After noticing all the untapped potential of rooftop space in London, Patrick and Johnno set up a farm on one in Paddington, with the idea of growing and supplying fresh produce to people working locally, and Square Mile Farms was born. The urban farming company now puts hydroponic vertical farms (that’s growing without soil) into offices, residential buildings and restaurants, to provide locals with fresh local produce, to connect people with the food that they eat through harvesting sessions, and to encourage conversations about sustainability, nutrition and mental wellbeing.
