Australian studio Biasol has combined unevenly finished concrete walls with pale green fixtures and neon signage inside this day-to-night dining spot in central London.

Farmer J is situated on King William Street in the office-dense area of Monument. It is the second branch of the restaurant to open in the capital, joining an existing site in Leadenhall.

Selling healthy breakfasts, lunches and dinners, the restaurant caters to city workers as well as casual diners. The "all-day-trade environment" encouraged owner Jonathan Recanti to establish a new branch that reflects the brand's versatility and variety of service.

Recanti charged Melbourne-based studio Biasol with designing the restaurant, having already been a fan of its hospitality projects, including a marble-rich eatery inside London's historic Royal Exchange building and a Wes Anderson-inspired cafe in Chengdu.

"By merging the concept of grab-and-go with a full-service restaurant, together with Farmer J we redefined the perception of fast dining, elevating the experience and brand," said Jean-Pierre Biasol, principal at the studio.

The space has been arranged around a grooved timber counter where food is prepared. On the opposite side of the room is a curved bar clad in sage green tiles where customers can order coffee or enjoy cocktails later in the evening.

In between sits a mix of stool seats, leather-backed booths and communal tables intended to "blur the zoning of service types".

All of the walls have been hand-rendered with concrete, with splashes of colour coming from an abundance of vine plants that wind down from shelving units, and a variety of potted succulents.

Lighting is provided by spherical white pendant lamps that hang from the ceiling.

"Our colour inspiration came through completing the freshness of the food offering and differentiating the Farmer J brand from any of its competitors in the marketplace," continued Biasol.

"We wanted to evolve their brand, add a level of maturity, and help grow their business."

A wooden arch has also been erected at the rear of the dining space, framing a neon text sign that states Farmer J's brand motto.

Much like Biasol, London architecture studio Red Deer paired washed plaster walls with mint green floors and furnishings for the interiors of Soho delicatessen Lina Stores.
