A central structure of light oak conceals the private quarters without interrupting the wall-to-wall windows and has carved out an L-shaped living and dining area. On the side of the dining room, a kitchen unit has been incorporated into the oak structure, featuring a terrazzo worktop and pink cabinets which gracefully complement the adjacent green dining table, a bespoke design whose soft curves taunt the rectilinear cabinetry.

The green and pink shades in the dining area are picked up in the lounge, the former by the colour of a wall section and the latter by the luxurious custom-designed sofa in three reddish pinks. The candy-coloured palette is playfully juxtaposed by the cool concrete floor and ceiling, while the soft texture of the Berber rug is contrasted by the glistening marble of the modernist coffee tables. It is all part of Ester’s whimsical design of contrasts—curved and straight, rough and smooth, common and opulent, colourful and restrained—which bestow a sense of wonder without saturating the senses.

This sense of wonder is further titillated by a slew of clever surprises. An austere wall of gray-painted wooden slats conceals a brightly painted blue wardrobe, the oak-panelled volume contains a cubist bathtub of light gray marble terrazzo, next to which is a Carrara marble washbasin block set below a wallpaper based on Hokusai’s The Great Wave off Kanagawa. The biggest surprise though awaits guests outside, where an exterior staircase leads to a private roof garden designed in collaboration with landscape architect Anja Knoth, offering sweeping views over the whole of Berlin. Conceived as a series of volumes and platforms and styled with oriental references, the decked roof garden reflects both the morphology and the colourful élan of the apartment below, as well as Ester’s unique sense of style.​.
