Two City of London buildings on Fleet Street, a Category A and shell-and-core refurbishment led by Mace Interiors for CBRE — and every life-safety and security system in both, delivered by one team, from design through independent witnessing to BCO sign-off on 13 March 2026.
Peterborough Court — the former Daily Telegraph headquarters on Fleet Street — and neighbouring Daniel House were refurbished as a dual-building commercial campus. Gemini AMPM was appointed by Mace Interiors, with CBRE as end client and operator, to deliver the integrated fire, life-safety and security package: fire detection and alarm, public address / voice alarm, disabled refuge, aspirating smoke detection, IG55 gas suppression, access control, video door entry, CCTV and intruder.
The project ran from design through installation, commissioning and independent witnessing to formal certification — closing 89 witnessed commissioning items across the two buildings and completing a 14-day monitored soak test before practical completion was achieved with same-day BCO sign-off.

of monitored soak testing before practical completion
Advanced MxPro 5 panels networked across 28 nodes, carrying over 3,200 Hochiki addressable devices — with aspirating smoke detection in critical zones and interfaces to fire curtains and the Nimbus Connect BMS. Designed, installed and commissioned to BS 5839-1.
Baldwin Boxall Vigil 3 public address / voice alarm with zoned, staged-evacuation capability to EN 54-16, and Omnicare Plus disabled refuge with two-way speech at refuge points to BS 5839-9:2021.
IG55 inert-gas suppression protecting the MER and SER plant rooms — clean-agent protection for the buildings’ critical infrastructure with no water-damage risk, delivered to ISO 14520 / BS EN 15004.
Genetec Security Center Synergis with HID Global readers — speed gates, QR-code visitor access, Apple Wallet credentials and CBRE app integration, plus face-recognition video door entry, to BS EN 60839-11.
Over 130 Hikvision IP cameras covering entrances, public areas, plant rooms and service zones — a GDPR-compliant deployment to the BS EN 62676 series.
81 Ajax Systems wireless devices at Grade 2 under BS EN 50131, with cloud-managed reporting delivered under our NSI NCP 104 accreditation.
A project like this is won or lost in coordination. Gemini worked to the fire strategy authored by OFR Consultants, within the MEP and cause-and-effect design of Chapman BDSP, alongside architect JRA and network-cabling partner Onnec — with every system independently witnessed by HDR before certification.
Cause-and-effect across 28 fire-alarm nodes, staged evacuation, curtain and BMS interfaces, suppression interlocks and integrated security meant the systems had to be proven together — not just individually. The 14-day monitored soak test and same-day BCO sign-off at practical completion is the evidence they were.
