The three-storey west London headquarters of the fashion brand Sister Jane and its partner restaurant Cha Cha x Sister Jane. Taking into account the shared aesthetic of the two brands, Sella Concept redesigned the building's interior and branding to give it a unique retro warmth. The design is also inspired by the form, shape and use of space in the 70s, and there is a movement and warmth in its past design history, which the studio combines with the modern.

The three-storey townhouse incorporates a restaurant, a showroom and an office where employees can plan and design future clothing collections. On the roof there is also an outdoor terrace where visitors can gather for drinks.

On the ground floor of Sister Jane Townhouse is the restaurant, called Cha Cha's, which serves up a roster of Latin-fusion brunch dishes. The space has peach-coloured walls and is dominated by a huge hexagonal, brass-edged bar counter. It's surrounded by a series of Deja Vu stools by Masquespacio that boast tiers of mauve, cream and beige fringing.

Upstairs in the showroom, surfaces take on a pinkish hue. Some clothes are displayed within a veiled pod that sits at the centre of the room, enclosed by sheer white curtains. Other garments hang from custom-made walnut rails or are presented on mannequins which perch on a curvaceous platform covered in teal-blue carpet.
