Lower Ground · 2022

Strip-out & cycle store

Principal Contractor
Duration
4 weeks
Value
£120,000

The first programme. Caecus took the lower-ground floor back to a CAT A office shell — partitions and ceilings down, walls made-good and painted, services capped and re-routed — and dropped in a secure cycle store with channel drainage to the perimeter. Service-sensitive: the package sat alongside the building's main intake and the lift pit.

Two years on, CBRE called us back for the ground floor.

Level 3 · 2025

CAT B → CAT A reinstatement

Client
Cushman & Wakefield UK Ltd
Role
Principal Contractor
Duration
12 weeks
Value
£420,000

The largest programme of the three, and a different client. Caecus stripped the existing CAT B fit-out back to slab — partitions, ceilings, services, raised floor — and reinstated the floorplate to a market-ready CAT A: new metal-frame raised floor, suspended ceiling grid, perimeter trunking, fan-coil reinstatement, fresh finishes, made-good lighting, full BMS commissioning. Twelve weeks from possession to handover, with the M&E re-balance running into the final fortnight.
