Movable chairs have been a feature of Parisian parks since the 18th century. Chairs are more comfortable than benches, and movable ones allow you to direct yourself toward the sun, cluster in groups, or just situate yourself so that you can prop your legs up and read a book.

Now, here's a brief story of how this came to be.

At the outset of this innovation, park chairs weren't free. If you wanted a bench upgrade, you had to pay. Private concessionaires would rent them out to visitors (like umbrellas at a beach), maintain them, and presumably ensure that things were kept generally tidy around the grounds.

Then, around 1923, the iconic green Sénat chair was designed by the Ateliers de la Ville de Paris. If you've ever been to Paris, you know this chair (see cover photo). It comes in only three models: chair, armchair, and recliner, all of which are green. RAL 6013 green, to be exact.

Eventually, the Sénat chair was imposed as the Parisian park chair. By 1955, it was the only possible option that could be rented out by concessionaires in places like the Jardin du Luxembourg. This set the stage for it to become one of the most recognizable symbols of the city.

But due to the popularity of these chairs and the fact that people would rather not have to pay to sit in a park, it was decided in 1974 that the chairs should be free, and they were bought from the concessionaires.

In 2002, Frédéric Sofia designed an offshoot of the chair called the "Luxembourg." The Luxembourg is made of aluminum, as opposed to steel, and is therefore lighter. It's also available for sale to the general public, whereas the Sénat chair is exclusively for city parks.

The result of this centuries-long tradition is an iconic symbol for the city and an established culture of employing movable chairs in public spaces. A humble movable chair may not seem like a big deal, but in the world of public spaces, it is.

Try to incorporate movable chairs into a park or public space today and, invariably, someone will tell you that it can't or shouldn't be done. They will say the chairs will be stolen, vandalized, and/or weaponized by hooligans. Perhaps not.

Today, there are some 4,500 movable chairs in the Jardin du Luxembourg alone. Paris shows us that it can be done.

I recently came across this tweet by Patrick Collison, the CEO of Stripe, where he argues that the YIMBY movement "employs an inadvertently dishonest sleight-of-hand" when it promises "Paris-scale density" only to ultimately deliver something quite different in cities.

In the post, he shares a fairly banal mid-rise development that looks nothing like Paris, and then says that if we're talking about Paris-style building, he'd be all for it, and likely voters would be too. His point seems to be that if only we made developments more beautiful, fewer people would oppose them.

I had to read the tweet a few times to make sure I was understanding it correctly because the "Paris-scale density" language was throwing me off. Paris is not a medium-density city. It's a high-density city and generally considered to be the highest-density city in Europe. Is this the Paris promise?

I don't actually think most people want Paris; they want a city that looks like Paris, and that's because they ignore most of its urban ingredients and only focus on the two most obvious things: (1) its outward architectural expressions and (2) its modest building heights.

Paris-scale density is single-stair buildings with minimal setbacks and stepbacks, dark light wells, tiny 130-square-foot studios in the penthouse, no parking minimums, and area population densities that can exceed 50,000 people per km2. Is this what most voters want, provided they look pretty?

For the purposes of this post, let's just run with the argument that urban environments people broadly feel are beautiful would elicit less NIMBY opposition. Just build Paris-like buildings. Unfortunately, I also don't think the answer is as simple as this.

As Sam Deutsch of Better Cities points out, this runs counter to NIMBY history. Let's not forget that the Paris everyone visits today was vehemently opposed during the time of its initial development and that the city's most iconic structure was called a hateful column of bolted sheet metal, among other things.

Beautiful buildings and great places are, of course, fundamental to cities. But even then, expect turbulence along the way.

Between 2010 and 2025, the Métropole du Grand Paris added nearly 160 kilometres of new or extended transit lines and opened 200 new transit stations across the region. These numbers include all modes of transport, including RER, metro, tram, cable cars, and BRT. On top of this, a further 199 new stations are scheduled to open between 2026 and 2032 (a shorter time period), meaning there's an argument to be made that Paris is getting better and faster at delivering transit.

Imagine that.

This, as we have talked about before, is a remarkable achievement and one that is reshaping the Métropole — particularly outside of Paris proper. Take a look. Here's a recent study and map from Apur that shows how these completed and upcoming lines have impacted, and are expected to impact, transit access in the region:

The coloured areas represent access to transit within a 15-minute walk (assuming you're able to walk at a reasonable 4 km/hr). The lightest blue areas are lines/catchment areas that existed in 2010. The medium blue represents lines/areas that came online between 2010 and 2025. And the darkest blue represents lines/areas that are scheduled to come online between 2026 and 2032.

If you're familiar with Paris, you'll be able to tell that the majority of the recent transit expansion has happened outside of the boundaries of Paris. This is important because prior to 2010, all of Paris was already well-served by transit (seriously, 100% of the population was/is within walking distance of at least one transit line).

However, this is not the case in the rest of the Métropole. In 2010, about 56% of the population (outside of Paris proper) had access to at least one line, with 23% having access to two. As of 2025, this number has increased to 66%. And by 2032, with the opening of the lines currently underway, it is expected that 80% of the population within the entire Métropole will be transit-connected.

It's hard to overstate the importance of these changes. The Paris region has long been criticized for the divide that exists between its historic centre and its surrounding suburbs and cities. Historically, this has been a socio-economic divide, and a built form divide. But this divide is now being erased. New infrastructure is stitching the region together, tightening its geography, and encouraging the development of new economic centres.

Forget the Paris you know. The growth and change are now happening along its edges. Welcome to the new Greater Paris Metropolis.

P.S. To commemorate the 10th anniversary of the Métropole du Grand Paris (created on January 1, 2016), Apur recently published a book called Atlas de la Métropole du Grand Paris. I haven't been able to find a site that will ship to Toronto, but if you're in Paris, you can order or pick one up at the following bookstores.
