A geometric wall mural and a berry-toned bedroom appear inside this central London penthouse, which has been created by fashion designer Roksanda Ilincic.The apartment is set inside one of three 19th-century gasholders that WilkinsonEyre and Jonathan Tuckey Design converted into luxury residences early last year.

The focal point of the Roksanda-designed apartment is a huge geometric mural in the dining area, hand-painted by Swiss artist Caroline Denervaud. Featuring blush-pink, sandy beige and navy blue forms, the wall provides a warm backdrop to the room's pale marble table and breakfast island.Simple white cabinetry and brass hardware have been incorporated in the adjacent kitchen.

Another piece by Denervaud can be seen in the living room, attached to the wall with simple gold bulldog clips.Other than a couple of bright-yellow fibreglass chairs, the colour palette here is kept neutral with a curved white sofa, floor-to-ceiling timber bookshelf and perforated cane seats by Swiss architect Pierre Jeanneret.Pale pink Kvadrat curtains hung in front of the full-height windows lend the space a rose-tinted hue.
