The bar counter has a standard marble top, but the sides are an impressive feature – the marble panels have been ground to a 5mm thickness, allowing light to shine through. The panels were mounted on Perspex for strength, and two LED strips with diffuser shine through the panels to create a creative effect that can be seen through the glass walls by passers-by and customers.

In the kitchen area, LED panels are built into the ceiling to provide good working light for the chefs and kitchen staff.

To the front of the building, colour changing RGB LED downlights give the bar a voguish appearance. The lights are controlled by an app to alter the colour and speed of colour change. The same lights are used, in spike format, in flower beds, shining up at trees that line one side of the site. Bench seating in this area is highlighted by LED strips in warm white.

Landlords Princesshay, a joint venture partnership between The Crown Estate and TIAA Henderson Real Estate, required Class A in all aspects of the build, including lighting.
