HMP Thameside is a category B custodial environment, housing 1,200 men, both convicted and on remand. We constructed HMP Thameside to reduce pressure on existing local facilities and provide an efficient, safe and green prison in London.

Split-contract approach

The first contract was to build the prison, the second was to create an extension. This split-contract approach enabled a safe and secure operation throughout the build period.

The prison offers accommodation and facilities for education, rehabilitation, medical treatment, training, sports, worship, visits, administration, horticulture and security. Inmates can also improve their skills with the prison’s vocational training workshops.

Water and energy saving measures

Built using environmentally friendly materials wherever possible, the prison is designed to make water and energy use more efficient. Water-saving measures include time/flow limiting controls and dual-flush systems on toilets. A building management system monitors energy use and an intelligent lighting system ensures they automatically turn on and off, as required. Further energy-saving measures include:

  • high heat recovery air handling systems
  • low-energy ventilation fans
  • air source heat pumps

Our team also trained the prison operations management team to use the new facilities, delivering a prison that:

  • performs more efficiently
  • improves maintenance and replacement management
  • minimises energy use
  • could reduce staffing levels without compromising safety or security
  • minimises whole-life facility and per-prisoner costs

World first

The main living unit was the first prison building in the world to achieve an ‘outstanding’ BRE environmental assessment method (BREEAM) rating, while all nine of the other buildings have an ‘excellent’ rating.
