that works out to a floor-to-floor height of 2.93m. This is a bit tighter than what I would expect, but it seems to be because the ground floor is relatively compact, whereas Toronto developers are encouraged to be greater than 4.5 meters tall.

The project architect — MAAJ Architects — specifically mentions on their website that they used concrete in order to keep the height of the building down. They also show the building as being taller and having 16 apartments, so I'm guessing height was constraint.

The big question that remains is: how much did it cost to build? And I unfortunately don't have a good answer for this. Precise hard costs are generally hard to find and total development costs are almost never published.

That said, the architect does show on their website a hard cost figure of 2,630,000 € HT for 1,242 m2 (again, it looks like an earlier design of the project was bigger). These figures work out to €2,117 per m2 or €196.70 per ft2 or C$289 per ft2.

Don't quote me on these figures. I don't have inside information or first-hand experience in this market. But if it's even remotely accurate, then I'd say it's at least 30-40% cheaper than what a comparable build — with hand-laid bricks — would cost in Toronto.
