The studio apartment lies up on the fourth and top floor of a plain 18th-century building with a rendered facade punctuated with stone courses. The edifice stands in the very heart of Île Saint-Louis island. It offers around 25m² of floor area – or around 15m² of liveable floor area according to France’s Carrez law. The communal areas are decorated with old fireplace plates. A timber staircase with a balustrade of wooden balusters bears witness to the historical character of the edifice. The apartment faces south. It is bathed in an abundance of natural light. You can see the River Seine from it. The interior designer who renovated the dwelling chose an optimised single-space design. A fitted kitchenette with oak units has been discreetly integrated into the studio apartment and a shower room with a lavatory lies behind a glazed partition wall. Old hexagonal terracotta tiles adorn the floor. They go well with the stone fireplace – a second-hand item from a chateau that adds a touch of nobility beneath the exposed beams of the roof frame. Each detail has been carefully considered, from the bespoke cupboards to the 19th-century sculpted doors and the flower-patterned cast-iron radiator. A wardrobe is fitted discreetly beside the shower room. The recent renovation has not only given the place real comfort, but also a D rating for energy efficiency.
