OPSO is an all-day restaurant situated on the corner of Paddington Street and Nottingham Place in the London neighbourhood of Marylebone. The brief was to create a design that would reflect the overall philosophy of the restaurant: Greek inspired, London made. For this concept to come across successfully the design, the menu and the branding had to come together coherently in one identity. We worked closely with the whole team to ensure that the design of the space is seen as a natural physical extension of the OPSO concept. By stripping back the façade and gutting the 2000 square feet of existing space, the true fabric of the building was revealed. The main ground floor space is long and narrow and divided into 2 zones by a 20cm difference in the floor level. The focal architectural element of the design is a central spine that connects the two zones by running the length of the space and incorporating the level change within its use. Beginning in the first zone and at the main entrance, the spine is a 1m 10cm high coffee bar that casually welcomes diners and take away clients.
