Evolution façade, Covent garden, London


St Martin’s Courtyard, originally developed in 2011, has recently been refurbished. This is a mixed-use restaurant and retail destination and the architects, Brimelow McSweeney, wanted a particularly eye-catching new coating for facades and panelling enclosing the courtyard space and its entrances. The objective was a finish that would appear to change in colour and tone as the sun moves across the sky, finally being illuminated from within the panels as dusk falls. 

The Solution

Working with the architects, we developed a bespoke textured red/gold powder coating within our Evolution range, a collection that reflects the beauty of natural metals and metal patination. Brimelow McSweeney and the developer visited our plant to see powder coating in action and discuss the shade they were looking to achieve. We made a range of Evolution sample panels and  the final choice was a red/gold shade with a highly textured surface, rather like large golden rain drop. It seems to glow, with or without sunlight. We called it ‘Molten Rain’.

Around 500 m2 of flat and perforated aluminium façade were coated. Large petal shapes formed by perforations in the aluminium are illuminated by light-boxes at night to create a warm and welcoming atmosphere.

This unique shade forms an appealing backdrop for visitors enjoying eating, drinking and shopping within the courtyard space.
