# Construction is about to begin on the new Tour Montparnasse

At the end of this month, the [last tenants will vacate](https://www.euronews.com/travel/2026/02/23/iconic-paris-observation-deck-set-to-close-for-renovations-next-month) the Tour Montparnasse in Paris to make way for its renovation. Nouvelle AOM, a collective of architects formed to respond to the project's international design competition, first won the commission back in 2017. And initially, the plan was to complete the renovation in time for the Paris Olympics in 2024.

But that time came and went, as it does, and now construction is starting this year. Nouvelle AOM, which includes Franklin Azzi Architecture, ChartierDalix Architectes, and Hardel Le Bihan Architectes, is in charge of the tower. And Renzo Piano Building Workshop is in charge of redesigning the commercial podium at the tower's base.

We've spoken about the Tour Montparnasse many times over the years on the blog ([here](https://brandondonnelly.com/the-eiffel-tower-and-the-awful-tower), [here](https://brandondonnelly.com/the-tour-montparnasse-just-turned-50-and-people-still-hate-it), and [here](https://brandondonnelly.com/la-tour-montparnasse-at-ground-level)). Parisians customarily hate it, and after visiting it in 2023, I can confirm that it's desperately in need of a renovation, and that the ground plane experience is abysmal at best. It is of that era where grandiose "slab-based planning" was going to elevate us beyond the pathologies of fine-grained urbanism.

Here's a Google image from atop the site's enormous podium:

What's interesting about the design from Renzo Piano is that it will reuse a lot of the structure that's already in place. The plan is to carefully open up the site, stitch it back together with the surrounding urban context, and then build up from there. Importantly, at the centre of the project will be a large, planted piazza that is intended to become a new civic space for the community.

The project renovations are expected to last until "at least 2030." So, we have several years until we'll know if it's an urban and financial success. But my prediction is that this project will positively transform how Parisians think about the Tour Montparnasse, and maybe how they think about tall buildings.

The tower itself will, of course, need to be beautiful. It's a highly visible object. There's only a trifecta of buildings and structures inside Paris proper that exceed 150 meters in height: the Eiffel Tower, Tour Montparnasse, and the Tour Triangle (Herzog & de Meuron), which is currently under construction and expected to finish this year. In this case, [architecture is not irrelevant](https://brandondonnelly.com/sometimes-architecture-is-irrelevant).

But it is the ground plane experience that will ultimately revitalize the area and demonstrate that tall buildings can be good urban neighbours, even in a sea of Haussmannian mid-rise buildings. I've said before that the reconfiguration of the podium is arguably the project's most crucial design move.

Get it right and you'll see what happens.
