British Transport police faced the problem of providing a new Custody Suite within a reasonable distance of the centre of London, but were unable to find a plot of land that was either suitable or affordable.

The answer was to build a complete custody suite 'off-site' and assemble it in an existing warehouse adjacent to their Brewery Road HQ, resulting in significant savings of both time and money.

The 27 steel framed modules, comprising of holding cells, interview rooms, and support offices were craned into place, after the roof of the warehouse had been taken off. Once the modules were sited the roof was replaced, therefore minimising disruption.

Full compliance with the rigorous standards demanded for custodial accommodation ensured that the users of the suite are unable to recognise that the facility was not built by traditional means.
