The significant expansion of HMP High Down is a major asset to the custodial estate, and was the first of its kind to be delivered under the Prison Capacity Programme.

The brief

The brief was to design two new 180-cell houseblocks, a new education facility, workshops and a two-storey secure corridor system to radically improve the quality and safety of the environment.

Our response

The construction of this refined houseblock design captured months of design development within the professional team. This result provided the Ministry of Justice with an exemplar model for accommodating category B prisoners across its entire estate.

Key facts

  • We achieved a BREEAM Excellent rating.
  • These were the first precast accommodation buildings of their kind in the custodial estate.
  • The expansion helped reduce staffing levels due to improved sight lines.
  • Our design also reduced health and safety risks.
  • This 36-month project was delivered on time and to budget.
