Watchhouse was founded in 2014 by Roland Horne in a 19th century former watch house on Bermondsey Street, London. The roastery sits beneath a repurposed railway arch on Maltby Street, where the team roasts on a refurbished 1959 Probat UG22 under the direction of Head Roaster Nikol Novotná. Rather than selling wholesale, the company made a deliberate decision to channel all its energy into sourcing and roasting for its own outlets and online shop. That focus now spans 17 locations across London, with an expansion into New York in 2024. Coffees are sourced seasonally from producers worldwide and organised into three ranges: the 1829 Espresso blend designed for milk drinks, the Rituals range for comfort, and the Horizons range for more experimental offerings. All packaging uses compostable plant based materials, and their decaf is processed using ethyl acetate in Nariño, Colombia.
