MOST designed the interior fit-out of Happy Electron’s 500 sqm headquarters and research facility in North Acton, London, combining specialist battery-development space with a distinctive workplace. Flexible laboratories and a separate testing area support equipment-intensive research, while an open-plan office, private meeting rooms and shared amenities bring the team together. A double-height meeting and kitchen space forms the social heart of the facility. The design balances clean technical environments, adaptable working arrangements and a strong identity for an emerging energy-technology business. Photography: Happy Electron Ltd.
