Container City
Founded in 1998, Container City were the early adopters of conversions in the UK and one of the first to dream big, creating multi-unit buildings across London, and beyond. The OG, Container City 1 from 2001, was stacked at Trinity Buoy Wharf in East London and inspired many to follow the innovative footsteps - myself included.
See this video from 15 years ago when Channel 5 featured Container City 1 for its Behind closed Doors series.
