The neoclassical house with white facade and shiny roof is prized as Le Corbusier’s first independent piece of work – and a notable break from the regional art nouveau. Architecturally unrecognisable as Le Corbusier to anyone familiar with his later work, it sat derelict in the leafy hilltop neighbourhood above La Chaux until 2004, when the modern architecture treasure was renovated and refurnished (with some original furnishings).
