Tucked under the arches of London Bridge, in the foodie haven that is Borough Market, is the latest venture by Hotel Chocolat founders Angus Thirlwell and Peter Harris: the Rabot Estate store.

This 800 sq ft shop offers premium products in weather-worn surroundings, selling chocolate products from the eponymous cocoa plantation in St Lucia.

The shop is a fine example of rough luxe and Terry Moore Designs has been careful to cultivate this impression. Recycled wood, painted brickwork and corrugated iron form the fundamentals with upscale treats shown in reclaimed crates, barrels and mid-shop islands fashioned from recycled materials.

There’s a cafe too, providing a place to perch while sampling cocoa tea (a Caribbean speciality) with the menu chalked on a blackboard. This back-to-basics graphic treatment is replicated across the interior with signs stencilled on slate shards or directly onto the walls in a packing case-like font. High levels of daylight spill into the cafe from a completely open front and in the cavernous internal recesses naked bulbs hang from exposed rafters.

The store is at ease with its surroundings, meeting the market’s criteria for ethical and premium produce. The missing external wall makes it less a shop and more like the stalls opposite. Concrete floors also blur the distinction between store and surrounding market.

The reach-me-down chic of this ersatz Caribbean shack has a St Lucian flavour that is sympathetic to the traditional traders found in this location, yet somehow different. And it has just celebrated its first birthday.
