Sussex Office Fit Out & Refurbishment

Our Fit Out Services

Sussex Fit Out & Refurbishment Specialists

Your local specialists for CAT A, CAT A+ and CAT B office fit outs — based in Worthing, delivering across the county.

Faction Interiors is a Sussex office fit out company delivering commercial interiors for businesses, landlords and property professionals across the county. From our base in Worthing, West Sussex, our construction and design teams plan, manage and build office fit out projects in Brighton, Chichester, Crawley, Horsham, Eastbourne and everywhere in between — combining local knowledge with the standards of a national contractor.

Whether you're a business relocating to new premises, a landlord preparing space to let, or an agent or architect who needs a dependable delivery partner, we take projects from first idea to final handover.

Office Fit Out Services in Sussex

Every project is different, so our service flexes to suit yours. As principal contractor, design-and-build partner or specialist subcontractor, we provide:

  • Design & Build — a single point of contact from concept drawings through to completed workspace, with design, costing and construction handled in-house.

  • CAT A & CAT A+ Fit Out — preparing commercial space to a lettable standard for landlords, agents and developers, including white-boxing of shell-only units.

  • CAT B Fit Out — transforming open floorplates into finished, branded workspaces: partitions, glazed screens, ceilings, joinery, kitchens and breakout areas, decoration and flooring.

  • Office Refurbishment — re-imagining tired space for end users and landlords without the cost of relocation.

  • Pre-Construction Support — measured surveys, building appraisals, estimating, cost analysis and landlord/legal support before a single wall goes up.

CAT B Fit Out in Sussex

A CAT B fit out is where an office becomes your office. Taking a blank CAT A floorplate, we install everything your team needs to move in and work: partitioning and glazed meeting rooms, suspended ceilings and acoustic treatment, bespoke joinery and carpentry, teapoints and kitchens, decoration, flooring and furniture.

Because partitioning, dry-lining, ceilings and internal glazing are our leading in-house trades, we deliver CAT B projects in Sussex with fewer subcontractors, tighter programmes and better value than contractors who buy everything in. We work occupied or out-of-hours where needed, keeping disruption to your business to a minimum.

Recent CAT B work includes full office fit outs in Brighton — see our work for project photography.
