What CI3 LIMITED does

CI3 LIMITED (legal entity Ci3 Eridge Limited) is a commercial interior design consultancy founded in 2007 and headquartered in Sittingbourne, Kent, UK. The firm delivers end-to-end workplace projects covering four integrated service lines: Design (concept through production information), Fit Out (partitioning, ceilings, electrical, mechanical, IT and telephony), Moves (relocation of staff, product, technology, and storage), and Furniture Procurement. Projects are scoped from initial brief through on-site installation, with the firm positioned as a single point of responsibility across design, construction coordination, furniture supply, and relocation.

The core product offering is a bespoke consultancy service rather than a software platform; underlying technology consists of standard digital design tools and a paperless, remote-friendly operating model. The firm is a UK dealer for the MillerKnoll collective (Herman Miller, Knoll, HAY, Muuto, NaughtOne, Colebrook Bosson Saunders) and additionally sources bespoke joinery via craftspeople in the UK, Turkey, and Morocco. Customer base is concentrated in enterprise commercial sectors, with documented project delivery across the UK, the Netherlands (Amsterdam), and the USA (Dallas).

Revenue mechanics combine professional-services fees (design, fit-out, moves) with transaction-based furniture procurement margins. Pricing is quote-based and not publicly disclosed. Go-to-market is direct B2B enterprise sales plus referral through design firms and architectural partners. The Murray family maintains ownership and operational control, supported by a deliberately small team of around five employees. The firm operates commercially within the contract interiors and office furniture sub-sector of the UK professional services market, competing against larger multi-office design-build firms on design quality and single-point accountability rather than scale.
