The House
Coffee, without ornament.
The shop is named for a number. 21 grams is the mass of ground coffee in a double shot, the unit from which every other drink is derived. The site is painted in two fields: black and white. The rooms keep their colour. The menu is written the same way.

Purist, not precious.
We do not flavour coffee to make it interesting. The interest is already in the shot: origin, roast, yield. Milk is steamed to a specified texture. Water is dosed in ounces. If a drink cannot be written as a ratio, it does not belong on the board.
A chain of houses.
Clapham is the main house. Wimbledon, Battersea, and Fulham keep the same board. Each room will look like a house, not a template. The point is not expansion. It is repetition, the same 21 grams, wherever you stand.
