In 1920, the renowned Swiss-French architect Le Corbusier started to develop the concept behind what was to become his Unités d’Habitation buildings. These vast concrete apartment buildings went on to be enormously influential and are often cited as the initial inspiration for the Brutalist architectural style and philosophy.

The first and most famous of Le Corbuiser’s Unités d’Habitation buildings was La Cité Radieuse in Marseille, which was built from 1947 to 1952. Constructed in rough-cast concrete with its instantly recognisable primary-coloured panels, it was designated a UNESCO World Heritage Site in 2016 and a historic monument by the French Ministry of Culture.

Set over 12 storeys, La Cité Radieuse was built to house 337 apartments, two indoor streets of commercial units on the third and fourth floors (currently occupied by a hotel, restaurant and a number of high-end stores), a nursery school and an art gallery, all topped by a expansive communal terrace featuring sculptural ventilation stacks, a running track, a shallow paddling pool for children, an open-air stage, a children’s art school in the atelier and unobstructed views of the Mediterranean and Marseille.

The building’s design incorporated 23 different apartment types, the most common being a two bedroom split-level duplex. It was a (very) faithfully preserved version of one of these duplex apartments that we stayed in during a recent visit to Marseille.

The apartment was arranged over two levels, opening from the seventh floor corridor onto a mezzanine level containing the original Cuisine Atelier Le Corbusier type 1 kitchen and a dining area overlooking the living area below. A Jean Prouvé-designed open tread steel staircase led down to the lower floor of the apartment which stretched all the way from one side of the building to the other with a balcony on each side (the building was designed with a interlocking scissor layout – the apartment across the corridor had a staircase leading to an equivalent upper floor spanning the entire width of the building).

The lower floor living space contained a living area, a bathroom with separate toilet and shower cubicle built into a cupboard-like pod and two long, narrow bedrooms at the opposite end, each with their own sink and dressing area and divided by a sliding door. All of the rooms were furnished with original free-standing and built-in furniture, including “storage walls” with various cupboards with sliding doors designed by Charlotte Perriand in collaboration with Atelier Le Corbusier.

So, what was the experience of living in a perfectly preserved (i.e. almost completely unmodernised) Le Corbusier apartment like? It was definitely an experience. Certain aspects of the original design still worked well – the double height ceiling and window over the living area was dramatic and allowed plenty of light to flood into both the upper and lower floors of the apartment, enhanced by the dual aspect on the lower floor. The extensive built-in storage was functional and attractive.

Other things worked less well: the way that the lower floor stretched all the way from one side of the building to the other combined with the relatively narrow width of the apartment made it feel a little corridor-like, especially the bedrooms which were particularly long and thin.

The original kitchen, while beautifully preserved, was lacking from a practical perspective by modern standards (the oven was particularly difficult to use without scorching yourself) and the less said about the claustrophobic shower in the windowless cupboard (painted black, no less), the better. Lastly, those gorgeous-looking Charlotte Perriand sofas in the living room made for the least comfortable seating I have ever sat on.

The communal areas of the building and roof terrace (even though the shallow pool had been drained for the winter when we visited in March) were, however, spectacular.

I understand that you can join a tour of the building which includes access to at least one of the apartments. If were to redo our visit to Marseille, I would probably join that tour rather than rent an apartment for the full authentic experience of staying in a Le Corbusier building.
