Resident design studio Emma Donnersberg's Dart Apartment in New York City is a private residence for her Instagram followers, and its size marks it as no ordinary project. Donnersberg said it had to be big enough to hold a dinner party for 12 people, almost a mansion by New York City standards. Initially, her work with fans went so well that she was soon tasked with designing the 465 square meter space, which was dizzying for a Parisian who grew up in Gothic and Beaux Arts style buildings.

Initially the apartment was the fan's only asset, and it had no inherent charm. Its space is like a box, and the designer had to bring it a little different sensory enjoyment. To this end, Donnersberg introduced smooth feminine lines into the house, such as the white wool-covered wavy living room sofa, which she commissioned from a favorite French decorator with a small Office in New York.

The young family now has four children under the age of 10, so Donnersberg split the space into two parts to give the children and their parents their own space. She also wrapped rich cityscapes -- panoramas that change with daylight, weather and season -- in a mottled, cloud-like hue at the client's request.
