HMP Five Wells

Constructing Excellence

HMP Five Wells represents a step change in the evolution of offsite manufacture and sets new standards for excellence in innovation, collaborative working and sustainability. Completed on time and to budget, the prison provides around 1,700 places and features a design that is 80% standardised. This design is the first of its kind and will be used to deliver a further five new prisons in the coming years.

With repeatable, standardised components, the use of offsite manufacturing and sustainable features making it 70% more energy efficient than traditional facilities, HMP Five Wells is a brilliant example of the use of Modern Methods of Construction and provides a blueprint for infrastructure delivery for the construction industry. Its innovations will result in better outcomes both for the prison estate (faster, greener, more efficient delivery) and for prisoners. Secure barless windows and smaller wings support rehabilitation by creating more normalised surroundings.


Three Winning Facts:
  1. Standardised design
    The prison design is 80% standardised and repeatable, allowing it to be used across the next 20,000 prison places for the MoJ.
  2. Offsite manufacture
    Our innovative use of offsite manufacture saved 30% in on-site resource and resulted in assembly that was 22% faster than traditional construction.
  3. Social value
    The project generated a £135m social return on investment. Key achievements include the creation of 227 new jobs, 27 of which were filled by ex-offenders. Over the course of the project we recruited 19 ex-offenders and 8 men on ROTL, helping us to exceed the prison leaver employment target by 36%.
