1Rebel is a new chic boutique brand of gyms in London. 1Rebel promises that every class feels like a night out. To achieve this, each gym is designed as a mix of contemporary industrial chic with luxury and theatrical glamour. Specified in all five locations by 1Rebel’s architects Studio C102, Knauf AMF Heradesign acoustic ceilings and wall absorbers help the architect fulfil this vision. Studio C102 Principal Kyriakos Katsaros: “I like Heradesign for two reasons. Firstly, as a practice, we prefer to use building materials in their raw state and Heradesign with its naturally textured surface creates a tactile finish and fits with our ethos and the gyms’ industrial aesthetic. Secondly, I wanted to make the environmental footprint as low as possible for the client. Heradesign helps us accomplish this because it’s produced from sustainable wood-wool.”
